China children’s programming market has huge room for growth in the future.

Children’s programming education is to cultivate students’ computational thinking and innovative problem-solving ability through programming game enlightenment, visual graphic programming and other courses. For example, in the process of making a small animation, students split tasks, drag modules and control the progress themselves, so as to understand the concepts of "parallelism", "event handling" and "goal realization". It is mainly aimed at teenagers aged 3-18.

In 2014-2019, there were frequent policies related to children’s programming education in China, and the policy support continued to increase. At present, the teaching scenes of children’s programming education in China are mainly divided into three categories. At present, children’s programming education enterprises take the B-end as the main style, supplemented by the C-end. By the end of February, 2020, there were 7,110 children’s programming companies in China, with Guangdong Children’s Programming Company leading the country, and the top 10 children’s programming education institutions were headquartered in Shenzhen, Beijing and Hangzhou. In 2018, the corresponding age population of children’s programming industry in China is about 236 million. In 2019, it was about 237 million people. China’s children’s programming market has huge room for growth in the future.

1. The development of children’s programming education in China has attracted much attention.

In 2014-2019, China’s children’s programming policies were released one after another. The country has realized the importance of education, and issued many related policies to encourage and support the continuous development of programming education and information education, and promote the popularization and deepening process of programming education at the national basic education level. The policy covers key provinces and cities such as Zhejiang, Shandong, Jiangsu, Tianjin and Chongqing.

2. Distribution of teaching scenes of children’s programming education in China.

The teaching scenes of children’s programming course are divided into three categories: non-public educational institutions, public educational institutions and families. By investigating the enterprises in the industry and comparing the landing degree in three scenarios, it is concluded that the current children’s programming education enterprises mainly adopt B-end, supplemented by C-end.

3. The headquarters of the top 10 children’s programming education institutions in China are concentrated in Shenzhen, Beijing and Hangzhou.

The children’s programming education industry in China has risen rapidly in recent years. With the blessing of multiple factors such as policy support and market maturity, children’s programming institutions have ushered in their own enthusiasm in the cold winter of capital. According to the data of Internet Weekly, the top 10 children’s programming education institutions in China are ranked as follows:

4. The number of children’s programming companies in Guangdong Province leads the whole country.

China’s children’s programming is still small in scale and relatively scattered in institutions, mainly distributed in first-tier cities such as Beishangguangshen and Shenzhen, and offline institutions are also mainly concentrated in first-and second-tier cities.

By the end of February, 2020, there were 438 children’s programming companies in China. In 2019, there were 7110 children’s programming companies in China. By the end of February 2020, domestic children’s programming companies were mainly located in Guangdong, Jiangsu, Shandong and Zhejiang, with 11,770, 3,529, 2,265 and 2,044 children’s programming companies respectively.

5. The overall corresponding age population of children’s programming industry in China is increasing year by year, and it is about 237 million in 2019.

The minimum age of children’s programming students in China is about 3 years old. At this stage, children’s cognitive and understanding abilities have reached a certain level and can begin to participate in such training. The oldest participants are 18-19 years old, that is, senior three students, and the population covered by the training generally coincides with the student group corresponding to K12 education. Therefore, Forward-looking Industry Research Institute adds up the number of students in kindergartens, primary schools, junior high schools and senior high schools in the national statistical bulletin on the development of education published by the Ministry of Education every year, and estimates the population aged 3-18 in China. From 2014 to 2018, the population aged 3-18 in China showed a slow growth trend. In 2018, the corresponding age population of children’s programming industry in China was about 236 million. In 2019, it was about 237 million people.

For the above data and analysis, please refer to Forward-looking Industry Research Institute, which provides solutions for industry, industry planning, industry declaration, and industry.

On February 17th, a video about a BYD new energy vehicle exploding and burning on a trailer in Yantai, Shandong Province was circulated on the Internet. According to the video, the towed car on the trailer started to emit smoke, then sparks began to flash at the bottom of the car, accompanied by crackling explosions, and finally it began to burn violently, and the whole car was quickly burned beyond recognition.

BYD Tang DM-i exploded and caught fire during consignment.

According to eyewitnesses, the incident occurred at about 1:10 pm on the 17th, near the East Yard of yantai mountain hospital, Guanhai Road, lai shan. At the time of the incident, the trailer was waiting for the green light at the intersection, but the bottom of BYD’s new energy vehicle towed by the car suddenly splashed with sparks, and there was a crackling explosion. Then smoke billowed, which ignited a fire, instantly wrapping the car body, and the car owners in the same industry drove away. At the critical moment, a nearby sprinkler arrived in time to put out the fire, and the fire was completely extinguished by the firefighters who followed, but at this time, this new energy vehicle had been burned to only one body.

At the scene of the accident, Yantai fire rescuers who came out to the police rescue told the verification media that fortunately there was no one in the car at that time and the cause of the fire was under investigation. BYD’s official customer service only said in the next day’s inquiry that the relevant information has not been received, and the specific reasons are still unknown, and it is necessary to wait for the investigation results to determine.

At present, it is not clear whether the car was consigned after the accident or failed to be consigned by itself, so it is impossible to analyze and define the main causes of its spontaneous combustion and fire. However, according to the live video, it can be found that sparks are constantly flashing at the bottom of the vehicle and crackling explosions are heard at the initial stage of the fire. From this, it can be roughly determined that the battery is indispensable for the violent combustion, and even the fire site may be the battery.

Judging from the body of the live video, it should be BYD Tang’s 2021 DM-i model that caught fire. The car was officially launched during the Shanghai Auto Show in April 2021. There are three models in total, and the price range is 189,800-216,800 yuan.

Tang DM-i is a heavyweight model introduced by BYD to replace the fuel version. According to the official statement, "it took nine years to finally produce this subversive model of Pratt & Whitney Volkswagen". The car is equipped with BYD plug-in hybrid system, which is composed of a turbo-charged 1.5Ti high-efficiency engine dedicated to Xiaoyun-plug-in hybrid of Miller cycle and an EHS electric hybrid system, and adopts Ferrous lithium phosphate "blade" battery dedicated to BYD hybrid.

Blade battery is an innovative product that BYD is proud of in the field of power battery. Tang DM-i is equipped with a power Ferrous lithium phosphate "blade" battery, which is different from the lamination process of BYD EV models, and adopts a winding process. Each group of blade batteries has a biscuit-shaped pole core, and a plurality of battery cells are integrated in series inside each pole core, while the whole battery pack is composed of a plurality of pole cores connected in series, and finally packaged into a "blade" battery. One of the outstanding advantages of this battery is that its heat dissipation capacity is good, and the battery uses Ferrous lithium phosphate as the positive electrode, so its performance is relatively stable, so its safety factor is relatively high in theory.

It is precisely because of this that Wang Chuanfu, Chairman and President of BYD’s Board of Directors, once said at the super conference of "Blade battery is unsheathed and safe in the world" on March 29, 2020, "Blade battery embodies BYD’s determination to completely end the safety pain point of new energy vehicles, and it will redefine the safety standard of new energy vehicles." "New energy vehicles equipped with blade batteries will completely erase the word spontaneous combustion from the dictionary of new energy vehicles."

BYD’s "blade" battery became famous in the first world war because of the puncture experiment, and it was spread in the industry. Later, it was fully promoted and applied in all models of BYD’s new energy, and made great contributions to BYD. Supposedly, such an innovative product should completely reassure consumers, but the reality is somewhat embarrassing for Boss Wang.

In fact, not only BYD Tang DM-i, but also Han DM-i, BYD e6, BYD e2, Qin Pro, Yuan EV, Song Pro DM-i, Seals and Dolphins. Just search the network news, and you will find that BYD’s new energy series vehicles have had fire or spontaneous combustion accidents, and some vehicles are still relatively frequent, and they have emerged from time to time on the network.

Original sin or quality problems in key parts

Take the protagonist Tang DM-i as an example. In recent years, spontaneous combustion accidents are not uncommon. For example, on January 26, 2022, some netizens broke the news that a BYD Tang DM-i in Shanghai caught fire on the way to the trailer. This is really a coincidence. The situation is so similar to this accident that Xiaobian thought it was the same incident at first, and then carefully identified the license plate number and confirmed that it was two accidents. This accident eventually led to the complete burning of the car.

Also in Shanghai, on March 19th, one month later, it was revealed that the BYD Tang DM-i newly mentioned by a car advocate in Shanghai spontaneously ignited in the parking space of the community. According to the information provided by the owner and the chat record, the car caught fire at around 5 am that day, which caused the car next to it to be burned to varying degrees. According to the owner, the car was not charged at that time, but just parked there.

This is only a corner of Shanghai, and it is only a short period of incomplete online exposure news. Search those online news that have not been deleted, and you will find that BYD Tang DM-i spontaneous combustion accidents are all over the place, and there are many more.

Objectively speaking, with the widespread use of new energy vehicles, fire accidents are indeed rising. According to the statistics of the Fire and Rescue Bureau of the Emergency Management Department, in 2021, there were 3,000 fire accidents in new energy vehicles nationwide. It seems inevitable that a hot-selling new energy vehicle will have some spontaneous combustion accidents, but the mistake is that BYD Wang’s boss should not talk too much.

What’s more, such an accident is a very disturbing disaster for any individual consumer. If there are casualties in the accident, it will be a family tragedy. Therefore, it is necessary to explore the causes of spontaneous combustion of BYD Tang DM-i, even Qin Pro, Yuan EV, Song Pro DM-i and so on.

On April 29th, 2022, a recall notice issued by the State Administration of Markets indicated that 9663 Tang DM models produced from September 2nd, 2021 to March 14th, 2022 would be recalled from now on. The reason for the recall is that the installation surface of the battery pack trays of these vehicles is uneven due to manufacturing reasons, and there is a risk of water ingress. "This may cause the electrical circuit of the power battery system to fail. In extreme cases, there is a risk of thermal runaway of the power battery, which poses a safety hazard."

On July 29th, 2022, another recall notice issued by the State Administration of Markets revealed that BYD had expanded the recall scope of Tang DM and decided to recall 52,928 Tang DM electric vehicles produced from April 5th, 2021 to April 18th, 2022 from now on. The reason for the recall is that "some vehicle power battery pack trays are at risk of water ingress, which may cause arcing in the high-voltage system and pose a safety hazard."

In fact, people who don’t understand these technical terms, whether it’s thermal runaway or high-voltage system arcing, may not be too concerned. But in other words, if the common people can understand it, it is: the battery is overheated to the limit, which will cause the battery to burn or explode; As for the high-voltage system, it is simpler to pull the arc. Have you ever seen the transformer switch on? "Zizi" sparks with lightning all the way, and the high-temperature arc generated by high voltage and high current can ignite the surrounding combustible materials in an instant.

Therefore, judging from the spontaneous combustion accidents of DM-i in Tang Dynasty, although BYD conducted cold treatment in most cases afterwards, and did not give specific reasons and follow-up news, it is not difficult to find from the official announcement that the quality control of DM-i in BYD Tang did have serious problems that might lead to spontaneous combustion, so that it had to start a recall.

Returning to this consignment spontaneous combustion accident, although the specific reasons are still under investigation, consumers can also reasonably doubt their quality control. In fact, we fully understand consumers’ concern about safety, but we don’t pay so much attention to the cause or process of the accident. Because no matter whether you are short-circuited, flooded, uneven or out of control, as long as your results lead to fire, spontaneous combustion or explosion, there is virtually no difference to consumers-from car burning to "human purgatory (if you can’t run away)".

As a leading new energy vehicle company, we should pay more attention to the reasonable concerns of consumers, especially the safety concerns, and we should not be negligent. After all, vehicle safety involves many aspects, not only batteries, but also supporting systems, body structure, etc. It is an organic whole, and no one can neglect it. If the quality control is neglected, it can also lead to the abandonment of all previous efforts. Therefore, BYD needs to make more efforts in product line quality control and ex-factory quality inspection.

　 　 　 　Cctv news Recently, with the success of Qingzhi Technology, an enterprise in Suzhou High-speed Railway New Town, in realizing the large-scale industrialization of intelligent driving products, and Innovusion (Tudatong) successfully completed the off-line of the 50,000th image-level ultra-long-range laser radar, the mass production capacity of enterprises in Suzhou High-speed Railway New Town in the field of intelligent driving has made a new leap forward, and "Intelligent Driving Avenue" is entering mass production.

　　According to the relevant person in charge of Tudatong, in July this year, the company has taken the lead in reaching the 10000th off-line of high-performance lidar. Facing the increasingly diversified application scenarios and the growing industry demand, the enterprise did not stop there. After three months of painstaking research, all resources were fully mobilized, and with the close cooperation of the team, rigorous debugging and testing, and deep running-in between the upstream and downstream of the industry, the production capacity finally climbed smoothly, achieving a breakthrough of 50,000 off-line image-level ultra-long-range laser radars, and boosting the large-scale application of high-performance laser radars in enterprises to a new level.

　　It is understood that TuDatong series products cover a complete combination of software and hardware, providing diversified solutions for different industries and application scenarios, and are widely used in different fields such as high-level assisted driving, automatic driving, intelligent networked cars, smart high-speed, rail transit and industrial automation. 50,000 image-level ultra-long-range laser radars are another big step for TuDatong to promote smarter, safer and better travel.

　　As the pioneer and main battlefield of the development of smart car networking industry in Xiangcheng District, Suzhou High-speed Railway New City actively seizes opportunities, plans ahead, tries first, and makes precise efforts in terms of industrial layout, platform building and policy support.

Many consumers think that the cost of buying a car plus the cost of maintaining a car every year is really a lot of money, but now taxi software is so popular that it is convenient and cheap to take a car, and it is not practical to buy a car. However, in bad weather such as cold or hot, carrying a heavy shopping bag or dragging a huge suitcase, or when the driver is in an emergency, he will feel the pain of waiting. Although cars are consumables, and even the rate of preservation is not high, there is no denying that owning a car of your own can really bring great convenience to life, such as going to go on road trip.

Today, we will take a look at the new car BYD Qin PLUS DM-i, including the design, rough interior, high and low performance, etc. Presumably, small owners have dived into major forums and dug countless evaluation videos, so there is no need to go into details in small series. Now, our focus is on the transaction price, discount, sales volume and value preservation of Qin PLUS DM-i, so as to help small owners who are basically targeting and waiting for the opportunity to start more comprehensively.

BYD Qin PLUS DM-i achieved a maximum discount of 95,900% on the transaction price in the past month, with the highest cash drop of RMB 4,800, and the national sales of new cars starting from RMB 125,900. The point price is for reference only, and the actual transaction price is subject to the local dealer.

The figure below shows the sales data of BYD Qin Plus DM-I. The national sales volume in the last month was 13,443 vehicles. I wonder if BYD is still satisfied with this achievement. Most people will follow the sales volume when buying a car, which is the main basis for most people to judge whether a car is good or not without in-depth understanding of a car. Although it is not accurate, it is not groundless, but if you have higher requirements for car selection, you need to make more efforts to fully understand it.

When we buy a car, we will pay attention to all aspects of this model in advance, especially the posts and word-of-mouth posted by car owners in major forums and vertical websites. Apart from the navy, there are still some car owners’ real car experience that is worth learning. Let’s take a look at the word-of-mouth score of BYD Qin plus DM-I. The comprehensive score of BYD Qin PLUS DM-i is 4.75, and the result is not bad, so BYD Qin PLUS DM-i can be considered.

If you have seen the above, you still have doubts about whether BYD Qin PLUS DM-i is worth buying, then you can also look at the performance of competing products of BYD Qin Plus DM-I. Among the following competing products, the Roewe ei6 MAX sold the most last month, with 662 cars. There is always one car for you.

If the price of Qin PLUS DM-i is suitable recently, then friends will hurry! Linkage promotion in many places across the country, and there are even more discount models as low as 30%.

　　Look at the goods in the WeChat group, place orders in small programs, and move your fingers, and all kinds of fresh, grain and oil products will be delivered to your home. In 2020, a sudden epidemic disrupted everyone’s life rhythm, the online retail format broke out, and the community group purchase accident became an important support for the residents’ lives, and giants such as Meituan, Ali, JD.COM and Pinduoduo entered the market one after another. Recently, a reporter from Qilu Evening News and Qilu Yi went into several communities in the provincial capital to understand the current situation of community group buying.

　　Qilu Evening News Qilu Yidian reporter Yu Yuxing

　　Daily sales of 70-80 orders

　　The maximum turnover per day is more than 10,000 yuan.

　　Near eleven o’clock in the evening, Ms. Zhou "poisoned late at night" in the WeChat group, and photos and videos of spicy crayfish teased everyone’s appetite. The "Ding Ding" mobile phone kept shaking, and Ms. Zhou harvested another wave of orders before going to bed.

　　In the past four years, Ms. Zhou has been a well-known "group leader" of a residential district in tianqiao district, Jinan, with two WeChat group purchases of 500 people. "In 2017, we started to do community group buying, and the users are basically the owners of the community." Ms. Zhou’s community group purchase relies on her own express collection point, and it is convenient for owners to take home the fresh food they bought the day before when they take the express delivery. "The source of customers is relatively stable, and it is not so laborious to do it. It is like opening another online supermarket. Everyone orders online and picks up the goods the next day. I am a pick-up point here."

　　It is reported that there are thousands of households in Ms. Zhou’s community, and there are several community group purchases like her. "Basically, some treasure moms and mom-and-pop shops are doing it, and the user cross is very large." Ms. Zhou said that the platforms of the heads of delegations also cover each other, including Prosperity Optimization, Ten Clubs, You, Me and You. "I will send products from all platforms to the group and let users choose. Recently, a beautiful group was selected, and the activity was relatively strong, which was very popular with everyone. "　

　　There are also differences in the opening of the group on each platform. Some groups are held every day, while others are held every other day. "Every time you open a group, you can trade dozens of orders and hundreds of orders. Each platform adds one, and the average is seventy or eighty orders a day." Ms. Zhou said that because most of them are fresh, grain and oil products, the single-day trading volume fluctuates greatly. "As little as two or three thousand yuan, more than ten thousand yuan. Especially on holidays, the volume of fruit gift boxes is very large, and the single-day turnover can reach about 13 thousand yuan. "

　　10%-15% commission

　　The "head" has a considerable monthly income.

　　The second day after the rally, Ms. Zhou was the busiest time, basically from morning till night. "Especially after work, users go home and take the food back. There are often long pick-up queues at the door of the store. "

　　Ms. Zhang, a working mother, is a member of the daily queue to pick up the goods. "If there is no food at home, just visit the group buying group in the community to see what to buy, and send it to the community the next day. It is simply too convenient to visit the vegetable market and supermarket." In Ms. Zhang’s view, convenience is the main reason for choosing community group buying.

　　In addition to convenience, good quality and low price are also a major reason why community group buying can be a big fire. Ms. Zhou takes mangosteen, kiwi fruit, pitaya and other fruits on her platform as examples. Mangosteen, which costs more than ten yuan a catty in the supermarket, only needs 8.9 yuan to buy in the platform. 9.8 yuan in Xuxiang Kiwifruit Platform weighs three kilos, and the cheapest Kiwifruit in the supermarket also costs five or six yuan a kilo.

　　"The quality of fruits and vegetables is comparable to that of supermarkets or even fresher, and the price is still cheap. Users who have bought them will place orders again and again." Ms. Zhou said that word-of-mouth communication among community users is more reliable than any advertisement. After being recognized by users, everyone will pull acquaintances in to buy together.

　　It has been less than half a year since Ms. Feng, the "post-90 s" Bao Ma, became the "head" of community group buying. "My girlfriend recommended me to join, just to earn pocket money while taking care of my children." Ms. Feng said that there are more than 200 people in her group, and the daily sales are around 1,000 yuan. The platform gives 10% commission, and it can also have two or three thousand yuan a month.

　　Ms. Zhou, who has two 500 people in her hand, has to double her monthly income. "There are many platforms, and the commission is basically between 10% and 15%." Ms. Zhou said that the monthly income is basically stable at around seven or eight thousand yuan. "On holidays, with the gift box, the monthly income is around 10,000 yuan."

　　After seizing the market

　　Doing a good job in product service is the key.

　　Ms. Li, who has been the head of the Tenth Club in Dianliu Community of Jinan for more than two years, was recently invited by the US delegation and became the preferred head of the US delegation.

　　"For the head of the team, multiple platform products can be sent to the same group, so that users can make their own judgments and place orders." Mr. Yuan, the preferred promoter of Meituan, said that Meituan had developed more than 3,700 WeChat groups with more than 100 people in Jinan in one and a half months.

　　Different from the "seed player" such as the Tenth Club, which developed from the grassroots level of the industry, Meituan is a key project of large enterprises with a level of 100 billion. With strong financial support, it can be quickly opened nationwide at the beginning of the opening. "In the next step, relying on Meituan APP, Meituan Optimization will be made into a new industrial line alongside Meituan Takeaway."

　　In Mr. Yuan’s view, there is an essential difference between the optimization of the US Mission and the Tenth Mission. The two modes are different. The Tenth Mission has small profits but quick turnover, focusing on profit and demanding sales; Meituan pays more attention to the number of orders when buying food, and wants to make data.

　　However, Mr. Yuan admits that, as far as Jinan is concerned, the order quantity of the Tenth Club is currently unmatched by the US Mission.

　　However, the US Mission also has an advantage that the Tenth Mission does not have, that is, the US Mission APP. "At present, Meituan has been connected with Meituan APP, and everyone can place an order through Meituan APP, which means that all people who have Meituan APP may become the preferred users of Meituan."

　　"Community group buying starts from the head of the team, but it will eventually end in the supply chain". In fact, how to do a good job in product service after seizing the market is the most critical part for community group buying platforms such as Meituan Optimization, Ten-Club Group, and City Life.

　　Hot money poured in, and giants followed suit.

　　Is community group buying "really fragrant"

　　If you win fresh food, you win the world. In recent years, various sales models of fresh food industry have been favored by capital giants frequently. In 2020, as a "pre-sale+self-promotion" sales model in the fresh food industry, community group buying became popular overnight and was selected by the capital again under the influence of the epidemic.

　　According to the data of Tianyancha, according to incomplete statistics, there have been more than ten times of financing in the field of community group buying and fresh e-commerce in China this year, amounting to 10 billion yuan. Among them, the 10th Club was voted for three times this year, with a total financing of US$ 249.7 million; Tongcheng Life received 200 million dollars and tens of millions of dollars in financing in June and July. According to LatePost, the latest round of financing of $495 million per day is the largest financing of fresh food industry to date.

　　With the influx of hot money and the follow-up of giants, what is the future of community group buying?

　　"Community group buying adopts ‘ Pre-sale+self-withdrawal ’ The model is based on sales, there is no turnover, there is no need for offline stores, and there is no high distribution cost for centralized self-lifting. " Ms. Zhou, who has worked hard in community group buying for three or four years, is very optimistic about "community group buying". She said that the pre-sale method of community group buying can effectively reduce the inventory, and the goods have been booked and sold before they arrive in the warehouse, which improves the turnover efficiency and reduces the product loss rate and distribution cost.

　　However, Mr. Zhao, a veteran in the industry, pointed out that the so-called fixed production by sales and fixed production by demand is actually difficult to achieve. Moreover, domestic agricultural products are generally lack of standardization, and direct mining in the place of origin and taking goods at the base are mostly gimmicks. "Community group buying also requires multiple categories, which is difficult for most enterprises, and many still rely on the local first-class wholesale market."

　　In addition, Mr. Zhao believes that how to keep the head of the platform and keep the tourists is also a problem worth exploring.

　　It is foreseeable that the competition for community group buying resources is bound to intensify. With the entry of Internet giants, there are more possibilities for this track.

According to Yu Chengdong, the chairman of BU, from September 12th to October 6th, the cumulative order for this car exceeded 50,000 units. In addition, at the new product launch conference of Huawei’s autumn scene held on September 25th, it was confirmed that the M9 will be officially launched in December 2023.

　　It is pointed out that Huawei is behind the hot sale of the new M7.The effect of the strategic layout of the automobile industry has been continuously verified intuitively. The new M7 in Wenjie has been upgraded in many aspects, such as HarmonyOS cockpit 3.0, Huawei ADS2.0 and high-standard active and passive safety systems, while the starting price has been reduced, and the product strength and cost performance have been significantly improved. With the market recognition of Huawei’s self-driving car model, investment opportunities in the industrial chain are expected to emerge continuously, and Huawei’s smart cabin and smart driving fields will fully benefit.

　　Previously, it was pointed out that in addition to M7, M9 also appeared in the 375th batch of Road Motor Vehicle Manufacturers and Products of the Ministry of Industry and Information Technology recently."in. "With the continuous release of M7 orders and the expectation that the new model M9 will be launched soon, we will focus on the opportunities of Huawei’s automobile industry chain."

Recently, with the sharp drop in the national temperature, the old problem that the battery life of electric vehicles has been greatly reduced has begun to appear again, and it has been denounced by the people all over the country on the Internet, involving almost all electric vehicle brands, especially Wuling, MODEL3 and Han, which are in the front row of sales.

Among the numerous crusades, there is a Shanxi netizen whose net name is "Handsome Brother". He broke the news that he bought the Han EV with a long battery life of one and a half months, and only ran for 230 kilometers from full charge to 5% left, which was nearly two-thirds less than the battery life of 605 kilometers.

Judging from the screenshot of the post, the post has a lot of traffic, with 352 likes and 1044 comments. Many people think that the attenuation of power battery actually reaches 62%. The author also thinks this data is incredible. After reading many articles, many people have got the concept wrong.

The author has been focusing on new energy vehicles for many years, and is very aware of the three killers that affect the battery life: battery attenuation, low-temperature activity of batteries, and high power consumption of heating and air conditioning. The battery life of a series of well-known electric vehicles that have been exposed recently is actually caused by the joint action of the three.

First, battery attenuation:

At present, the technology of power battery is very mature, and the attenuation of battery in normal use is actually very low. As long as it is used according to the instructions, the natural attenuation of battery is within the controllable range, and it can almost be used for vehicle scrapping.

Second, the low-temperature activity of the battery is reduced:

The research data show that at 0℃, the capacity of Ferrous lithium phosphate power battery is only 88% of that at 25℃, which is 12% lower. The reason is that power batteries are basically lithium-ion batteries, and the activity of lithium-ion will decrease at low temperature, and the lower the temperature, the lower the activity.

Third, heating and air conditioning power consumption:

Electric vehicles run on power batteries. Apart from the controllable attenuation and activity reduction, the power consumption of heating and air conditioning can be said to be the biggest culprit in reducing the battery life of electric vehicles. Taking the actual measurement by netizens as an example, Han EV heating and air conditioning is used at about 0 degrees, about 4KW/ hour for the first hour and about 2KW/ hour for continuous use.

Understand the above concepts, and then look at the use of Han EV of Shanxi car owner "handsome brother", which is easy to understand.

Some media reported that the owner used heating and air conditioning when driving. This is understandable. In November, the average daily temperature in Shanxi is about 5 degrees. If you don’t turn on the air conditioner, your hands will be stiff.

There is another detail in the post of "Handsome Brother": "I took the car with full electricity at the end of October, and now I have rushed twice, driving a total of 744 kilometers. After reading the posting time, on November 27, everyone should understand.

According to the owner, he charged the battery three times in a month or so, with a total journey of 744 kilometers and an average battery life of 248 kilometers, which is really consistent with the last time he said that he only ran 230 kilometers.

However, I noticed another data: "handsome brother" traveled 744 kilometers a month, with an average of 24.8 kilometers a day. This data is not high, which represents the daily driving of the vast majority of car owners and is basically equivalent to the average daily driving of passenger car owners in China.

So low, judging that "handsome brother" should be an office worker, he goes to and from work every day, four times a day, driving for several kilometers at a time, and 80% is driving in the urban area.

According to the normal driving speed in urban areas, the average speed will generally not exceed 20km/h, that is to say, "Handsome Brother" ran 744km after three times of charging, and the driving time may be as high as 37 hours or more. According to the heating data of Han air conditioner provided by netizens, in the first hour, it consumes about 4KW per hour, and if it keeps driving, it consumes about 2KW/ per hour later.

"Handsome brother" always travels only 24.8 kilometers every day, and the air conditioner will not be turned on for a long time every time, that is, it is in the most power-consuming interval, 4KW/ hour.

The battery life of electric vehicles is calculated by the time, but the air conditioner is not calculated by the time. Han runs 230 kilometers with a full charge of 76KW, and it takes about 9 hours to run in the short distance in urban areas. Only the air conditioner consumes electricity, it will use up 36KW, and then subtract 5% of the battery balance of about 4KW, leaving 36KW for driving. According to the proportional calculation, the normal battery life should be about 286 km.

Because the heating and air conditioning use a lot of electricity, the battery life for real driving is only about 286 kilometers, and then the battery activity is reduced by 12% at a low temperature of about 0 degrees, which is about 250 kilometers, which is basically consistent with the actual measurement of "handsome brother".

At this point, the truth is clear. Whether it is Han EV, MODEL3 or Wuling, the reason why the measured battery life is more than half is not the battery attenuation or the battery activity reduction, but the hot air conditioner is turned on.

Write at the end:

The author has been paying attention to new energy vehicles for many years, and sincerely advises consumers who are going to buy cars. If you don’t have fixed parking spaces and charging piles, it is really not recommended to buy electric vehicles, even for the sake of licenses! If you insist on it, first of all, you will be unhappy and full of complaints. Secondly, it is also a negative harm to the development of new energy vehicles, harming others and yourself.

For car owners with fixed parking spaces and charging piles, it is not a big problem that the battery life is greatly reduced by turning on the air conditioner in winter. After all, the current electric car has a battery life of 500 to 600 kilometers. Even if the air conditioner is turned on all the time, the battery life is enough for most people.

In fact, if you have a fixed parking space and a charging pile, park your car in the garage every night, hang up the charging pile and go home to sleep. This is the correct way to turn on the electric car. If you are used to it, it is really more convenient than refueling. It takes a lot of time to go back and forth to the gas station. Under the current situation of urban traffic jams.

　 　 　 　　It’s the National Day holiday soon. Coincidentally, this year’s National Day and Mid-Autumn Festival collided, and there was an 8-day holiday. I believe many friends have already made travel plans for this small holiday. However, it is inevitable that high-speed rail and plane tickets will be hard to find every time there is a small holiday. In contrast, go on road trip is a good choice. You can enjoy the travel time and enjoy the driving pleasure. Why not? So when it comes to go on road trip, it is very important to choose a suitable car. Today, I want to talk about the M5 Smart Driving Edition in the world, which is a good "God Car" in go on road trip, and has captured the hearts of many consumers with its "double smart ceiling" and high performance. Don’t believe it? Let’s continue to look down.

Travel is worry-free and convenient, and HUAWEI ADS 2.0 gives strength.

For drivers who don’t often drive at high speed, how to safely merge from the ramp into the main road with dense traffic is a great "test". In view of this, HUAWEI ADS 2.0 equipped with the M5 Intelligent Driving Edition has quite powerful functions. It can help car owners to import and export high-speed ramps independently, with a success rate of 98.86%, and its reliability is comparable to that of skilled and experienced "old drivers".

Many people still don’t park their cars after learning their driver’s licenses. Even with the reversing radar or panoramic images, novice drivers still feel a headache. Don’t panic, the M5 Smart Driving Edition helps novice drivers in all directions, and naturally it won’t ignore the parking problem. Wenjie M5 Intelligent Driving Edition can learn independently in the garage environment and build 3D models. After parking in a fixed parking space once, it can enter the parking lot again, and then activate the valet parking assistance function to cruise to the target parking space for parking and warehousing. Based on the multi-sensor fusion perception of lidar+camera+ultrasonic radar+millimeter wave radar, Wenjie M5 Intelligent Driving Edition has "the strongest intelligent parking on the surface", which supports parking in conventional vertical, horizontal, oblique and spatial parking spaces, and supports various complex special-shaped parking spaces such as broken roads and extremely narrow parking spaces. The parking success rate is as high as 95%. From then on, novice Xiaobai can easily park in the warehouse.

HarmonyOS Smart Cockpit 3.0 is not only smart but also useful.

It is inevitable that the driver needs to be replaced when traveling for a long time, but once replaced, the seat needs to be readjusted, which is very inconvenient. However, this problem is perfectly avoided in the M5 version. Through the human eye positioning algorithm, Wujie M5 Intelligent Driving Edition is the first in the industry to realize the adaptive adjustment of HUD height. After sitting, you can quickly adjust the HUD to the optimal height, making driving safer and more convenient.

On the other hand, the addition of the rear HUAWEI MagLink magic suction car interface opens up more possibilities and scenarios for users in the car. Passengers in the front and rear rows can have meetings and share content easily, while the front row can also push the content to the back row. Let the M5 Intelligent Driving Edition in the asking world easily become the exclusive study, game hall or meeting room for users.

In fact, a good car that is praised by people will always have inexhaustible advantages. In addition to "double intelligence", the performance is also quite interesting. Wenjie M5 Intelligent Driving Edition adopts an all-aluminum chassis unique to millions of luxury cars, which makes the vehicle roll smaller and have greater rigidity, thus improving the handling performance and safety performance. Combined with the front double wishbone+rear multi-link independent suspension, the Wujie M5 intelligent driving version can maintain stability under different driving conditions, effectively prevent roll, and improve driving confidence and ride comfort.

It is worth mentioning that the HarmonyOS intelligent cockpit has also been applied in the M5 standard edition. In addition, the car also has the advantages of long battery life and intelligent extended range technology. It is a good car with a good price-to-price ratio, and it is another good choice at the same level.

With all-round leading intelligent configuration, Wenjie M5 Smart Driving Edition can definitely become the best choice for many young consumers who buy cars for the first time. At the same time, thanks for giving back to the old users’ rights and interests, the community will open a new era of smart travel with super ability and sincerity, and old users can enjoy 15,000 yuan of HUAWEI ADS 2.0 urban smart driving pilot NCA deduction rights and interests.

If you happen to be very interested in the M5 Smart Driving Edition, I suggest you go to the 4S shop to experience this car, and I believe there will be a surprise experience.
