Recently, there is a very attractive news that Xiaopeng P7's NEDC has a maximum endurance of 706km, surpassing the 668km of the model 3's long endurance rear drive version, and has become the longest NEDC intelligent vehicle in China so far. As soon as the news came out, many people in the automotive industry were very excited, thinking that pure electric vehicles can finally compete with traditional fuel vehicles in terms of endurance, and the era of pure electric vehicles becoming the mainstream will soon come. However, the car buyer believes that if the following problems are not solved, then pure electric vehicles will become the mainstream, I'm afraid it will have to wait. The attenuation problem remains to be solved. We all know that the endurance is the key factor restricting the development of pure electric vehicles, but if the purpose of vehicles is limited to daily steps, in fact, most of the electric vehicles now can already meet. So, why do people seldom choose electric cars even for commuting? The answer to this problem is that the problem of battery attenuation is still unsolved. For most people, a car is a product with a long replacement cycle. Unlike a mobile phone, it can be replaced in a year or two. However, in today's battery technology, the longer the electric vehicle is used, the shorter the endurance will be with the battery attenuation, resulting in a sharp deterioration of the car experience. Of course, you can also replace the battery pack to get the same endurance experience as when you first bought it, but it is difficult to reach the standard of free replacement. In fact, as a member of the new force of car building, there was a "2020 G3 listing storm" in 2019. It can be seen from this that there is still a lot of room for improvement in the after-sales service of Xiaopeng automobile. Therefore, more efforts and kindness are needed to make consumers satisfied with their battery guarantee scheme. In addition, if the 706km of Xiaopeng P7 subtracts the endurance reduction caused by the actual endurance difference in use and the battery attenuation, the actual range that can be achieved is not as high as expected, so if you want to replace the fuel vehicle, you need to continue to increase the endurance. Combined with the above two points, we can see that the endurance mileage of Xiaopeng P7 is not as good as expected. If you want to achieve hot sales, the first thing you need to solve is the battery guarantee problem, which is also applicable to other new energy vehicle enterprises. Apart from battery attenuation, consumers seldom buy cars, which has a lot to do with poor safety. At present, the mainstream automotive batteries are lithium iron phosphate battery and lithium-ion ternary battery. Among them, lithium-ion ternary battery has become the mainstream of pure electric vehicle energy storage battery because of its high energy density, which can significantly improve the range of pure electric vehicle. However, the self ignition temperature of the ternary lithium-ion battery is 200 ℃, and that of the lithium phosphate battery is 500-800 ℃, so the safety of the ternary lithium-ion battery is not as good as that of the lithium iron phosphate battery. That's why it's easier for us to see the auto ignition of models equipped with ternary lithium-ion batteries. According to the information released by the Ministry of industry and information technology, Xiaopeng P7 also uses the ternary lithium-ion power battery, and the energy density of the battery system has reached 170wh / kg, which shows that Xiaopeng automobile needs to spend more efforts to ensure the safety of the whole vehicle in the collision process. However, at present, Tesla is unable to ensure that its own vehicle will not ignite in a collision. It can be seen how difficult it is for Xiao Peng, who has little experience in car building, to ensure that everything is safe. If Xiaopeng can't do it, then it's very difficult for Xiaopeng P7 to sell well and break everyone's stereotype of pure electric vehicles. When the price of pure electric vehicle is still too high, the price of vehicle often plays a decisive role. Therefore, even if the pure electric vehicle does not have battery attenuation, safety and other issues, it is difficult to compete with the traditional fuel vehicles, because in terms of price, the pure electric vehicle currently has few advantages. In fact, before the launch of Xiaopeng P7, which has a endurance of 706km, Tesla has already created a model 3 long endurance rear drive version with similar endurance mileage, and its NEDC endurance mileage has reached 664km. But even so, it still doesn't sell well all over the world. Why? The car buyer thinks it has a lot to do with its official price of 421000 yuan. Although the pre-sale price of Xiaopeng P7 is 24.00-370000 yuan, which is much cheaper than Tesla's domestic model 3, it is still higher for a fuel oil. In addition, the model of Xiaopeng P7 with a pre-sale price of 240000 yuan refers to the long-range rear drive, with a NEDC range of 550 + km. If you want to buy 706km version, it will cost about 300000 yuan. Imagine, who would easily take out 300000 yuan to buy an autonomous pure electric car with not so strong brand power and not yet proven quality? It is estimated that the local tyrants are the only ones. In addition to the endurance, the battery attenuation, poor safety and high price are also the key factors restricting the development of pure electric vehicles. If Xiaopeng P7 can't improve these, it's just wishful thinking to fundamentally change the status quo of pure electric vehicles. Of course, it is no problem to improve the endurance and promote the sales growth of the brand.
