Everyone is talking about 1000 km or more < a target ="_ blank" href=" https://news.163.com/news/search?keyword=%E7%BB%AD%E8%88%AA "> battery with < / a > endurance. But have you ever asked about user experience? How many users are really willing to drive on the road with 1000 kilometers of batteries? Have you ever asked when the technology will be realized? If it is two or three years later that we can achieve 1000 km endurance, then perhaps the layout of charging piles will be more perfect, and the problems of power change mode and fast charging mode have been solved. Do we still need cars to run around with 1000 km batteries? " On January 19, at the mass production conference of Weima Apollo cloud driverless car, the founder of Weima automobile < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E6%B2%88%E6%99%96 "> Shen Hui < / a > said publicly. < / P > < p > it is understood that in the past week, Weilai, SAIC Zhiji and GAC AIAN successively announced that they will launch pure electric vehicles with a driving range of more than 1000 km_ blank" href=" https://news.163.com/news/search?keyword=%E7%9F%B3%E5%A2%A8%E7%83%AF "> graphene < / a > based battery technology has caused great controversy in the industry. < / P > < p > "what is graphene? What is graphene base? What is a real solid state battery? Generally speaking, core hardware cooperates with suppliers. All suppliers of 1000 km batteries and solid-state batteries have been in contact with each other for two or three years. It will not take a few months for any car factory to cooperate with battery suppliers. We will all have these technologies, and they will not form a very big technical barrier. " Shen Hui believes that the real technical barrier lies in software. For example, in < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E8%87%AA%E5%8A%A8%E9%A9%BE%E9%A9%B6 "> automatic driving < / a >, in algorithm. In Shen Hui's opinion, whether it's autonomous driving, unmanned driving or driving range, it's more practical to deliver the core technologies that users need than to draw a big pie. < / P > < p > "regardless of technology, we still need to ask how many users really need a 1000 km battery, or whether they want to make a 1000 km battery when the charging facilities and power exchange facilities are perfect in the next two or three years. This is the real direction of making products and technology." Shen Hui pointed out that if mainstream models are equipped with 1000 km battery, it will be a huge waste of social resources. < / P > < p > "in the future, it is necessary to configure models with different driving range according to different users and specific infrastructure construction." Shen Hui finally said, "more important than mileage is the efficiency per kilowatt hour and the actual energy consumption. Efficiency is more important." < / P > < p > (author: Du qiaomei, editor: He Fang) < / P > < p >
