The power exchange mode is to replace the batteries of new energy vehicles to meet the endurance needs of owners. It is a mode of separating the vehicle and the battery for energy supplement. Different from the charging mode of the charging pile, the power exchange mode can greatly save the energy replenishment time of the vehicle owner. In terms of security, power exchange has certain advantages over charging. In addition, the power exchange mode can also effectively alleviate the load of the power grid. According to the statistics of the Ministry of public security, by the end of June 2022, the number of new energy vehicles in China had reached 10.01 million. It is estimated that by the end of the 14th five year plan, the number of new energy vehicles in China will exceed 20 million. With the gradual increase of the number of new energy vehicles, it is difficult to meet the energy supplement demand of the new energy vehicle market only by charging. The power exchange mode will become a new track for the energy supplement of new energy vehicles. At present, what is the development of the new energy vehicle power exchange mode in China? Can accelerating the construction of the power exchange system effectively alleviate the unbalanced charging of new energy vehicles? The reporter of science and technology daily interviewed many experts on this. The power exchange mode is at the "emerging" stage, which is different from the previous charging mode of the whole vehicle. The power exchange mode is to replace the batteries of new energy vehicles to meet the endurance needs of owners. It is a mode of separating the vehicle and the battery for energy supplement. At present, there are two technical routes for power replacement: one is the whole package power replacement, that is, the battery pack at the bottom of the car is replaced as a whole, and the standards of battery packs for different models are different; The other is to change power by box, that is, to design standardized and detachable power battery boxes, and arrange different numbers of power battery boxes at the bottom of the vehicle according to the needs of different models. When changing power, you only need to change the power battery boxes. In recent years, as a new energy supplement mode of new energy vehicles, the power exchange mode has not only attracted widespread attention from the industry, but also received strong support from national policies. The 2020 government work report clearly included the power exchange station in the scope of China's new infrastructure projects. In October of the same year, the general office of the State Council issued the "on printing and distributing the development plan of the new energy automobile industry (2021-2035)", which clearly encouraged the promotion and application of the power exchange mode. The 2021 government work report once again proposed to increase parking lots, charging piles, power stations and other facilities, and accelerate the construction of a power battery recycling system. In January this year, the national development and Reform Commission and other departments jointly issued the implementation opinions on further improving the service guarantee capacity of electric vehicle charging infrastructure, which further proposed to accelerate the promotion and application of power exchange mode, strengthen the innovation and standard support of charging and exchange technology, optimize and improve shared power exchange services, and improve the safety, reliability and economy of power exchange mode. According to the Research Report on China's new energy vehicle power exchange market released by iResearch consulting, by the end of 2021, China had built about 1406 new energy vehicle power exchange stations, a year-on-year increase of 1.5 times. It is expected that the total number of domestic power exchange stations will exceed 30000 by 2025. The power exchange mode is at the stage of "emerging". "The current power exchange mode has just started, and there is still a lot of room for development in the future." Tong zongqi, director of the Information Department of China electric vehicle charging infrastructure promotion alliance, pointed out. The introduction of a series of policies has enabled the industry and enterprises to
