Since late November, several cities including Chongqing, Wuhan, Baotou, and Xuzhou have launched demonstration projects for battery swap operation of new energy vehicles (NEVs). From next year, cabs and dump logistics vehicles using the battery swap model are expected to be introduced to the market.
At present, the pilot areas of China's new energy vehicle battery swap model are Hainan and Beijing. Recently, other non-pilot regions are also taking active actions.
On November 26, a signing ceremony for a strategic cooperation agreement between Dongfeng Motor Group and State Grid was held in Wuhan, where the two will work together to launch a new business based on the battery swap model.
In November, Chongqing Expressway Group and Geely Technology Group signed a cooperation agreement, and the first battery swap demonstration stations of Geely will be located in Chongqing high-speed service areas, and the first battery swap demonstration station is expected to start construction in the near future.
On December 9, Baotou City launched the new energy vehicle battery swap project, which includes a fully automatic battery swap station, manual battery swap station and mini-community battery swap station.
Driven by the development of the battery swap model of new energy vehicles, buses, cabs, urban logistics vehicles, and sanitation and cleaning vehicles in Baotou will be further electrified.
Shanghai Securities News quoted industry insiders as saying that the main reason for the recent rapid popularity of battery swap mode in various places is technological progress. With the rapid development of domestic battery technology in recent years, the battery swap model has gradually gained the trust of society and is expected to launch a unified standard.
Cars are very optimistic about the future of battery swap service model. Botann Technology Chairman Nie Liang believes that charging is like using a landline phone, although it will still exist the use of scenarios will be reduced. And battery swap is like using a cell phone, more and more users will choose it in the future.
In China’s passenger car market, NIO is the most high-profile promoter of the battery swap model. In August, the EV maker released its highly expected BaaS (Battery as a Service) battery rental service in China and generated high interest in China's auto and technology circles.
For a long time, the power battery, especially the single-cell specification size is not uniform, has been a major obstacle to the development of the battery swap model.
At present, China's new energy vehicle battery swap mode is mainly used in the field of public transportation, such as battery swap bus and battery swap taxi.
In August, a recommended national standard for electric vehicle battery swap safety requirements led by NIO, the Beijing Electric Vehicle Co., Ltd. (BJEV) which is a subsidiary of the BAIC Group, and China Automotive Technology and Research Center, passed the review by the National Technical Committee of Auto Standardization.
The move will provide guidance for the development of electric vehicles with battery swap mode.
The standard takes the whole car, battery swap system, battery pack, battery swap mechanism, battery swap interface, and other key elements as the object of research.
