Promote the release of norms and standards for the sharing of power exchange stations for electric passenger cars.

China Quality News Network (Zhang Yang) Recently, China Association of Automobile Manufacturers announced that 15 group standards, such as "Code for the Construction of Shared Substations for Electric Passenger Cars Part I: General Provisions", have been compiled according to the prescribed procedures of "Administrative Measures for the Revision of Standards of China Association of Automobile Manufacturers (Trial Edition)". It was audited by China Automobile Industry Association and officially released on December 20th, 2021. The release of this series of group standards will better promote the development of the electric vehicle industry.

The picture is from the website of China Automobile Industry Association.

The research and formulation of this series of standards lasted for nearly two years, and the relevant units and industry experts conducted many discussions and conducted extensive research work, which was strongly supported by relevant automobile companies, power battery manufacturers and other units, and obtained a large number of constructive suggestions and test data, ensuring the quality of standard preparation. The publication of this series of group standards not only specifies the key core components, technical requirements and general processes of the shared power exchange station for electric passenger cars, but also classifies, standardizes and requires the quick exchange device, communication protocol, locking mechanism, data management, test rules and safety protection.

According to the China Automobile Association, the power exchange mode of electric vehicles not only meets the requirements of promoting the innovation of electric vehicle models, but also solves the difficult problems in the popularization of electric vehicles, bringing new choices and experiences for users’ green and smart travel. Therefore, the publication of the series of group standards of "Code for the Construction of Shared Substations for Electric Passenger Cars" can better promote the development of the electric vehicle industry. The release of this series of group standards will give full play to the characteristics of strong flexibility and wide participation of group standards, and continuously and widely accept the opinions and suggestions fed back by industry units through various channels during the implementation process, and revise them in time to better serve the promotion and application of power exchange mode.

In 2020, the "Government Work Report" included the construction of power exchange station in the scope of new infrastructure construction for the first time, and the policy began to encourage the application of power exchange mode. Since then, more and more mainstream car companies have begun to join the camp of power exchange mode. Among them, Weilai Automobile, Beiqi New Energy, SAIC, Geely Automobile, Guangzhou Automobile Group, etc. have all introduced models of power-changing mode.

However, there is a gap between the vehicle technology and battery standards of various enterprises, and there is a lack of unified industry standards, so there are also great differences in the construction standards of power exchange stations, which leads to many difficulties in sharing power exchange stations.

With the publication and promotion of the series of group standards of "Code for the Construction of Shared Substation for Electric Passenger Cars", the shared substation will gather various power exchange requirements of different brands and models, integrate and unify the scattered power exchange stations, and exert the potential of a single substation to a greater extent without changing the total number of constructions.
