China’s battery swap-enabled models are expected to see further development as an industry association begins seeking comments on a draft technical standard led by entities including NIO.
The China Association of Automobile Manufacturers (CAAM) on Tuesday released on its website a draft of a group standard for the construction of shared battery swap stations for electric passenger cars, signaling that the previously criticized lack of standards in the field is expected to ease at an accelerated pace.
The CAAM released a total of 15 documents, covering technical requirements for battery swap platforms and devices, communication protocol requirements for battery packs, technical requirements for battery packs, technical requirements for liquid-cooled connectors, technical requirements for battery storage systems, and planning and layout requirements for battery swap stations.
The CAAM said that the standard aims to realize the sharing of battery swap platforms and even battery swap devices and to achieve preliminary data access and interconnection.
The standard hopes to promote battery swap mode toward more convenience and safety, scale development and further cost reduction from the perspective of vehicle, battery pack and battery swap device linkage, the CAAM said.
The entities involved in drafting the technical standard include Beijing Jiaotong University, NIO, Beijing Electric Vehicle Co Ltd, and public battery swap station operator Aulton.
