Battery management system is conducive to maintaining excellent performances and safety of the vehicle power batteries, which is able to conduct functions of state estimation, energy equalization, thermal management and fault diagnosis. However, the traditional vehicle-end facility cannot meet the demands on hash rate and communication for advanced BMS. This paper proposes a cloud battery management system based on CHAIN (Cyber Hierarchy And Interactional Network), which can realize vehicle-cloud cooperation through End-Edge-Cloud-Intelligence mode and solve the problems of hash rate in distributed computation framework. It has the ability to provide different service delivery modes, including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS) and Data as a Service (DaaS). At last, several technical challenges and issues are concluded and an outlook on the multi-scenario applications of CHAIN is presented.
