The invention provides a battery management system with a redundancy function. The system comprises a battery management system in communication connection with a whole vehicle microcomputer system, the battery management system comprises a redundancy setting battery management system A and a redundancy setting battery management system B. A main control module A of the battery management system Aand a main control module B of the battery management system B are respectively connected with battery system submodules through at least one CAN bus to form a double-branch redundancy battery management system. The invention further provides a redundancy management method and a power-on and power-off management method of the battery management system. When one branch battery system or the BMS fails and cannot be used, the other branch BMS and the battery system work normally, energy is continuously provided for the whole vehicle, and the safety and reliability of the whole vehicle are improved.

    本发明提供了一种具有冗余功能的电池管理系统,包括与整车微机系统通信连接的电池管理系统,所述电池管理系统包括冗余设置电池管理系统A和电池管理系统B,电池管理系统A的主控模块A和电池管理系统B的主控模块B分别通过至少一路CAN总线连接电池系统子模块,形成双支路冗余电池管理系统。本发明还提供了该电池管理系统的冗余管理方法、上下电管理方法。本发明能在一支路电池系统或BMS出现故障无法使用时,另一支路BMS及电池系统正常工作,为整车持续提供能源,提高整车安全性及可靠性。
