A charging protection system, a rail vehicle and a charging system, the charging protection system comprising: a vehicle control unit for sending a charging command; the first battery management controller receives, forwards and responds to the charging command so as to control the charging anode contactor and the charging cathode contactor to be attracted; the second battery management controller receives and responds to the charging command forwarded by the first battery management controller so as to control the battery contactor to be closed; the first battery management controller is further used for controlling the charging anode contactor and the charging cathode contactor to be disconnected after determining that the battery reaches a full charging condition; and/or the second battery management controller is also used for controlling the battery contactor to be switched off after determining that the battery is fully charged. According to the system, the situation that a single battery management controller or a contactor breaks down and cannot be disconnected, so that the battery is overcharged is avoided, and the safety redundancy of the system is improved.

    一种充电保护系统、轨道车辆和充电系统,该充电保护系统包括:整车控制单元,用于发送充电命令;第一电池管理控制器,接收、转发并响应充电命令,以控制充电正极接触器和充电负极接触器吸合;第二电池管理控制器,接收并响应第一电池管理控制器转发的充电命令,以控制电池接触器吸合;第一电池管理控制器还用于:确定电池达到充满条件后,控制充电正极接触器和充电负极接触器断开;和/或,第二电池管理控制器还用于:确定电池达到充满条件后,控制电池接触器断开。该系统避免了单一电池管理控制器或接触器发生故障,无法断开而导致电池过充,提高了系统的安全冗余。
