The invention discloses a train and a battery pack electric quantity balance control method and system thereof, a whole vehicle controller and a battery management system. The method comprises the steps that the state of charge SOC of a battery pack in each compartment is obtained; when it is determined that the BMS of all the carriages sends a carriage high-voltage power-on instruction and it is determined that the BMS of all the carriages is subjected to high-voltage power-on successfully, an auxiliary power-on instruction is sent to the BMS of the carriage with the maximum SOC, and the auxiliary power-on instruction is used for indicating the battery pack in the carriage with the maximum SOC to supply power to auxiliary loads in all the carriages; and when an auxiliary power-on success signal sent by the BMS of the carriage with the maximum SOC is received, auxiliary loads in all the carriages are controlled to work. According to the control method, the battery pack with the maximum SOC supplies power to the auxiliary loads in all the carriages, so that the electric quantity of the battery pack with the maximum SOC is quickly consumed, and electric quantity balance of the battery pack of the whole vehicle is achieved.

    本发明公开了一种列车及其电池包电量均衡控制方法和系统、整车控制器、电池管理系统,所述方法包括:获取每节车厢中电池包的荷电状态SOC;在确定所有车厢的电池管理系统BMS发送车厢高压上电指令,并在确定所有车厢的BMS均高压上电成功时,向SOC最大的车厢的BMS发送辅助上电指令,其中,辅助上电指令用于指示SOC最大的车厢中电池包给所有车厢中的辅助负载供电;在接收到SOC最大的车厢的BMS发送的辅助上电成功信号时,控制所有车厢中的辅助负载进行工作。本发明的控制方法,通过SOC最大的电池包向所有车厢中的辅助负载进行供电,以达到快速消耗SOC最大的电池包的电量,实现整车电池包的电量均衡。
