The invention discloses a train and an emergency power supply control method and system thereof. The method comprises the steps that battery real-time allowable discharging states sent by BMS of all carriages are obtained; when it is determined that any compartment does not allow battery discharging according to the real-time battery discharging allowing states sent by the BMS of all the compartments, the compartment is controlled to be subjected to high-voltage discharging; after it is determined that the carriage completes high-voltage electricity withdrawing, the carriage adjacent to the carriage is controlled to conduct auxiliary electricity withdrawing; after it is determined that the carriage adjacent to the carriage completes auxiliary power-off, the auxiliary load of the carriage is controlled, the auxiliary load of the carriage adjacent to the carriage is connected into a through loop, and an auxiliary power-on instruction is sent to the BMS of the carriage adjacent to the carriage; therefore, the battery pack of the carriage adjacent to the carriage supplies power to the carriage and the auxiliary load of the carriage in emergency. Therefore, when the faulty compartment is in a discharge disallowed state, the adjacent compartment can supply power to the auxiliary load of the faulty compartment emergently so as to ensure normal operation of the auxiliary function of the compartment.

    本发明公开了一种列车及其紧急供电控制方法和控制系统,所述方法包括:获取所有车厢的BMS发送的电池实时允许放电状态;根据所有车厢的BMS发送的电池实时允许放电状态确定任意一节车厢不允许电池放电时,控制该节车厢高压退电;确定该节车厢完成高压退电后控制与该节车厢相邻车厢进行辅助退电;确定与该节车厢相邻车厢完成辅助退电后,控制该节车厢的辅助负载、与该节车厢相邻车厢的辅助负载接入贯通回路,并向与该节车厢相邻车厢的BMS发送辅助上电指令,以便与该节车厢相邻车厢的电池包给自身车厢和该节车厢的辅助负载紧急供电。从而能够在故障车厢出现放电不允许状态时,通过相邻车厢为故障车厢的辅助负载紧急供电,以保证车厢辅助功能正常工作。
