The invention discloses a method, a device, equipment and a storage medium for battery replacement circulation protection of an electric locomotive, and the method comprises the steps that a three-stage BMS monitors the electric quantity of a locomotive battery and the electric quantity of a battery of a battery car in real time, and judges whether a battery replacement circulation protection function needs to be started or not according to the electric quantity of the locomotive battery and the electric quantity of the battery of the battery car; when the three-stage BMS judges that the current conversion circulating current protection function needs to be started, the current conversion circulating current protection function is started, and meanwhile the connection state of an interlocking wire connector and the connection state of a high-voltage connector are monitored in a polling mode; and the three-stage BMS performs battery replacement circulation protection processing on the electric motor car by using the connection state of the interlocking wire connector and the connection state of the high-voltage connector.

    本发明公开一种电动机车换电环流保护的方法、装置、设备及存储介质,其方法包括:三级BMS实时监测机车电池的电量和电池车电池的电量,并根据所述机车电池的电量和所述电池车电池的电量,判断是否需要启动换电环流保护功能;当所述三级BMS判断需要启动换电环流保护功能时,启动所述换电环流保护功能,同时轮询监测互锁线连接器的连接状态和高压连接器的连接状态;所述三级BMS利用所述互锁线连接器的连接状态和所述高压连接器连接状态,对所述电动机车进行换电环流保护处理。
