The invention discloses a vehicle battery replacement control method and system and a vehicle, the vehicle comprises a vehicle control unit, a first compartment and a second compartment, and the method comprises the steps that the vehicle control unit obtains a battery replacement instruction; the vehicle control unit responds to the battery replacement instruction and sends a closing instruction to the battery managers of the first compartment and the second compartment; and the battery managers of the first carriage and the second carriage close the extended power supply circuit contactor in the carriage. According to the embodiment of the invention, when the vehicle is in the high-voltage power-on state for battery replacement operation, the expansion power supply circuit configured in each compartment of the vehicle ensures that the power battery pack in the compartment serves as a power supply to supply power to the load of the compartment to be subjected to battery replacement in the battery replacement process; therefore, after the electric connection between the vehicle power battery pack and the high-voltage circuit is cut off, the normal power supply of the load in the to-be-replaced compartment is still maintained, the normal operation of the whole vehicle load in the battery replacement process is realized, and the user experience is improved.

    本申请公开了一种车辆换电控制方法、系统及车辆,该车辆包括整车控制器、第一车厢及第二车厢,该方法包括:整车控制器获取换电指令;整车控制器响应换电指令,向第一车厢及第二车厢的电池管理器发送闭合指令;第一车厢及第二车厢的电池管理器闭合本节车厢中扩展供电电路接触器。本申请实施例在车辆处于高压上电状态下换电操作时,通过配置在车辆中每个车厢内的扩展供电电路,确保换电过程中,其中的车厢中的动力电池包作为供电电源,向待换电车厢的负载供电,使得待换电车厢在切断车辆动力电池包与高压电路之间的电连接后,仍然维持换电车厢内负载的正常供电,实现了换电过程中整车负载的正常运行,提升了用户体验。
