The invention provides a vehicle-mounted power supply system, a control method and a vehicle, and relates to the technical field of vehicle-mounted power supply control, and the vehicle-mounted power supply system comprises an input on-off switch, and at least one of a positive high-voltage path and a negative high-voltage path arranged at the high-voltage side of a vehicle-mounted power supply module; the input on-off control circuit is arranged between the input on-off switch and the vehicle-mounted battery management system, takes electricity from the high-voltage side, and receives an input cut-off control signal generated by the micro-control unit and a locking/awakening signal generated by the vehicle-mounted battery management system when the high-voltage side and the vehicle-mounted power supply module are in a cut-off state; and the control module is used for controlling the input on-off switch to switch the off state and the on state between the high-voltage side and the vehicle-mounted power supply module, and setting a locking/awakening signal of the input on-off switch to be a preset state according to the input cut-off control signal. According to the vehicle-mounted power supply system provided by the invention, the standby loss of the vehicle-mounted power supply module can be greatly reduced.

    本申请提供了一种车载供电系统、控制方法及车辆,涉及车载电源控制技术领域,车载供电系统包括:输入通断开关,设置在车载电源模块的高压侧的正高压路径以及负高压路径中的至少之一;输入通断控制电路,设置在输入通断开关与车载电池管理系统之间,且在高压侧取电,当高压侧与车载电源模块之间为断开状态时,接收由微控制单元产生的输入切断控制信号以及由车载电池管理系统产生的锁死/唤醒信号,以控制输入通断开关切换高压侧与车载电源模块之间的断开状态及连通状态,且根据输入切断控制信号设置输入通断开关的锁死/唤醒信号为预设状态。本申请所提供的车载供电系统可以大大降低车载电源模块的待机损耗。
