The invention discloses a power management system, a management method and device thereof and a vehicle. The system comprises a main power supply loop and a standby power supply loop. The main power supply supplies power to the load through the main power supply loop, and the load comprises an external equipment unit, a vehicle machine unit and an instrument unit; the standby power loop comprises a standby power supply, a first switch and a second switch; wherein the standby power supply is connected with the external equipment unit through the first switch, and is connected in parallel with the vehicle machine unit and the instrument unit through the second switch; the vehicle machine unit is used for monitoring real-time power supply parameters of the main power supply and the standby power supply respectively, and determining current state information of the main power supply based on the real-time power supply parameters; and controlling the on-off states of the first switch and the second switch according to the current state information of the main power supply. Through the system, switching power supply between the main power supply and the standby power supply can be performed according to the real-time power supply state of the main power supply, so that the power supply stability of the power supply is improved, and normal operation of vehicle system functions is ensured.
