The invention discloses a vehicle power management system and a power management method thereof, and the power management method comprises the steps: when a microcontroller receives a switch closing signal, the microcontroller judges whether the voltage of the switch closing signal is lower than a voltage threshold; when the voltage of the switch closing signal is lower than the voltage threshold, stopping using the vehicle-mounted power supply to supply power to the standby battery and using the vehicle-mounted power supply to supply power to the rear-end load; starting a counter of the microcontroller; when the counting time of the counter reaches a first time threshold, stopping using the vehicle-mounted power supply to supply power to the rear-end load and using the standby battery to supply power to the rear-end load; when the counting time reaches a second time threshold, the microcontroller transmits an electric switch closing signal to a rear-end load; and when the counting time reaches a third time threshold, stopping using the standby battery to supply power to the rear-end load.

    本发明公开一种车辆电力管理系统及其电力管理方法,而电力管理方法包括:当微控制器接收到电门关闭信号时,由微控制器判断电门关闭信号的电压是否低于电压门槛。当电门关闭信号的电压低于电压门槛时,停止使用车载电源对备用电池供电且使用车载电源对后端负载供电;启动微控制器的计数器;当计数器的计数时间达到第一时间门槛时,停止使用车载电源对后端负载供电且改为使用备用电池对后端负载供电;当计数时间达到第二时间门槛时,微控制器传送电门关闭信号至后端负载;当计数时间达到第三时间门槛时,停止使用备用电池对后端负载供电。
