The invention discloses a vehicle power management system, and belongs to the technical field of power management. The system comprises a power supply switching controller, a battery pack 1, a battery pack 2, a BMS1, a BMS2 and an external charging and discharging circuit, and during discharging switching control of the battery pack 1 and the battery pack 2, the BMS1 and the BMS2 are powered on at the same time, the battery pack 1 is controlled to discharge, and when the power switching controller detects that the electric quantity of the battery pack 1 is too small, the battery pack 2 is switched to start discharging, and the battery pack 1 stops discharging. And when the electric quantity of one battery is insufficient, the system is actively switched to the other battery to supply power, so that the system is reliable and convenient.

    本专利公开了一种车辆电源管理系统,属于电源管理技术领域。包含有电源切换控制器,电池组1和电池组2,BMS1和BMS2,以及外部充放电线路;电池组1和电池组2放电切换控制时:BMS1和BMS2同时上电,控制电池组1放电,当电源切换控制器检测到电池组1电量过小时,切换为电池组2开始放电,电池组1停止放电。实现两组电池自主切换,当一块电池电量不足时,系统主动切换到另一组电池供电,可靠便捷。
