The embodiment of the invention provides a vehicle-mounted power supply management system, a management method and a new energy vehicle. According to the vehicle-mounted power supply management system, the direct current of the first voltage is converted into the direct current of the second voltage, the current potential of the battery pack is monitored in real time, and when the current potential of the battery pack is lower than or equal to the first voltage, the battery pack is directly charged with the first voltage through the first charging circuit; and when the current potential of the battery pack is greater than the first voltage, the second charging circuit charges the battery pack by using the boosted second voltage, so that the charging pile of which the highest charging voltage is lower than the highest voltage of the battery pack can also meet the charging requirement of the high-voltage battery pack, the investment of charging pile reconstruction can be saved, and the charging efficiency is improved. And charging choices for charging the vehicle carrying the high-voltage battery pack can be increased.

    本申请实施例提供了一种车载电源管理系统、管理方法及新能源汽车。该车载电源管理系统通过将第一电压的直流电转换为第二电压的直流电,并对电池包的当前电位进行实时监测,当电池包的当前电位低于或等于第一电压时,则直接通过第一充电电路以第一电压对电池包进行充电,当电池包的当前电位大于第一电压时,则以第二充电电路利用升压后的第二电压对电池包进行充电,从而使得最高充电电压低于电池包的最高电压的充电桩也能够满足高压电池包的充电需求,既能够节省充电桩改建的投入,也能够增加搭载高压电池包的车辆充电的充电选择。
