The invention provides a ground charging system for a power battery of a dual-power-source electric locomotive, and the system comprises an existing ground power supply which charges the power battery of the locomotive, and the existing ground power supply comprises an AC power supply and a DC power supply; when the alternating current power supply is used for charging, the alternating current power supply is connected with the output side of an auxiliary inverter of the locomotive to reversely rectify the alternating current into direct current, and the direct current is subjected to voltage reduction through the power battery and a DC-DC device of a locomotive middle bus to charge the power battery; when the direct-current power supply is used for charging, the direct-current power supply is connected with the input side of a converter rectifier of the locomotive, and after being boosted by the boosted circuit, the direct-current power supply charges the power battery through the DC-DC device. The power battery is charged by utilizing the equipment of the electric locomotive and the existing ground power supply of a user, additional charging equipment does not need to be added on the electric locomotive, the user does not need to additionally configure a ground charging power supply, and the cost is saved.

    本公开提供了一种双动力源电力机车动力电池地面充电系统,包括:既有地面电源,通过既有地面电源为机车的动力电池充电,既有地面电源包括交流电源和直流电源;当采用交流电源充电时,交流电源与机车的辅助逆变器输出侧连接以将交流电反向整流为直流电,再通过动力电池与机车中间母线的DC‑DC装置将直流电降压后为动力电池充电;当采用直流电源充电时,直流电源与机车的变流器整流器的输入侧连接,并经过升压电路升压后,再通过DC‑DC装置为动力电池充电。本发明利用电力机车本身自带设备以及用户既有地面电源实现了为动力电池充电,电力机车上无需增加额外的充电设备,用户也不需额外配置地面充电电源,节约了成本。
