The invention discloses a high-power electric vehicle power supply system based on a direct-current touch net and a coordination control method. The system comprises a ground end power supply system and a vehicle end power supply system. When the trolley pole or the pantograph is in contact with the sliding contact line to take electricity, the switching circuit is switched off, the sliding contact line supplies power to the driving motor through the motor controller, and the sliding contact line charges the power battery through the vehicle-mounted charger; and when the trolley pole or the pantograph is separated from the sliding contact line and the voltage of the input end of the motor controller is reduced below the voltage of the power battery, the switching circuit is automatically switched on, and the power battery supplies power to the motor controller.

    本发明公开了基于直流触网的大功率电动汽车供电系统及协调控制方法,系统包括地面端供电系统和车端供电系统。当集电杆或受电弓接触到滑触线取电后,切换电路断开,滑触线通过电机控制器给驱动电机供电,且滑触线通过车载充电机给动力电池充电;当集电杆或受电弓脱开滑触线且电机控制器输入端电压下降到动力电池电压以下时,切换电路自动接通,动力电池给电机控制器供电。
