The invention provides a V2V direct current charging system for a plug-in hybrid electric vehicle. The V2V direct current charging system comprises a charging connecting device, a discharging vehicle and a charging vehicle, firstly, after a charging connection device completes connection of a discharging vehicle and a charging vehicle, the discharging vehicle is awakened firstly, and high-voltage power-on of the discharging vehicle is completed; the discharging vehicle sends the maximum output capacity of the discharging vehicle and a discharging ready signal to the charging connection device through CAN communication; the charging connection device wakes up the charging vehicle based on the discharging ready signal to enable the charging vehicle to complete high-voltage power-on; the charging connection device simulates the charging pile to perform charging handshake and charging parameter configuration with the charging vehicle according to a preset standard; after the charging vehicle is ready, the discharging vehicle provides power through the engine to drive the generator to generate electricity so as to charge the power battery of the charging vehicle.

    本发明提供了一种插电式混合动力汽车V2V直流充电系统,包括:充电连接装置,放电车辆及充电车辆;首先,充电连接装置完成放电车辆和充电车辆的连接后,先唤醒放电车辆,使放电车辆完成高压上电;放电车辆通过CAN通信将其自身的最大输出能力和放电准备就绪信号发送给充电连接装置;充电连接装置基于放电准备就绪信号唤醒充电车辆,使充电车辆完成高压上电;充电连接装置再模拟充电桩按照预设标准与充电车辆进行充电握手、充电参数配置;在充电车辆准备就绪后,放电车辆通过发动机提供动力驱动发电机发电来为充电车辆的动力电池充电。
