The invention discloses an extended-range vehicle-to-vehicle charging system and method, a discharging vehicle and a charging vehicle, and belongs to the technical field of vehicle charging. A vehicle-to-vehicle charging wire harness in the system is used for connecting a first direct-current charging socket and a second direct-current charging socket; a main negative contactor in the system is used for disconnecting a rechargeable energy storage module from a charging vehicle; a generator controller in the system is connected with a range extender through a high-voltage three-phase wire harness and used for converting three-phase alternating current output by the range extender into direct current; a fast charging contactor in the system is used for transmitting charging current output by a range extender to a second direct current charging socket through a vehicle-to-vehicle charging wire harness connected with a first direct current charging socket. By adopting the system, direct-current charging can be directly carried out on the vehicle through the range extender, and the charging efficiency is improved.

    本发明公开了一种车辆充电技术领域的增程式车对车充电系统和方法、放电车辆以及充电车辆,所述系统中的车对车充电线束用于连接第一直流充电插座和第二直流充电插座;所述系统中的主负接触器用于断开可充电储能模块与充电车辆的连接;所述系统中的发电机控制器通过高压三项线束与增程器连接,用于将所述增程器输出的三相交流电转换为直流电;所述系统中的快充接触器用于将增程器输出的充电电流经连接第一直流充电插座的车对车充电线束输送至第二直流充电插座。采用该系统能够通过增程器直接对车辆进行直流充电,提高充电效率。
