The invention provides a mutual charging system between pure electric vehicles and a control method thereof, the system comprises a first vehicle, a first converter is arranged in the first vehicle, one end of the first converter is connected with a first battery, and the other end of the first converter is connected with a first high-voltage input/output end; a second converter is arranged in the second vehicle, one end of the second converter is connected with a second battery, and the other end of the second converter is connected with a second high-voltage input/output end; the other end of the first converter is connected with the other end of the second converter; external floating voltage is boosted or reduced to voltage required by a battery of a rescued vehicle through a converter, two output control relays are added at the same time, and when the battery of a discharging vehicle needs to be discharged, the two relays are closed, and the battery can serve as a power source to carry out charging output on a to-be-charged vehicle. Therefore, the problem that the working vehicle is difficult to charge when no power exists in the external environment is solved.
本发明提供一种纯电车辆间相互补电系统及其控制方法,包括第一车辆,第一车辆内部设置有第一变换器,第一变换器的一端连接第一电池,第一变换器的另一端连接有第一高压输入/输出端;第二车辆,第二车辆内部设置有第二变换器,第二变换器的一端连接第二电池,第二变换器的另一端连接有第二高压输入/输出端;第一变换器的另一端与第二变换器的另一端连接;通过变换器将外部浮动的电压升高或降低至被救援车辆电池所需电压,同时加入两个输出控制继电器,当放电车辆所带电池需要放电时,闭合两个继电器就可将电池作为电源向待充电车辆进行充电输出,从而降低作业车辆在外部环境无电时存在的充电困难的问题。
