The invention relates to a method for increasing the mileage of a pure electric traction vehicle. According to the method, a second power battery pack is additionally arranged on a trailer, and the pure electric traction vehicle can use electric energy in an original first power battery pack and the second power battery pack on the trailer, so that the energy expansion effect is achieved, and the driving mileage of the pure electric traction vehicle is increased or doubled; the second power battery pack on the trailer is connected with the pure-power traction vehicle through the high-voltage connector comprising the locking device, the high-voltage switch and the alarm, effective locking can be achieved in the vehicle starting and running process, the connection state can be monitored in real time, the high-voltage switch can be immediately switched off once abnormity occurs, meanwhile, the alarm is sent to a cab operator, and the safety of the cab is guaranteed. And the first power battery is switched to output electric energy to drive the vehicle, so that the vehicle can run safely and stably.
本发明涉及一种增加纯电动牵引汽车行驶里程的方法。该方法通过在挂车上增加第二动力电池组,纯电动牵引汽车可以使用自身原有的第一动力电池组和挂车上的第二动力电池组中的电能,从而达到能量扩容效果,实现纯电动牵引汽车的行驶里程增加或翻倍;通过设置包含锁紧装置、高压开关、及报警器的高压连接器将挂车上的第二动力电池组与纯动力牵引汽车连接,可在车辆启动及运行过程中有效锁紧并实时监测连接状态,一旦出现异常可立即断开高压开关,同时向驾驶室员发出报警,并切换到第一动力电池输出电能驱动车辆,保证车辆能安全、平稳地行驶。
