The invention discloses a charging and discharging control method and system for a pure electric tractor and the tractor. The system comprises a whole vehicle controller, a battery management system, a power battery pack, a PTO driving motor controller, a PTO driving motor and a power distribution box. When the vehicle is parked and only the PTO driving motor outputs power, the power distribution box is connected with the charging pile, and when the vehicle control unit receives a charging work instruction, a PTO driving motor contactor connected between the power distribution box and a PTO driving motor controller is controlled to be closed; the charging pile provides output power for the PTO driving motor through the power distribution box and supplements electric quantity for the power battery pack at the same time. When the vehicle is parked and only the PTO driving motor outputs power, the charging pile is connected into the whole vehicle, the PTO driving motor is supplied with energy by using the electric energy of the charging pile, and meanwhile, the power battery is supplemented with electric quantity, so that the electric quantity of the battery can be kept in a high state in the next use working condition, and the endurance time is prolonged.
本发明公开一种纯电动拖拉机充放电控制方法、系统及拖拉机,系统包括:整车控制器、电池管理系统、动力电池包、PTO驱动电机控制器、PTO驱动电机和配电盒;车辆驻车且只有PTO驱动电机输出功率时,通过配电盒连接充电桩,整车控制器接收到充电工作指令时,控制连接于配电盒与PTO驱动电机控制器之间的PTO驱动电机接触器闭合;充电桩通过配电盒为PTO驱动电机提供输出功率,同时为动力电池包补充电量。本发明在车辆驻车且只有PTO驱动电机输出功率时,将充电桩接入整车,通过使用充电桩的电能来给PTO驱动电机供能,同时为动力电池补充电量,这样就可以在下一个使用工况中,电池电量保持较高的状态,增加了续航时间。
