The invention relates to the technical field of charging piles, in particular to a charging and discharging method of a mobile charging pile. The charging and discharging method comprises the following steps. Order information of a user is acquired; acquiring the GPS positioning of the user and driving to the GPS positioning; judging whether the charging gun is connected; the VCU outputs a discharge wake-up signal; bMS discharge preparation is carried out; the BMS closes the negative relay, and the VCU sends a high-voltage instruction to the CCU; the CCU closes a pre-charging relay; judging whether pre-charging is completed or not; the BMS closes the positive discharge relay; the VCU sends a charging starting instruction to the CCU; the CCU disconnects the pre-charger; the VCU sends a charging gun locking signal to the CCU; judging whether the electronic lock is locked or not; the CCU controls to close the relay K1 and the relay K2; the DC-DC works; charging is started; therefore, the charging requirement of the vehicle can be well met.
本发明涉及充电桩技术领域,具体地说,涉及一种移动式充电桩的充放电方法。该充放电方法包括如下步骤;获取用户的订单信息;获取用户的GPS定位并行驶至所述GPS定位;判断充电枪是否连接;VCU输出放电唤醒信号;BMS放电准备;BMS闭合负继电器,VCU发送上高压指令给CCU;CCU闭合预充继电器;判断预充是否完成;BMS闭合放正继电器;VCU发送启动充电指令给CCU;CCU断开预充电器;VCU发送充电枪上锁信号给CCU;判断电子锁是否上锁;CCU控制闭合K1继电器、K2继电器;DC‑DC工作;开始充电;通过上述,故而较佳地满足车辆充电的需求。
