The invention provides a charging and discharging battery replacing method and device for an electric vehicle, and the method comprises the specific steps: an AC/DC controller monitors the change of charging demands in real time, and provides a time sequence according to the charging demands of a battery box and a charging pile of the electric vehicle; when the charging pile and the battery box need to be charged at the same time, the AC/DC controller compares the capacity sum S of the charging requirements of the charging pile and the battery box with the charging capacity S0 of the AC/DC charging and discharging unit, and corresponding operation is completed; when the charging pile and the battery box do not need to be charged at the same time, the AC/DC controller compares the capacity sum S of the charging requirements of the charging pile and the battery box with the charging capacity S0 of the AC/DC charging and discharging unit, and corresponding operation is completed; and according to the voltage and current of the battery fed back by the charging pile battery management system and the electric vehicle battery box management system in real time, the output voltage and current of the charging pile are adjusted, and charging is completed. Charging and battery swapping can be provided for the electric vehicle, electric energy is provided for the power grid according to power grid dispatching, and the utilization rate and economic benefits of the charging and battery swapping station are effectively improved.

    本发明提供一种用于电动汽车的充放换电方法及其换电装置,具体步骤为:AC/DC控制器实时监控充电需求变化,并根据电动车电池箱和充电桩的充电需求提供时序;当充电桩和电池箱同时需求充电时,AC/DC控制器比较充电桩和电池箱的充电需求的容量总和S与AC/DC充放电单元的充电容量S0,完成对应操作;当充电桩和电池箱不同时需求充电时,AC/DC控制器比较充电桩和电池箱的充电需求的容量总和S与AC/DC充放电单元的充电容量S0,完成对应操作;根据充电桩电池管理系统和电动车电池箱管理系统实时反馈电池的电压电流,调整充电桩的输出电压电流,并完成充电。本发明不仅能为电动车提供充换电,而且根据电网调度为电网提供电能,有效的提高充换电站的利用率和经济效益。
