摘　　要：随着绿色出行的提出,电动汽车代替燃油汽车的趋势越来越明显。随着大规模的电动汽车应用,甚至能够在电网用电高峰时充当储能设备对电网进行补偿。针对电动汽车的电池充放电问题,以单相双向变换器为电动汽车充电设备的主拓扑,同时提出了一种电流闭环结合中点电压闭环的控制方法实现能量双向流动。实验结果验证了所提电动汽车充放电方案的有效性,为加快电动汽车的普及提供了一定的基础。With the proposing of green transportation,the trend of electric vehicles replacing fuel vehicles is becoming increasingly evident.With the realization of large-scale application,electric vehicles can even act as energy storage devices to compensate for the power grid during peak electricity consumption.In response to the issue of battery charging and discharging in electric vehicles,a single-phase bidirectional converter is taken as the main topology of the charging equipment for electric vehicles,and a control method that combines current closed-loop and midpoint voltage closed-loop is proposed to achieve bidirectional energy flow.The experimental results verify the effectiveness of the charging and discharging scheme for electric vehicles proposed,providing a certain foundation for accelerating the popularization of electric vehicles.
