中文摘要：
为了实现通用型电动汽车充电机对电动汽车的快速充电,研究了电动汽车各种充电方法以及蓄电池SOC检测方法,给出了充电拓扑图.通过采样电动汽车蓄电池端电压、电流以及温度等判断充电模式,结合采用恒流、带放电脉冲和低恒压充电3种方式对蓄电池进行充电.仿真结果验证了快速充电的合理性.
英文摘要：
In order to achieve fast charging of general electric vehicle charging piles for electricvehicles, the charging topology of the battery is given after studying a variety of charging methodsof battery and detection methods of SOC. The charging mode is determined by sampling theterminal voltage, current, and temperature of the battery. The battery is charged through acombitlation of the three following methods： constant current charging, low constant voltagecharging and charging with discharge pulse. By simulating, fast charging is justified.
