The invention provides precharging for direct current fast charging. A vehicle includes a traction battery; a bus; a main contactor between the traction battery and bus; a precharge contactor betweenthe traction battery and bus in parallel with the main contactor; and a controller configured to, responsive to a first precharge mode signal, command a charging station to increase a voltage on the bus and subsequently close the precharge contactor before closing the main contactor, and responsive to a second precharge mode signal, close the precharge contactor without first commanding the charging station to increase the voltage on the bus before closing the main contactor.

    本公开提供“用于直流快速充电的预充电”。一种车辆包括牵引电池;总线;在所述牵引电池和总线之间的主接触器;与所述主接触器并联的在所述牵引电池和总线之间的预充电接触器;以及控制器,所述控制器被配置为响应于第一预充电模式信号,在闭合所述主接触器之前命令充电站增加在所述总线上的电压并且随后闭合所述预充电接触器,以及响应于第二预充电模式信号,在闭合所述主接触器之前闭合所述预充电接触器,而无需首先命令所述充电站增加在所述总线上的所述电压。
