The invention provides a high-voltage charging system and method for a new energy automobile. The charging voltage of the current charging pile is obtained through the communication detection unit, the driving signal is correspondingly output through the switch driving unit, and the driving signal is utilized to control each switch element in the JFET switch array. The serial and parallel connection states of the connection lines among the battery packs in the battery pack array are correspondingly switched through the on-off states of the switch elements, so that the battery packs are connected into a plurality of charging pack groups matched with the charging voltage of the current charging pile, and the charging pack groups are charged. As the number of the battery packs in each charging pack group can be dynamically adjusted, the charging pile can be matched with a high-voltage charging pile to realize high-voltage charging, and can also be matched with charging piles with other charging voltages, so that the charging efficiency and the safety are ensured.
本申请提供一种用于新能源汽车的高压充电系统及方法。本申请中通过通讯检测单元获得当前充电桩的充电电压而相应的通过开关驱动单元输出驱动信号,利用驱动信号控制JFET开关阵列中各开关元件,通过各开关元件的通断状态而相应切换电池组阵列中各组电池包之间连接线路的串、并联状态,将各组电池包连接为匹配于当前充电桩充电电压的若干充电包组,对各充电包组进行充电。由于本发明可以动态地通过调节各充电包组中电池包的数量,因而可以匹配于高压充电桩实现高压充电,也可匹配于其他充电电压的充电桩,保证充电效率和安全性。
