The invention discloses a switching charging device for an electric vehicle. The switching charging device is characterized in that optimization design is carried out by analyzing a charging system framework, the whole vehicle is only provided with one direct current charging interface, rapid charging can be carried out by using a direct current pile, and charging can be carried out by using a slow charging pile through the switching charging device in an occasion without a rapid charging pile. The switching charging device is advantaged in that only the direct-current charging interface needsto be configured for the electric vehicle, configurations such as a vehicle-mounted charger, an alternating-current charging interface and a high-voltage wire harness are reduced, cost can be effectively reduced, the switching charging device can be adopted to realize charging in an occasion with only an alternating-current charging pile, the device can be shared by different vehicles, and operation cost is further reduced.

    本发明公开了一种电动汽车用转接充电装置,本发明通过分析充电系统架构,进行优化设计,整车只用配备一个直流充电接口,能够使用直流桩进行快充,对于没有快充桩的场合,可以通过该转接充电装置使用慢充桩进行充电。本发明对于电动汽车仅需要配置直流充电接口,减少了车载充电机、交流充电接口以及高压线束等配置,能够有效降低成本,对于只有交流充电桩的场合,可以采用该转接充电装置,实现充电,该装置在不同车辆之间可以共用,进一步降低运营成本。
