The invention provides an electric vehicle charging coupling device and an electric vehicle. The electric vehicle charging coupling device comprises a vehicle connecting port, a vehicle-mounted power switch, a vehicle-mounted charger and a vehicle control device. The vehicle connecting port is connected with the charging gun; the vehicle control device obtains the power output type of the charging gun through the vehicle connection port, and when it is determined that the power output type of the charging gun is direct current, the vehicle-mounted charger is controlled not to work, and the vehicle-mounted power switch is controlled to conduct a path between the vehicle connection port and the power battery so as to charge the power battery; when it is determined that the power output type of the charging gun is alternating current, the vehicle-mounted power switch is controlled to disconnect a path between the vehicle connecting port and the power battery, the vehicle-mounted charger is controlled to work, and the input alternating current power supply is output to the power battery after being subjected to direct current voltage conversion. According to the invention, the AC charging path and the DC charging path are coupled together, so that the electric vehicle with the single charging interface has the functions of fast charging and slow charging at the same time.

    本发明提出一种电动汽车充电耦合装置和电动汽车,电动汽车充电耦合装置包括车辆连接口、车载电源开关、车载充电机和车辆控制装置。车辆连接口与充电枪连接;车辆控制装置通过车辆连接口获取充电枪的电源输出类型,在确定充电枪的电源输出类型为直流时,控制车载充电机不工作,控制车载电源开关导通车辆连接口与动力电池之间的通路,以给动力电池进行充电;在确定充电枪的电源输出类型为交流时,控制车载电源开关断开车辆连接口与动力电池之间的通路,并控制车载充电机工作,对输入的交流电源进行直流电压转换后输出至动力电池。本发明通过将交流充电通路与直流充电通路耦合在一起,使得单充电接口的电动汽车同时具备快充和慢充的功能。
