The invention discloses an electric vehicle and a photovoltaic charging system thereof, and the photovoltaic charging system comprises a first charging port which is suitable for being connected with a photovoltaic power generation device; the motor driver is connected with the motor and is used for driving the motor to operate according to the electric power provided by the power battery; the control unit is used for configuring the connection relation between the first charging port and the motor driver and the motor when it is detected that the first charging port is connected with the photovoltaic power generation device, so that the motor driver and the motor form a conversion circuit, and the conversion circuit is controlled to convert the direct current output by the photovoltaic power generation device so as to charge the power battery. The photovoltaic power generation device inputs direct current to the power battery through a conversion circuit composed of the motor driver and the motor, the power battery is charged through an internal circuit of the electric vehicle and the photovoltaic power generation device, and therefore the problem that outdoor charging is difficult is solved.

    本发明公开了一种电动车辆及其光伏充电系统,其中,光伏充电系统包括:第一充电口,适于连接光伏发电装置;电机驱动器和电机,电机驱动器与电机相连,且用于根据动力电池提供的电力驱动电机运行;控制单元,用于在检测到第一充电口连接光伏发电装置时,配置第一充电口与电机驱动器和电机的连接关系,以使电机驱动器和电机组成变换电路,并控制变换电路对光伏发电装置输出的直流电进行变换,以给动力电池充电。光伏发电装置通过电机驱动器和电机组成的变换电路向动力电池输入直流电,实现了利用电动车辆的内部电路和光伏发电装置对动力电池充电,从而解决了户外充电困难的问题。
