The embodiment of the invention relates to a charging circuit, an electric vehicle and a charging method. The charging circuit is applied to the electric automobile, the electric automobile comprises a power supply and a motor, and the motor comprises a charging and discharging circuit. The charging circuit comprises a control circuit and a switching circuit. The control circuit is used for controlling the switching circuit to disconnect the access between the power supply and the charging pile and controlling the switching circuit to conduct the access between the charging and discharging circuit and the charging pile, so that the charging pile charges the charging and discharging circuit; and when the discharging condition is met, the switch circuit is controlled to conduct the access between the power supply and the charging pile and to disconnect the access between the charging and discharging circuit and the charging pile, so that the charging and discharging circuit discharges and the charging pile charges the power supply at the same time. According to the charging circuit, the voltage of the charging pile can be boosted to charge the power supply of the electric automobile only through the control circuit and the switching circuit, and the internal space of the electric automobile is not occupied while the high-voltage power supply is charged through the low-voltage charging pile.

    本公开实施例涉及一种充电电路、电动汽车和充电方法。所述充电电路应用于电动汽车,电动汽车包括电源和电机,电机包括充放电电路;充电电路包括:控制电路和开关电路;控制电路,用于控制开关电路断开电源与充电桩之间的通路,以及控制开关电路导通充放电电路与充电桩之间的通路,以使充电桩为充放电电路充电;并在满足放电条件时控制开关电路导通电源与充电桩之间的通路导通,以及控制开关电路断开充放电电路与充电桩之间的通路,以使充放电电路放电和充电桩同时为电源充电。该充电电路仅通过控制电路和开关电路就能实现将充电桩的电压升高为电动汽车的电源充电,在通过低压充电桩给高压电源充电的同时不会占用电动汽车内部空间。
