The invention discloses a charging and discharging control system and method for an electric automobile and the electric automobile. The charging and discharging control system comprises a first switch unit and a second switch unit which are arranged between a first charging and discharging interface and a power battery in series; one end of the vehicle-mounted bidirectional AC charger is electrically connected with the second charging and discharging interface through a third switch unit, and the other end of the vehicle-mounted bidirectional AC charger is electrically connected with the power battery through a second switch unit; a fourth switch unit is arranged between the first charging and discharging interface and the second charging and discharging interface; the control unit is used for obtaining a charging and discharging mode and controlling the first switch unit, the second switch unit, the third switch unit and the fourth switch unit to be connected or disconnected according to the charging and discharging mode so that the electric vehicle can be charged or discharged in different charging and discharging modes. According to the technical scheme, the charging or discharging requirement in any mode is met, and the charging and discharging intellectualization and diversification of the electric vehicle are improved.

    本发明公开了一种电动汽车的充放电控制系统及控制方法、电动汽车,包括:第一开关单元和第二开关单元串联设置在第一充放电接口和动力电池之间;车载双向交流充电机的一端通过第三开关单元与第二充放电接口电连接,车载双向交流充电机的另一端通过第二开关单元与动力电池电连接;第一充放电接口与第二充放电接口之间设置有第四开关单元;控制单元用于获取充放电模式,并根据充放电模式控制第一开关单元、第二开关单元、第三开关单元和第四开关单元的导通或断开,以使电动汽车进行不同充放电模式的充电或放电。以上技术方案,满足任意模式下的充电或放电需求,提升电动汽车的充、放电智能化和多样化。
