The invention discloses a charging and discharging control system, a control method thereof and an electric vehicle, and the charging and discharging control system comprises a DC/DC conversion unit, a motor control unit and a generator control unit which are connected with one another, and an isolation conversion unit, a first controllable switch unit, a second controllable switch unit and a fifth controllable switch unit, through cooperation of the multiple units, when the power battery unit needs to be charged and discharged, energy isolation conversion between the power battery unit and external charging and discharging equipment can be achieved. Therefore, the charging and discharging control system can save the vehicle control cost and reduce the weight and the size of the system by multiplexing the switching tubes in the units, and is beneficial to improving the driving mileage and the cruising ability of the electric vehicle.

    本发明公开了一种充放电控制系统及其控制方法、电动车辆,该充放电控制系统包括相互连接的DC/DC变换单元、电动机控制单元和发电机控制单元、以及隔离转换单元、第一可控开关单元、第二可控开关单元、第五可控开关单元,通过上述多个单元配合,从而能够在动力电池单元需要充放电时,实现动力电池单元与外部充放电设备之间的能量隔离转换。由此,该充放电控制系统通过对各单元中开关管的复用,能够节省车辆控制成本,降低系统重量和体积,有助于提高电动车辆的行驶里程和续航能力。
