The invention relates to a vehicle voltage conversion system and method, a vehicle voltage conversion controller and a control method thereof, a computer readable storage medium, electronic equipment and a vehicle. The vehicle voltage conversion system comprises a three-phase motor, a motor driving control circuit, a charging port and a vehicle voltage conversion controller. The motor drive control circuit is connected between a power battery and a three-phase motor of the vehicle and comprises three switch bridge arms which are connected in parallel. The charging port comprises a first output end and a second output end, the first output end is connected to the midpoints of the switch bridge arms corresponding to the windings through the windings of the three-phase motor, and the second output end is connected to one pole of the power battery. And the vehicle voltage conversion controller is configured to select a two-phase winding which generates a larger inductance value in the windings of the three-phase motor by controlling the connection and disconnection of the three switch bridge arms according to the rotor position angle of the three-phase motor so as to carry out voltage conversion between the charging port and the power battery.

    本申请涉及车辆电压变换系统及其方法、车辆电压变换控制器及其控制方法、计算机可读存储介质和电子设备及车辆。本申请的车辆电压变换系统包括三相电机、电机驱动控制电路、充电口和车辆电压变换控制器。电机驱动控制电路连接在车辆的动力电池和三相电机之间,并包括三个相互并联的开关桥臂。充电口包括第一输出端和第二输出端,第一输出端经由三相电机的每个绕组而分别连接到与各个绕组对应的开关桥臂的中点,第二输出端连接到动力电池的一极。车辆电压变换控制器配置成根据三相电机的转子位置角,通过控制三个开关桥臂的导通和断开,而选择三相电机的绕组中产生电感值更大的两相绕组,以在充电口和动力电池之间进行电压变换。
