The invention relates to a vehicle-mounted charger, a control method thereof and a computer readable storage medium. The vehicle-mounted charger comprises a direct current interface used for connecting an external direct current power supply; a first switch, one end of the first switch is connected with the direct current interface, and the other end is connected with the isolation transformation module; one end of the isolation transformation module is connected with the first switch, and the other end of the isolation transformation module is connected with a high-voltage battery of the vehicle; a second switch, one end of the second switch is connected with the direct current interface, and the other end is connected with the high-voltage battery; and a processor which is in communication connection with the first switch and the second switch, and is configured to obtain charging voltage information of a corresponding direct-current power supply and current voltage information of the high-voltage battery in response to the fact that a direct-current connector is connected to the direct-current interface; and when the charging voltage of the direct-current power supply is smaller than the current voltage of the high-voltage battery, the first switch is switch on, and the isolation transformation module is controlled to boost the charging voltage so as to charge the high-voltage battery.

    本发明涉及一种车载充电机及其控制方法,以及一种计算机可读存储介质。该车载充电机包括:直流接口,用于连接外部的直流电源;第一开关,一端连接所述直流接口,另一端连接隔离变压模块;所述隔离变压模块,一端连接所述第一开关,另一端连接车辆的高压电池;第二开关,一端连接所述直流接口,另一端连接所述高压电池;以及处理器,通信连接所述第一开关和所述第二开关,并配置为:响应于直流接头接入所述直流接口,获取对应的直流电源的充电电压信息及所述高压电池的当前电压信息;以及响应于所述直流电源的充电电压小于所述高压电池的当前电压,闭合所述第一开关,并控制所述隔离变压模块对所述充电电压进行升压以向所述高压电池充电。
