The invention discloses a vehicle-mounted power supply system of an electric vehicle and a control method of the vehicle-mounted power supply system. The vehicle-mounted power supply system of the electric vehicle comprises a power supply system control unit, a vehicle-mounted energy storage system, a bidirectional vehicle-mounted charger, a power distribution device and a power supply socket, the vehicle-mounted energy storage system is electrically connected with the two-way vehicle-mounted charger, and the vehicle-mounted energy storage system is used for providing electric energy required by driving and electric components for the vehicle; the bidirectional vehicle-mounted charger is a vehicle-mounted charger with an inversion function and supports a high-voltage direct current and alternating current 220V bidirectional charging/inversion function; the power distribution device is connected with the bidirectional vehicle-mounted charger through an alternating current circuit, and a discharge switch is arranged on the power supply socket; the power supply system control unit communicates with the power distribution device, the bidirectional vehicle-mounted charger, the vehicle-mounted energy storage system, the motor control unit and the high-voltage accessory module through CAN communication. The technical problems that in the prior art, the vehicle-mounted power supply power is small, and discharging to loads and equipment in a vehicle cannot be met in the driving process can be solved.

    本发明公开了一种电动汽车车载供电系统及其控制方法,该电动汽车车载供电系统包括供电系统控制单元、车载储能系统、双向车载充电机、配电装置和供电插座;车载储能系统与所述双向车载充电机电性连接,车载储能系统用于为车辆提供驱动和用电部件所需的电能;双向车载充电机为带有逆变功能的车载充电机,支持高压直流与交流220V双向充电/逆变功能;配电装置与双向车载充电机通过交流电路连接,供电插座上设有放电开关;供电系统控制单元通过CAN通讯分别与配电装置、双向车载充电机、车载储能系统、电机控制单元和高压附件模块通讯。本发明能够解决现有技术车载供电功率较小,不能满足行驶过程中对车内负载和设备放电的技术问题。
