The invention provides a fuel cell direct-current converter, an electric vehicle power supply system and a control method. The fuel cell direct-current converter is arranged between a fuel cell and adriving motor; the fuel cell can supply power to the driving motor through the fuel cell direct-current converter; the fuel cell direct-current converter comprises a charging input interface and a charging output interface, the charging input interface is connected with an external charging power supply, the charging output interface is connected with a power battery, and when the fuel cell does not supply power to the driving motor, the external charging power supply can charge the power battery through the fuel cell direct-current converter. The external charging interface is integrated on the fuel cell direct-current converter, so that the fuel cell direct-current converter can replace a vehicle-mounted charger, the use benefit of the fuel cell direct-current converter can be improved,and an automobile power system is more compact in structure; and meanwhile, a photovoltaic array can be directly connected for charging, so that the system is more environment-friendly and higher in energy utilization rate.

    本发明提供一种燃料电池直流变换器、电动车供电系统及控制方法,所述燃料电池直流变换器设置在燃料电池和驱动电机之间,所述燃料电池可以通过所述燃料电池直流变换器向所述驱动电机供电,包括充电输入接口和充电输出接口,所述充电输入接口与外接充电电源连接,所述充电输出接口和动力电池连接,当所述燃料电池不向所述驱动电机供电时,所述外接充电电源可以通过所述燃料电池直流变换器向动力电池充电。本发明通过在燃料电池直流变换器上集成外接充电接口,使其可以替代车载充电器,能提高燃料电池直流变换器使用效益,使汽车动力系统结构更加紧凑;同时可直接接入光伏阵列进行充电,更加环保,能量利用率更高。
