The invention discloses a multi-power-supply power system of a hydrogen energy automobile. A fuel cell is electrically connected with a first high-voltage distribution box through a fuel cell booster,a power cell and a super capacitor are electrically connected with the first high-voltage distribution box, and the first high-voltage distribution box is electrically connected with a load system ofan automobile. The fuel cell, the fuel cell booster, the power cell, the super capacitor, the first high-voltage distribution box and the load system are all electrically connected with the vehicle control unit. When the vehicle is started, the accelerator pedal is stepped down, at the moment, the power battery and the super capacitor can be firstly used for energy output or supplementary energyoutput, and after the power of the fuel battery rises, energy supply of the power battery and the super capacitor can be cut off; when the vehicle slides, the vehicle control unit sends the torque forrecovering the sliding energy to the driving motor system, the driving motor system recovers the sliding energy into the power battery and the super capacitor, and the same principle is adopted for recovering the braking energy.

    本发明公开了一种氢能源汽车多电源动力系统。本发明的燃料电池通过燃料电池升压器与第一高压配电箱电连接,动力电池和超级电容与第一高压配电箱电连接,第一高压配电箱与汽车的负载系统电连接,燃料电池、燃料电池升压器、动力电池、超级电容、第一高压配电箱和负载系统均与整车控制器电连接。本发明可以在车辆起步时,踩下油门踏板,此时可以先使用动力电池和超级电容进行能量输出或补充能量输出,在燃料电池功率上升起来以后,即可切断动力电池和超级电容的能量供应;在车辆滑行的时候,整车控制器发送滑行能量回收的扭矩给驱动电机系统,由驱动电机系统来实现将滑行能量的回收到动力电池和超级电容里面,制动能量回收也是同样的原理。
