The invention discloses a multi-power-supply power system of a hydrogen energy automobile. The system comprises a fuel cell, a power cell and a high-voltage distribution box. The fuel cell is electrically connected with the high-voltage distribution box through the fuel cell booster, the power cell is electrically connected with the high-voltage distribution box, the high-voltage distribution boxis electrically connected with a driving motor system of the automobile, and the fuel cell, the fuel cell booster, the power cell, the driving motor system and the high-voltage distribution box are all electrically connected with the whole automobile controller. The power battery is added to serve as auxiliary energy, when the vehicle is started, an accelerator pedal is stepped down, the power battery is firstly used for outputting energy or supplementing energy to solve the problem that the power performance of the whole vehicle is insufficient, and when the vehicle slides, the whole vehiclecontroller sends torque recovered by sliding energy to the driving motor system to control the driving motor system to drive the vehicle to slide. The driving motor system controls the motor to achieve recovery of sliding energy, the energy is recovered into the power battery, and braking energy recovery is also the same principle.

    本发明公开了一种氢能源汽车多电源动力系统。本发明包括燃料电池、动力电池和高压配电箱;燃料电池通过燃料电池升压器与高压配电箱电连接,动力电池与高压配电箱电连接,高压配电箱与汽车的驱动电机系统电连接,燃料电池、燃料电池升压器、动力电池、驱动电机系统和高压配电箱均与整车控制器电连接。本发明增加了动力电池作为辅助能源,可以在车辆起步时,踩下油门踏板,先使用动力电池进行能量输出或补充能量输出,来解决整车动力性不足的问题,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,由驱动电机系统控制电机来实现对滑行能量的回收,能量回收到动力电池里面,制动能量回收也是同样的原理。
