The invention discloses power equipment for a hydrogen fuel cell passenger car. The power equipment comprises a vehicle control unit, a drive axle, a hydrogen storage system and a drive motor. The power equipment is characterized in that a driving motor is connected with an automobile tire through a driving axle; a hydrogen storage system is connected with a hydrogen fuel cell stack, the hydrogenfuel cell stack is connected with a motor controller through a DCDC booster, the motor controller controls the driving motor to rotate, the motor controller is further connected with a power battery pack, and the power battery pack is connected with the hydrogen fuel cell stack through the BMS and the vehicle control unit. The hydrogen fuel cell provides continuous power independently or togetherwith power batteries, and the power batteries provide peak power when peak power requirements such as vehicle starting, climbing and acceleration are met; when the vehicle starting power demand is notlarge, the power batteries can independently output energy; braking energy recovery is completed by the power batteries; the power battery technology is mature, and the defects of the hydrogen fuel cell technology can be overcome to a certain extent.

    本发明公开了一种用于氢燃料电池客车的动力设备,它包括整车控制器、驱动桥、储氢系统、和驱动电机,其特征在于:所述驱动电机通过驱动桥与汽车轮胎连接,储氢系统连接到氢燃料电池堆上,氢燃料电池堆通过DCDC升压器与电机控制器连接,电机控制器控制驱动电机旋转,电机控制器还连接有动力电池组,所述动力电池组通过BMS和整车控制器与氢燃料电池堆连接。氢燃料电池单独或与动力电池共同提供持续功率,且在车辆启动、爬坡和加速等峰值功率需求时,动力电池提供峰值功率;在车辆起步功率需求量不大时,动力电池可以单独输出能量;制动能量回收由动力电池来完成;动力电池技术比较成熟,可以在一定程度上弥补氢燃料电池技术上的不足。
