The invention provides a vehicle fuel cell operation power control system and method. The system comprises a fuel cell management unit, a vehicle control unit, a power cell management unit, and a motor controller, wherein the power cell management unit, the motor controller, and the fuel cell management unit are respectively connected with the vehicle control unit. The vehicle controller controlsthe fuel cell to follow the power of the vehicle motor to a certain extent according to the motor bus voltage and the motor bus current; and the SOC is monitored and the operation power of the fuel cell is dynamically adjusted, so that the power cell is prevented from being overcharged and overdischarged, the SOC is maintained in an optimal service life working interval, and the service life of the power cell is prolonged.

    本发明提供一种车用燃料电池运行功率控制系统及方法,所述系统包括:燃料电池管理单元、整车控制器、动力电池管理单元和电机控制器,所述动力电池管理单元、电机控制器和燃料电池管理单元分别与整车控制器连接;本发明的整车控制器根据电机母线电压、电机母线电流控制燃料电池在一定程度上跟随整车电机功率;监控SOC并动态调整燃料电池运行功率,保证动力电池不过充、不过放,使得SOC维持在一个最佳寿命工作区间,延长动力电池寿命。
