The invention discloses a hydrogen fuel cell series-parallel hybrid power system. A hydrogen fuel cell is electrically connected with a motor controller through a DC/DC converter; and the motor controller is electrically connected with the driving motor. The invention further discloses a truck adopting the power system. By adopting the technical scheme, the total energy of the power system is improved, the endurance mileage is increased, and the utilization effect of energy utilization is improved; the cost of the whole vehicle is greatly reduced, the working efficiency of the fuel cell is relatively high, the performance requirement is relatively low, and the cold start performance is relatively good; the power battery not only recovers braking energy, but also generates electricity by utilizing the generator, so that more electric quantity can be stored quickly; the lasting time of the peak power of the generator is long, long-distance pure electric driving is achieved, and more energy is recycled; and the short dynamic property and the economical efficiency are high.

    本发明公开了一种氢燃料电池混联式混合动力系统,氢燃料电池通过DC/DC转换器与电机控制器进行电气连接;电机控制器与驱动电机采用电气连接。本发明还公开了采用该动力系统的卡车。采用上述技术方案,提高电力系统总能量,增大续航里程,提高能量利用的利用效果;大大降低整车成本,燃料电池工作效率较高,性能要求较低,冷启动性能较好;动力电池不仅回收制动能量,还利用发电机发电,储存电量较快较多;发电机峰值功率持续时间长,实现长距离的纯电行驶,回收更多能量;短动力性和经济性较高。
