The invention discloses a hydrogen fuel power system for a telescopic boom forklift, a control method, a fuel cell controller and the telescopic boom forklift. The hydrogen fuel power system comprises a hydrogen fuel cell system and a lithium battery. When the telescopic boom forklift is started, the lithium battery supplies power independently; after the hydrogen fuel cell system reaches the starting temperature, the current whole vehicle required power and the lithium battery SOC are obtained; adjusting the output power of the hydrogen fuel cell system and the lithium battery in real time according to the current required power of the whole vehicle and the SOC of the lithium battery in combination with the efficient working interval of the hydrogen fuel cell system and the SOC range of the lithium battery; when the telescopic arm forklift brakes, the lithium battery recovers braking energy generated by the motor. The lithium battery and the fuel battery are combined, and the running state and energy distribution of the vehicle are controlled, so that the lithium battery and the fuel battery work in a high-efficiency interval, the dynamic property of the whole vehicle is met, the use efficiency of the lithium battery and the fuel battery is improved, and the service life of the fuel battery is prolonged.
本发明公开了一种伸缩臂叉车用氢燃料动力系统、控制方法、燃料电池控制器及伸缩臂叉车。氢燃料动力系统包括氢燃料电池系统和锂电池。伸缩臂叉车起步时,由锂电池单独供电;待氢燃料电池系统到达启动温度后,获取当前整车需求功率和锂电池SOC;根据当前整车需求功率和锂电池SOC,结合氢燃料电池系统的高效工作区间和锂电池的SOC范围,实时调节氢燃料电池系统和锂电池的输出功率;当伸缩臂叉车制动时,由锂电池回收电机产生的制动能量。本发明将锂电池和燃料电池结合起来,通过对车辆的运行状态和能量分配进行控制,使得锂电池和燃料电池工作在高效率区间,满足整车动力性的同时,提高了锂电池和燃料电池的使用效率,延长了燃料电池的使用寿命。
