The invention provides an energy management method for a hydrogen energy fuel-cell vehicle. A program which is composed of data codes and can run according to a certain algorithm is inputted into an integrated circuit unit capable of conducting information and data processing; and the algorithm of the running program is as follows: the output power of the fuel cell should be the sum of the net output electric quantity of the cell in the last time period and a power output deviation value of the fuel cell in the first two time periods. With the method, the fuel cell can stably carry out outputting, and the service life of the fuel cell is prolonged; meanwhile, the SOC of the matched battery can fluctuate within a small range, and the service life of the battery is prolonged. Therefore, thepower distribution quantity of the whole vehicle can be reduced, the cost of the whole vehicle is lowered, and the competitiveness is improved.
本发明提供了一种针对氢能燃料电池车的能量管理方法,在可进行信息和数据处理的集成电路单元内灌入数据代码组成的可按一定算法运行的程序,该运行程序的算法为燃料电池应该输出功率为上一时段电池的净输出电量加上前两个时段的燃料电池的功率输出偏差值。通过采用本方法,可使燃料电池稳定输出,延长燃料电池的使用寿命;同时可使配套的电池的SOC在小范围波动,延长电池的使用寿命。通过采用本发明的方法,可以降低整车的配电量,降低整车成本,提高竞争力。
