The invention discloses a fuel cell vehicle energy management method. The method comprises the following steps: determining power parameters of a whole vehicle, a fuel cell system and a battery; in the vehicle starting process, the whole vehicle required power and the residual electric quantity of the battery are detected in real time; judging whether the fuel cell system is started; according todifferent states of the fuel cell system; and sequentially judging the corresponding relationship between the residual electric quantity of the battery and a set threshold value and the correspondingrelationship between the whole vehicle required power and the power parameters of the fuel cell system, and respectively controlling the working states of the fuel cell system and the battery and outputting different powers according to different judgment results to realize the energy distribution of the fuel cell system and the battery. A reasonable control strategy is adopted, on the premise that the indexes of the whole vehicle are met, the electric quantity of the power battery can be reduced, the cost and weight of the whole vehicle are reduced, and the driving range of the whole vehicleis increased.
本发明公开了一种燃料电池汽车能量管理方法。它过程为确定整车、燃料电池系统和电池的功率参数,车辆启动过程中实时检测整车需求功率和电池的剩余电量,判断燃料电池系统是否启动,根据燃料电池系统的不同状态,依次判断电池的剩余电量与设定阈值之间、整车需求功率与燃料电池系统功率参数之间的对应关系,根据不同判断结果分别控制燃料电池系统和电池的工作状态及输出不同功率,实现燃料电池系统和电池能量分配。本发明采用合理的控制策略,在满足整车指标的前提下,可减少动力电池的电量,降低整车成本及车重,提高整车续驶里程。
