摘要
为了提高燃料电池汽车的经济性和燃料电池的效率,基于模糊控制理论,提出以减少燃料电池频繁启停为目标的能量管理策略。将这一策略与通用的功率跟随策略在UDDS循环工况下进行对比,结果表明:模糊控制策略能够满足实际工况的功率需求;燃料电池在1369 s的时间内启停次数由7次降为0次;整车的经济性提高了3.5%。研究成果可为燃料电池汽车的能量管理策略的制定提供参考。
In order to improve the fuel cell vehicle economy and fuel cell efficiency,an energy management strategy with the goal of reducing frequent start and stop of fuel cells is proposed based on fuzzy control theory.Comparing this strategy with the general power following strategy under UDDS cycle conditions,the results show that:the fuzzy control strategy can meet the power requirements of the actual conditions,the number of fuel cell starts and stops in 1369 s is reduced from 7 to 0 times.The economy of the entire vehicle has increased by 3.5%.The research results can provide a reference object for the development of fuel cell vehicle energy management strategy.
