摘要
针对并联式混合动力汽车(Parallel Hybrid Electric Vehicle,PHEV)动力电池组单体电池存在不一致性的问题,通过对其现有的动力电池组充放电方法进行分析,以提高电池组均衡充放电效率,减少整体能耗为依据,提出了一种并联式混合动力汽车动力电池组实时均衡控制策略。利用常用的动力电池组进行了实时仿真,结果表明,与传统PHEV动力电池组实时充放电以及整体耗能方面相比,所提出的均衡控制策略有效地降低了能耗,延长了动力电池组的使用寿命,提高了PHEV动力电池组均衡充放电的效率。
In order to improve the efficiency of battery balanced charge and discharge and reduce overall energy consumption in Parallel Hybrid Electric Vehicle,this paper presents battery power real-time balance control strategy.The strategy not only can reduce overall energy consumption,but also can extend the service life of the power battery.The simulation results show the effectiveness of the proposed method.The results show that the presented method reduces the energy consumption and prolongs the life of the power batteries,improves the efficiency of battery charging and discharging for PHEV.
