摘要
为增强对复合电源电动汽车锂电池峰值电流抑制作用,加强对锂电池的保护,提出双模糊控制能量管理策略。基于AVL CRUISE软件平台搭建了整车模型,在MATLAB/Simulink中建立了能量管理控制策略模型,通过联合仿真验证控制策略的有效性。与基于规则和基于单一模糊控制能量管理策略对比,本文所提出控制策略有效降低了锂电池峰值电流,同时兼顾了高低功率区间的锂电池电流波动抑制目标,使得超级电容在汽车各需求功率区间内放电功率更加合理,更好地保护了锂电池。
In order to enhance the suppression effect on the peak current of lithium battery in hybrid storage electric vehicles and strengthen the protection of the lithium battery,a double fuzzy control energy management strategy is proposed in this paper.Based on the AVL CRUISE software platform,the vehicle model was built,and the energy management control strategy model was established in MATLAB/Simulink,and the effectiveness of the control strategy was verified by co-simulation.Compared with the rule-based and single fuzzy control-based energy management strategies,the control strategy proposed in this paper can effectively reduce the peak current of lithium batteries.At the same time,the lithium battery current fluctuation suppression targets in the high and low power range are taken into account,which makes the discharge power of the supercapacitor more reasonable in the required power range of the car,and the lithium battery is better protected.
