Energy Management Strategy Design for Double Fuzzy Control of Hybrid Storage Electric Vehicle
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.
