Optimization and Matching of Power Performance of New Energy Vehicles Based on Cruise
Objective:To optimize the dynamic performance of new energy vehicles and obtain the best speed ratio.Methods:Based on the vehicle simulation software Cruise,the driving motor,power transmission system and drive battery were selected through the existing parameters of new energy vehicles,and the model of new energy vehicles was built.Results:The power system of new energy vehicles was optimized and matched according to the vehicle power parameters of new energy vehicles.Conclusion:The optimal system parameters are permanent magnet synchronous motor,two speed transmission and secondary lithium battery.When the speed ratio is 13.066,the maximum climbing slope of the new energy vehicle is 52.28%and the driving range is 479.375 km.The dynamic performance of the vehicle can achieve the expected target results,saving time and cost for the early development and research of new energy vehicles.
