On the Optimization of New Energy Automobile Power System

In order to optimize the power control system of new energy vehicles,based on the design parameters of new energy vehicles, the simulation analysis model is established.In view of the design of switched reluctance drive motor and the selection of regenerative battery, this paper puts forward the problem, and studies the characteristics of battery capacity in influencing new energy vehicles.And according to the actual state of the new energy vehicle cycle control system operation, the new energy vehicle battery parameters optimization scheme is proposed to improve the efficiency of the battery, and by introducing the quality ratio coefficient of the battery’s charged state, the design of charging monomer specification capacity and combined capacity is comprehensively optimized.Aiming at simultaneously improving the power and economic performance of new energy vehicles, optimize the setting of vehicle driveline ratio from the overall aspect, and then carry out simulation analysis on this scheme.This is of great significance for improving the dynamic performance of new energy vehicles and increasing the operating mileage of new energy vehicles.
