Simulation Test Method for Battery Dynamic Performance of Double Battery Hybrid Electric Vehicles

Abstract

The dynamic performance, effective life and output reliability of electric vehicle battery have a direct impact on the dynamic performance of electric vehicle. Based on the force analysis of different conditions of electric vehicle load, this paper builds a battery performance test platform for double battery hybrid electric vehicle, which includes DC servo motor as battery-driven active traction motor, AC servo motor as load resistance motor to provide different conditions and PLC control system. The platform can adapt to different vehicle models, conditions and achieve traction power simulation, load conditions simulation in order to experimentally analyze the battery dynamic performance. At the same time, the simulation analysis of the same driving conditions by ADVISOR2002 verifies the consistency with the simulation test method, which shows that the simulation test method can effectively evaluate the battery performance of electric vehicles. This provides an effective way to improve the battery performance of electric vehicles.
