Parameters optimization and performance simulation for parallel hybrid electric vehicle

Meilan Zhou, Hao Zhang, Zhaoming Gao

Open publisher page 1 citations

Abstract

Aiming at the hybrid electric vehicle (HEV) low-emission and fuel-efficient advantages, the original model vehicle is refit into parallel hybrid electric vehicle (PHEV), and its power system parameters are designed. The dynamic performance, fuel economy and battery state of charge (SOC) on the NEDC typical driving cycle are simulated by hybrid electric vehicle simulation software ADVISOR. The comparisons between the simulation results of two models show that the modified HEV is better than the original model on fuel economy, the dynamic performance is basically unchanged, and the charge-discharge characteristics of battery achieve a balance on driving cycle, so the design of power system parameters is reasonable.
