Design and Simulation Analysis of a Power Battery System Based on PHEV
To meet the requirements of a PHEV model from a car company,a battery system was designed. The structural composition of the battery system and the thermal management system were introduced,and the simulation analysis of the mechanical properties and thermal management performance of the system were conducted. It was found that the first-order modal values of the battery box and cover were both smaller than the target. The simulation and analysis of pack flow resistance characteristics and heating performance in low temperature conditions were carried out for the battery system,and the results showed that the performance indexes met the design requirements.
