Research on Heat Dissipation Characteristics and Flow Field Simulation of Electric Vehicle Power Battery Pack
ABSTRACT
With the increasingly serious ecological and fossil energy issues, the traditional fuel vehicles with high pollution and high energy consumption has become an important issue that can not be ignored. However, EVs can effectively solve these problems and meet the requirements of social development in the new era, thus becoming the general trend of the automobile industry.
Pure electric vehicle battery thermal management problems, especially battery cooling problem has been the core issue of pure EV design and research, a good battery cooling system can effectively improve the driving range of pure electric vehicles, life, power And economy, to ensure the safety of pure electric vehicles. In this paper, Ansys Fluent is mainly used to simulate the flow field of three-dimensional model of power battery packs with different arrangement methods. Through the comparative analysis of the results, the cooling structure is properly designed. This can effectively improve the performance of electric vehicles.
