Analysis of the Cooling System in Battery Pack of Electrical Vehicles

Abstract

Many people are aware that our environment is getting worse from day to day due to air pollution, mainly from the on-road vehicles. To combat this problem, electric vehicles (EVs) such as hybrid electric vehicles (HEVs) and fuel cell hybrid electric vehicles (FCHEVs) were introduced. Cooling system for the battery pack in electrical vehicles is crucial, as the battery will have a poor performance if it is too hot. High temperature can cause fast aging of the battery. This review paper is to discuss the cooling system has an effect on the performance of the battery pack in electrical vehicles (EVs). From previous research findings and several methods can be used to solve this problem, either through simulations or experiments. Simulations usually run by computer software such as computational fluid dynamics (CFD) or finite element model (FEM) using mesh models. Most researchers prefer to choose simulations rather than experiments because it can save a lot of cost. As a result, battery pack in EVs needs to have cooling system, so that all the systems can run smoothly and efficient.
