TL;DR: In this article , an overview of the research that has been conducted on thermal management of lithium-ion batteries utilizing heat pipes, liquid cooling, and phase change material cooling, which can be detailed classified as an active and passive thermal management system.
Abstract: AbstractIn the modern scenario of vehicle transit from internal combustion engine to electric vehicle there is a growth in battery technology. In an electric vehicle the cost of the battery cover 70% cost of the whole vehicle hence it is important to extract every cent of available energy present in it to delete very mileage of the vehicle. Climate change and pollution have created tremendous potential for the development of electric cars across the world. In comparison to conventional cars powered by internal combustion engines, the cycle life of the power battery, environmental adaptability, driving range, and charging time seem to be much worse. For this condition to be alleviated, effective battery thermal management (BTMS) is required. The purpose of this study is to provide an overview of the research that has been conducted on thermal management of lithium-ion batteries utilizing heat pipes, liquid cooling, and PCM (Phase Change Material) cooling, which can be detailed classified as an active and passive thermal management system. This article discusses how lithium-ion batteries generate heat and discusses important thermal problems. Then, many research on battery thermal management systems is examined in detail and classified according to their thermal functioning classification.KeywordsActive BTMSBTMSCFDPassive BTMSPCMReviewThermal runaway
