The battery thermal management system has become an important aspect of the development of electric vehicles (EVs) which are widely considered as a promising option instead of internal combustion based vehicles (ICEs) for reducing the climate change effects. Particularly, advances in Lithium ion batteries with high energy density are considered key elements for wide spread acceptance of EVs. Batteries with larger energy densities exhibit the thermal issues, which creates decreased performances at higher operating temperatures and eventually turning thermal runaway into fire or explosion. In this paper, a novel design is presented with mineral oil as a coolant with channel guide. The temperature distribution is recorded at various coolant mass flow rates and pressure drop variation is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
