Recent Studies on Lithium-ion Battery Thermal Behaviour for Electric and Hybrid Electric Vehicles: A Review

Abstract

Environmental issues related to excess greenhouse gases have led to the introduction of electric (EV) and hybrid electric vehicles (HEV). The power source of these vehicles is mainly supplied from a battery specifically Lithium-ion battery (LIB). Lithium-ion battery possesses the characteristic of high power rating, high energy density, and high cycle life. However, this battery suffers from temperature problems, and thus battery thermal management (BTM) is crucial. This paper reviews the existing works related to lithium-ion battery thermal behaviours such as battery heat generation, battery temperature distribution and battery thermal management. Analysis of battery heat generation and temperature distribution is focusing more on single cell temperature behaviour. For battery thermal management, cooling systems such as air-based, liquid based and solid-based are reviewed but special attention has been putting on air-cooling type.
