Review on Current Thermal Issue and Cooling Technology Development on Electric Vehicles Battery

As one of the most prominent parts of an electric vehicle, Li-ion battery has been widely used as the main power source of the vehicle. However, this battery is very sensitive to the working temperature. Some thermal issues can occur when the temperature of the battery exceeds the maximum allowable working temperature of a battery. Thus, a proper battery thermal management system is required in order to support electric vehicle performance. In this paper, some problems which can occur during overheating are explained. Then, the current development of the battery thermal management system based on the cooling mechanism as well as the cooling mode is reviewed together with the merits and demerits of each model. Lastly, brief comparisons between the systems are explained as the conclusion of the most promising battery thermal management system in the future.
