Electric vehicles are better for the environment. Lithium-ion (Li-ion) battery cells can be used as energy storage. Some uses of the battery are not only used as a power supply for electric motors but are also used in supporting systems such as an additional braking system using Eddy Current Brake (ECB). In general, ECB requires a large current when starting the braking process. At this early stage, the heat will be generated relatively high. During operation, heat is generated, and it will burden the battery's performance. Thus, the heat generated needs to be released into the environment. Careless heat management can have multiple effects, such as fire and, in the worst case, explosion. Battery Thermal Management System (BTMS) needs to be implemented in electric vehicles. There are several methods of thermal management, such as air-cooled and liquid-cooled. The results show that liquid-cooled BTMS is superior in uniform but more complex temperature distribution, and liquid leakage may occur. In comparison, air-cooled BTMS has the advantage of a more accessible system, but the temperature distribution between batteries is not good. Air Cooler can maintain the ideal battery temperature between 20-40 °C.
