Nowadays Electric vehicles (EV) develop fast in current market and have become popular due to its zero emission and high efficiency .However there are many factors to limit its performance, cost, lifetime and safety of battery. So, the management of batteries is necessary to increase its performance when operating at various conditions. The battery thermal management system (BTMS) is introduced to control the thermal behaviour of batteries. In this paper we will see about BTMS technologies such as air cooling system, liquid cooling system, direct refrigerant cooling system, phase change material (PCM) cooling system. These systems are analysed through their performance, weight, size, and cost
