The efficiency of the battery thermal management system (ThMS) can be used to assess the performance and safety of electric vehicles. Heat is produced by high battery discharge/charge current. Controlling battery heat quickly and effectively is crucial to preventing battery deterioration or even fire. Different BThMS were experimentally investigated in both cruising and vehicle acceleration modes. By keeping an eye on the battery’s temperature between 30 and 40 °C in both the state of charge (SoC) and the state of discharge (SoD), smart evaporative BThMS is advised for maximizing battery performance. To regulate battery temperature and extend battery life, an algorithm was created based on the LIB temperature range.
