Battery Thermal Management Systems For Electric Vehicles

Abstract

A large part of the automotive industry consists of internal combustion engine vehicles. However, due to the exhaustion of oil, increasing energy needs and environmental pollution, alternative energy sources have been sought. Therefore, interest in renewable energy and environmentally friendly vehicles is increasing. For this purpose, electric vehicles, which are more efficient than internal combustion engine vehicles, are being developed. One of the most important components of electric vehicles is the battery. It is known that battery systems are affected by temperature. At temperatures outside of the battery's efficient operating range, energy and power capacity and lifespan considerably reduced. This situation necessitates an effective battery management system for the increasing number of electric vehicles in the market. In this review, the situations that may occur due to the heat generation of the battery during rapid charge and discharge and the solutions that can be done to prevent these situations are examined and discussed. Thereby battery thermal management systems are explained and the working principles of these systems are emphasized.
