Abstract

In recent years, the popularity of electric vehicles (EVs) has grown rapidly all over the globe. The passenger vehicles have seen a major shift from traditional internal combustion engines to EVs. One hurdle to EV adoption has been the risk of fire hazards in recent years. Such incidents have raised concern among buyers and slowed down EV sales. Modern EVs employ lithium-ion batteries due to their ready availability, cost-effectiveness, and improved performance. The only drawback of Li-ion batteries is temperature sensitivity. The performance of Li-ion batteries is significantly affected by extremely high or low temperatures. This is where the Battery Thermal Management System (BTMS) becomes relevant. BTMS is responsible for maintaining the battery pack temperature to optimise drive range, discharge rate, and other operational metrics.

BTMS technology has undergone significant improvements and developments over the past few years. Numerous studies have examined various cooling methods for EV batteries. The BTMS implemented in passenger EVs are either active, passive, or hybrid cooling systems. Each type of BTMS has its own advantages and disadvantages.

Selecting the appropriate BTMS is an important consideration when designing an EV. It has a direct impact on passenger safety and EVs overall performance. This review paper compares the applications and operating principles of various battery thermal management systems.
