Conventional
fuels operated an internal combustion engines are the major sources of carbon
emissions and it causes environmental degradation. Electric vehicles (EVs)
offers best efficient and cost effective solution for the above said issue. By
year 2030 the world is aiming to shift to electric vehicles and one of the
hurdles in the path is thermal management in the battery. This study aims to
evaluate the performance of popular cooling methods thermodynamically. Lithium
–ion batteries are the most commonly used battery type in commercial electric
vehicles due to their high energy densities and ability to be repeatedly
charged and discharged over many cycles. In order to maximize the efficiency of
a li-ion battery pack, a stable temperature range between 15oC to 35oC
must be maintained. Battery thermal
management system (BTMS) plays a crucial role in enhancing the performance,
safety and lifespan of electric vehicle batteries by maintaining optimal
temperature conditions. This paper reviews how heat is generated across a
li-ion cell as well as the current research work being done on the four main
battery thermal management types which include air-cooled, liquid-cooled, phase
change material based and thermo-electric based systems. Additionally, the
strengths and weaknesses of each battery thermal management type is reviewed in
this study. It was determined that air cooled systems are suited for
short-distance travel electric vehicles, liquid cooled are for electric
vehicles that require long-distance travel, larger battery packs and for high
thermal loads, phase change material based are for electric vehicles with
constant thermal loads and stable ambient temperatures and thermo-electric
battery thermal management systems are best suited in conjunction with the
other types for better control.
