Air cooling systems, with their simpler design, are generally easier to maintain and have a lower risk of failure. Liquid cooling systems, while more efficient, require more maintenance and have a higher risk of leaks or other issues.
A lot of research has been conducted, forcing on developing new batteries [10, 11] and improving battery safety [12, 13], but the cooling system is still needed for the overall battery system. Generally, thermal runaway occurs when the heat losses to the environment do not offset the heat generated by exothermic reactions.
EV batteries can be cooled using air cooling or liquid cooling. Liquid cooling is the method of choice to meet modern cooling requirements. Let’s go over both methods to understand the difference. Air cooling uses air to cool the battery and exists in the passive and active forms.
The maximum temperature of the battery pack is always found in the middle cells of the pack; however, in traditional air-cooling directions, the middle cells of the battery pack do not receive optimal cooling. Therefore, this paper aims to enhance the efficiency of the air-cooling system by altering the direction of air cooling.
The choice of a battery cooling system depends on factors such as the type of battery, operational conditions, size and weight constraints, and cost considerations. Many electric vehicles and energy storage systems use a combination of these cooling methods to optimize performance and reliability.
By preventing excessive heat buildup, this cooling system significantly reduces the risk of battery fires and the release of toxic gases, thereby enhancing the safety of both the vehicle and its occupants. Another aspect of user safety is battery cell containment.
This need for direct cooling arises due to the significant heat generated by the high current flowing into the battery during fast charging. Effective battery cooling measures are employed to efficiently dissipate excess heat, thereby safeguarding both the charging rate and the battery from potential overheating issues.
