Why is cooling important when charging a car battery?

A substantial heat amount is generated during fast charging due to the high current flowing into the battery. If this heat isn't managed, it can impede the charging process or even cause damage to the battery. Effective cooling helps dissipate the excess heat, enabling faster and safer charging.

Is there a suitable cooling strategy for EV batteries?

There is a need to propose a suitable cooling strategy considering the target energy density of the EV battery which is expected to be attained in the future.

How to cool batteries during fast charging?

The core part of this review presents advanced cooling strategies such as indirect liquid cooling, immersion cooling, and hybrid cooling for the thermal management of batteries during fast charging based on recently published research studies in the period of 2019–2024 (5 years).

Why do EV batteries need cooling?

Effective battery cooling measures are employed to efficiently dissipate excess heat, thereby safeguarding both the charging rate and the battery from potential overheating issues. Furthermore, EV batteries may require heating mechanisms, primarily when exposed to extremely low temperatures or to enhance performance capabilities.

What are the benefits of a battery cooling system?

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.

Why does a battery need to be cooled?

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.
