6 FAQs about [New energy batteries are directly cooled]

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.

How does a battery cooling system work?

The system involves submerging the batteries in a non-conductive liquid, circulating the liquid to extract heat, and using an external heat exchanger to further dissipate it. This provides a closed loop immersion cooling system for the batteries. The liquid submergence and circulation prevents direct air cooling that can be less effective.

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.

Does a cooling strategy affect a battery cell?
