How to deal with the heating of the battery in the energy storage cabinet

How important is battery temperature management?

As applications become more powerful and more prevalent, managing battery temperature is no longer a design afterthought, it’s a critical system-level priority. Thermal management plays a key role in ensuring battery safety, performance, lifespan and charging efficiency. But how do we choose the right cooling strategy?

Is air cooling a viable solution for a battery system?

Despite its drawbacks, air cooling remains a viable solution when simplicity, low cost and ease of integration outweigh the need for high thermal precision. Liquid cooling is one of the most widely adopted thermal management strategies for modern battery systems due to its excellent balance of performance and practicality.

How does a battery cooling system work?

It uses a liquid coolant, typically a water-glycol mixture, that flows through channels or cold plates integrated within or around the battery pack. This method offers significantly higher heat transfer capacity compared to air cooling, resulting in more uniform cell temperatures, improved battery efficiency and extended lifespan.

Does air cooling affect battery performance?

However, air cooling has significant performance limitations. Its low heat transport capacity can lead to uneven temperature distribution across cells, which affects battery efficiency, degradation and overall safety.
