Air and PCM cooling for battery thermal management considering battery
The study shows that active air cooling has a better cooling effect than PCM cooling, especially at high ambient temperatures. But the active air cooling leads to a large temperature non-uniformity at low inlet air velocities. The cycle life of the battery module under air cooling is longer than that of PCM cooling, although a larger life non-

What is battery cooling method?
The battery cooling method using air as the medium is also called air-cooled cooling. According to whether the electric vehicle needs to provide auxiliary energy, it can be divided into active and passive heat dissipation methods.
What is air-cooled cooling?
Overview of air-cooled cooling The thermal management of the power battery with air as the medium is to let the air traverse the battery pack to take away or bring heat to achieve the purpose of heat dissipation or heating. The battery cooling method using air as the medium is also called air-cooled cooling.
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.
How does a cooling system affect a battery?
A liquid or air cooling system must manage this elevated heat without compromising safety or performance. Fast charging also demands cooling systems capable of rapidly dissipating generated heat to prevent overheating, a factor that could undermine battery longevity and safety.
Is air cooling a good way to cool a battery pack?
Air cooling through natural ventilation is the cheapest and most simplistic mode of cooling for a battery pack but it does not provide sufficient cooling for most EV applications due to its low heat capacity and heat transfer coefficients .
