What Causes Lithium-Ion Batteries to Overheat?
Different cooling methods have different limitations and merits. Air cooling is the simplest approach. Forced-air cooling can mitigate temperature rise, but during aggressive driving circles and at high operating temperatures it will inevitably cause a large nonuniform distribution of temperature in the battery, .
There are different methods available to maintain the ideal temperature in a battery pack for an electric vehicle (EV). Here are two of the most common EV cooling methods: 1.Air cooling: This method employs air to cool the battery.
