Comparison of different cooling methods for lithium ion battery
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 [26], [27].Nevertheless, in some cases, such as parallel HEVs, air
