Customer ServiceDifferent 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

However, extensive research still needs to be executed to commercialize direct liquid cooling as an advanced battery thermal management technique in EVs. The present review would be referred to as one that gives concrete direction in the search for a suitable advanced cooling strategy for battery thermal management in the next generation of EVs.
Because of the miniature thermal conductivity of air, the air-cooling battery thermal management system has low heat transfer efficiency and insufficient cooling capacity, so it cannot meet the cooling requirements of the battery when the battery is operating at high power.
An electronic expansion valve and a P–T sensor are added to the evaporator circuit and the battery cooling circuit, respectively, since the power battery cooling system needs to work together with the air conditioning system to achieve the cooling function.
