Electric vehicles (EVs) necessitate an efficient cooling system to ensure their battery packs' optimal performance, longevity, and safety. The cooling system plays a critical role in maintaining the batteries within the appropriate temperature range, which is essential for several reasons we'll review in detail below.
Anisha et al. analyzed liquid cooling methods, namely direct/immersive liquid cooling and indirect liquid cooling, to improve the efficiency of battery thermal management systems in EVs.
