Study on direct refrigerant cooling for lithium-ion batteries of electric vehicles

When comparing base paths for converting to renewable energy with conventional based routes, electric vehicles (EVs) offer the most efficient and affordable solution for the aforementioned problem. EVs use lithium‐ion batteries to store energy, but these batteries face an array of difficulties, includes poor performance at both high and low temperatures, high temperature electrode life reduction and thermal runaway safety worries. These issues have a direct impact based on performance, dependability, cost, and security of the vehicle. For Lithium‐ion (Li‐ion) battery packs used in Electric Drive Vehicles (EDVs), selecting the best cooling technique and developing an effective cooling control strategy are crucial for enhancing security, increasing the pack's validity, and decreasing expenses. The appropriate range of temperatures for such battery packs range between 15°C and 35°C. Trade‐offs must be regarded when deciding how to cool and creating strategies, including those involving prices, complexity, weight, cooling results, homogeneity of temperature, and parasitic power. The batteries may be fatally destroyed if they overheat due to chemical reactions triggered by the flow of electrons during the charging and discharging operation in hot temperatures. Therefore, numerous thermal management of batteries system types as well as potential for progress are explored in this evaluation study. The Battery Thermal Management Systems (BTMS) for electric vehicles has a lot of room for further research, it is concluded. Temperature regulation of lithium‐ion batteries is challenging due to the weak heat resistance of lithium ions. The internal working temperature significantly affects influence on the functionality and lifespan of lithium‐ion batteries. To guarantee a Li‐ion batteries reliable performance for a given application, battery cell thermal characterization is crucial. Due to the high heat that commonly used Lithium‐ion (Li‐ion) batteries produce during fast charging and discharging, Thermal Management Systems (TMS) are necessary for the operation of electric cars. In this paper, an experimentally verified OHP system is suggested as a module for cooling batteries.
