The optimal operating temperature range for these power batteries was found to be between 25–40 °C, and the ideal temperature distribution between batteries in the battery pack should be below 5 °C . Sato pointed out that when the battery temperature is higher than 50 °C, the charging speed, efficiency, and lifespan are reduced.
In order to ensure the safety of electric vehicles in high and low temperature environments, improve the performance of electric vehicles and the service life of power battery packs, power battery thermal management technology has been widely emphasized by major automobile companies.
To conduct the heat efficiently, the heat spreaders may be placed between batteries to enhance the heat transfer from the module to the cold plates. Because of the flat shape, the cold plates are widely used in battery module, consisting of prismatic cells instead of cylindrical cells.
In addition to liquid cooling, heat pipes can help make up for the low specific heat capacity of air. Using CHP, Behi et al. proved that the liquid-cooling-coupled heat pipe system outperforms an air-cooling-coupled heat pipe system in terms of cooling effect, and the maximum temperature of the battery is reduced by about 30%.
