Since the heat generation in the battery is determined by the real-time operating conditions, the battery temperature is essentially controlled by the real-time heat dissipation conditions provided by the battery thermal management system.
When the initial temperature of the battery decreases, the decreasing range of the battery temperature decreases. This is because the cold air outside takes away the heat inside the battery. And as the temperature difference between the battery and the environment decreases, the air carries less heat away.
Kim et al. (2014b) simulated the consequences of temperature variation and thermal runaway on the simple operation of a battery cell. These simulations assisted in the improvement of temperature regulation techniques and can be used in the design of BTMS; with improved battery performance by up to 58.4%.
Jeon (2014) projected the temperature dispersal within the cylindrical 18,650 battery cells using a transient thermo-electric model. The results indicated that the rise in temperature during the discharge cycle was greater than that during the charging cycle of the battery, but the difference decreased as C-rates increased.
Therefore, an effective and advanced battery thermal management system (BTMS) is essential to ensure the performance, lifetime, and safety of LIBs, particularly under extreme charging conditions. In this perspective, the current review presents the state-of-the-art thermal management strategies for LIBs during fast charging.
In both academia and industry contexts, static BTMS is traditionally employed to control battery temperature within an optimal range . To achieve superior temperature control performance, researchers have focused on enhancing the heat transfer efficiency of BTMS by appropriately selecting the operating medium.
