A system with an effective control strategy is proposed for battery cooling. The J-type, U-type and L-type flow types are integrated in the system. Uneven parallel channels widths are designed to improve the system performance. Air-cooled systems are widely used in electric vehicles for the thermal management of battery packs.
Conclusions In this study, a parallel air-cooled system with a designed control strategy is developed for efficient cooling of battery packs under varying operating conditions. The performance of the systems with different flow types is studied numerically. The simulation results are verified by experiments.
8. Outlook Within the scope of this review, the concept of air cooled battery thermal management systems for electric vehicles have been presented. Classification criteria of all other BTMS methods have been briefly highlighted; while benefits and drawbacks of air cooled BTMS in comparison with other EV cooling strategy have been discussed.
By preventing excessive heat buildup, this cooling system significantly reduces the risk of battery fires and the release of toxic gases, thereby enhancing the safety of both the vehicle and its occupants. Another aspect of user safety is battery cell containment.
Thus, switches of different flow types will be anticipated to cool the high-temperature battery cells with more air and improve the temperature uniformity in the battery pack.
Uneven parallel channels widths are designed to improve the system performance. Air-cooled systems are widely used in electric vehicles for the thermal management of battery packs. Due to the low specific heat capacity of air, design of air-cooled systems is required to improve the temperature uniformity of battery packs.
