Learn More8. 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.
Air cooling is one of the most commonly-used solutions among various battery thermal management technologies. In this paper, the cooling performance of the parallel air-cooled BTMS is improved through choosing appropriate system parameters.
The cooling air flows into the battery pack from the inlet. After splitting in the wedge-shaped Divergence Plenum (DP), the air enters the Cooling Channel (CC) to take away the heat generated by the battery and then flows out of the battery pack after converging in the wedge-shaped Convergence Plenum (CP).
Air cooling through natural ventilation is the cheapest and most simplistic mode of cooling for a battery pack but it does not provide sufficient cooling for most EV applications due to its low heat capacity and heat transfer coefficients .
Yu et al. developed a three-stack battery pack with the stagger-arranged Lithium-ion battery cells on each stack with two options: natural air cooling and forced air cooling as shown in Fig. 2. The experimental results showed that the active air cooling method could reduce the maximum temperature significantly. Fig. 2.
Effective battery cooling measures are employed to efficiently dissipate excess heat, thereby safeguarding both the charging rate and the battery from potential overheating issues. Furthermore, EV batteries may require heating mechanisms, primarily when exposed to extremely low temperatures or to enhance performance capabilities.
