Process of designing and optimization of an air cooled battery thermal management system contains some stages. First of all, each battery cell and adjacent fin has been simulated with an estimated mass flow rate of the coolant air to obtain an appropriate fin width. The flow rate assumed 5 cfm for the space between two battery cells.
In the battery cooling system, early research used a combination of heat pipes and air cooling. The heat pipe coupled with air cooling can improve the insufficient heat dissipation under air cooling conditions [158, 159, 160, 161], which proves that it can achieve a good heat dissipation effect for the power battery.
In air convection cooling, the low thermal conductivity and low specific heat capacity of air prevent it from lowering the maximum temperature and maintaining a uniform temperature in the battery pack when there is a lot of heat . However, battery performance is closely related to temperature .
The lower and main part of the battery pack is cooled by the circulating air flow that absorbs heat from battery cells. In this state each TE is simulated by a surface source which produces—50 kW heats. These results must be consistent with the previous results using the single cell and fin analysis.
While battery cooling remains essential to prevent overheating, heating elements are also employed to elevate the temperature of the battery in frigid conditions. This proactive heating approach assists in mitigating the adverse temperature effects on the electrochemical reactions, ensuring the battery can still deliver power effectively.
Passive air cooling involves air flowing from the outside to the inside of the battery pack, cooling the batteries because of the relative motion. As the vehicle moves, heat from the battery pack is removed by the air when passing through the gap in the battery pack and then vented from the opposite side.
