The battery cooling method using air as the medium is also called air-cooled cooling. According to whether the electric vehicle needs to provide auxiliary energy, it can be divided into active and passive heat dissipation methods.
Knowing the natural convection cooling performance of the battery module is the first step to investigate the thermal performance of the battery module. If the natural cooling performance is suitable for the stability and durability of the battery, there is no need for using forced air cooling strategy.
Overview of air-cooled cooling The thermal management of the power battery with air as the medium is to let the air traverse the battery pack to take away or bring heat to achieve the purpose of heat dissipation or heating. The battery cooling method using air as the medium is also called air-cooled cooling.
By changing the air inlet and air outlet, the temperature difference between different battery cells can be further reduced. Alternate ventilation is a heat dissipation method that cools the battery by periodically changing the position of the air inlet and the air outlet. The principle is shown in Figure 2.
Zhao et al. developed a heat pipe thermal management system with wet cooling which was able to control the temperature of battery pack in an appropriate temperature range . Air cooling method has the advantage of structure simplicity , light weight and low cost which the other BTMS may not have.
The heat exchange in the heat dissipation process of active air cooling is mainly forced convection. Therefore, if the space around the battery module allows, a local radiator or fan can be installed, or an auxiliary or car's own evaporator can be used to provide cold air. The principle is shown in Figure 1.
