The simulation model is validated by the experimental data of a single adiabatic bare battery in the literature, and the current battery thermal management system based on immersion cooling can effectively improve the heat dissipation of the battery module.
Battery pack heat dissipation, also called thermal management cooling technology plays a key role in this regard. It involves the transfer of internal heat to the external environment via a cooling medium, thereby reducing the internal temperature.
At present, the common lithium ion battery pack heat dissipation methods are: air cooling, liquid cooling, phase change material cooling and hybrid cooling. Here we will take a detailed look at these types of heat dissipation. 1. Air cooling
Air cooling Air cooling, mainly using air as the medium for heat exchange, cools down the heated lithium-ion battery pack through the circulation of air. This is a common method of heat dissipation for lithium-ion battery packs, which is favoured for its simplicity and cost-effectiveness.
The static cooling medium cannot dissipate heat in time, resulting in the elevated but slightly different temperature for all the batteries. The increasing flow rate can monotonously reduce the battery temperature, but impose distinct impacts on the temperature uniformity of the system.
