In addition, it offers exceptional flowability and helps battery designers achieve thinner parts than possible with incumbent battery module insulation materials, such as polycarbonates or aerogels. It has been successfully tested with plates molded in typical dimensions of 100 x 150 x 0.5 mm.
The power battery is an important component of new energy vehicles, and thermal safety is the key issue in its development. During charging and discharging, how to enhance the rapid and uniform heat dissipation of power batteries has become a hotspot.
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.
There is a general belief that the battery pack should not have a temperature difference exceeding 5 °C . Figure 6. (a) Schematic diagram of the experimental setup, and (b) comparison cycle life performance . 3. Air Cooling Technology Battery packs are normally cooled with air cooling technology.
Currently, the commonly used models for battery heat generation are electrochemical-thermal models and electrical-thermal models. The electrochemical-thermal models rely on the electrochemical process occurring within the battery, taking into account the impact of internal chemical reactions on heat production.
In addition to liquid cooling, heat pipes can help make up for the low specific heat capacity of air. Using CHP, Behi et al. proved that the liquid-cooling-coupled heat pipe system outperforms an air-cooling-coupled heat pipe system in terms of cooling effect, and the maximum temperature of the battery is reduced by about 30%.
