We have lots of design and manufacturing experience. We offer a wide range of products and designs. We are not just for cooling batteries. We are also for energy storage, high heat flow, and new liquid cooling tech. This expertise ensures that modern electric vehicles'' thermal needs are met well. It fixes the limits of earlier passive cooling.
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%.
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 optimal operating temperature range for these power batteries was found to be between 25–40 °C, and the ideal temperature distribution between batteries in the battery pack should be below 5 °C . Sato pointed out that when the battery temperature is higher than 50 °C, the charging speed, efficiency, and lifespan are reduced.
The T max of the battery is kept within 35 °C when the inlet mass flow rate of the LCP work fluid is 5 × 10 −4 kg·s −1. The proposed BTMS reduces the T max in the battery below 35 °C and improves the temperature homogeneity with a Tv of no >1 °C between cells in the battery pack under 600 s of discharge and charge cycling at a rate of 4C.
Some new cooling technologies, such as microchannel cooling, have been introduced into battery systems to improve cooling efficiency. Intelligent cooling control: In order to better manage the battery temperature, intelligent cooling control systems are getting more and more attention.
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.
