Increasing the coolant’s inlet temperature effectively reduced the temperature difference between the upper and lower battery sections, resulting in reductions of 1.5 K and 4.3 K for fin cooling and PCM cooling, respectively, using the bottom cooling plate.
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.
Fig. 16 shows the trajectory of the battery temperature and the coolant temperature in the battery for the cooling mode over a variety of driving cycles and an environment temperature of 40 °C. In cooling mode, the coolant carries the heat generated by the battery from the battery to the radiator and dissipates the heat to the environment.
Through the numerical analysis, comparison was carried out to find out the performance of the proposed internal cooling scheme with external cooling scheme. The internal cooling scheme can not only reduce the maximum internal temperature of the battery, but also improve the temperature uniformity between the batteries.
Combining other cooling methods with air cooling, including PCM structures, liquid cooling, HVAC systems, heat pipes etc., an air-cooling system with these advanced enhancements should provide adequate cooling for new energy vehicles’ high-energy battery packs.
According to the above analysis, the battery liquid cooling is a promising cooling method (see Fig. 20). Among all coolants, water and oil are easy to obtain and have low prices. They are widely used and the most promising coolant. Fig. 20. Schematic of liquid cooling battery module .
