Does a liquid cooling system work for a battery pack?
Computational fluid dynamic analyses were carried out to investigate the performance of a liquid cooling system for a battery pack. The numerical simulations showed promising results and the design of the battery pack thermal management system was sufficient to ensure that the cells operated within their temperature limits.
How does a liquid cooling system affect the temperature of a battery?
For three types of liquid cooling systems with different structures, the battery’s heat is absorbed by the coolant, leading to a continuous increase in the coolant temperature. Consequently, it is observed that the overall temperature of the battery pack increases in the direction of the coolant flow.
What is the cooling fluid flow rate of a battery pack?
When the cooling fluid flow rate of the battery pack is 0.03 m/s, 0.05 m/s and 0.07 m/s, the internal temperature difference and temperature rise of the battery pack after reaching the dynamic equilibrium are shown in Fig. 5.37, and the corresponding flow rates of the battery box are 7.2L/min, 12L/min and 16.8L/min respectively.
What is the temperature difference between a lithium ion battery and a battery pack?
As shown in Fig. 5.4, during 1C charging, the temperature of the lithium-ion battery pack increases from 20 to 24.5 ℃. As shown in Fig. 5.6, the surface temperature difference of the lithium-ion battery pack is high, and the temperature difference is close to 5 ℃.
What is the internal temperature difference and temperature rise of battery pack?
The internal temperature difference and temperature rise of the battery pack after reaching dynamic equilibrium at the cooling fluid flow rates of 0.03 m/s, 0.05 m/s and 0.07 m/s and the ambient temperature of 50 ℃ are shown in Fig. 5.42.
What happens if the battery pack temperature is optimized?
After optimization, the maximum temperature difference of the contact surface is only 3.45°C, the TSD is decreased, and the overall heat dissipation effect is improved. Fig 19. Temperature comparison of battery modules before and after optimization. (a) Initial battery pack temperature, (b) Optimized battery pack temperature. Fig 20.
