The excellent temperature characteristics of space Li-ion batteries can effectively improve the on-orbit operation, reduce temperature fluctuation range and improve reliability. In this paper, the hardware-in-the-loop approach is used for simulation and experiment. This method cannot only effectively test the thermal management system of space battery, but also simulate the characteristics of the system in real-time to save high experimental costs. The results show that when the temperature of the inlet working fluid increases, the surface temperature increases significantly, with a maximum temperature difference of 4.9 °C. At the same time, the steady state settling time of the surface temperature also increases. When the flow rate of the inlet working fluid increases, the surface temperature decreases significantly. The maximum temperature difference is 3.9°C, and the steady state settling time of the surface temperature is greatly shortened. As the thermal load increases, the surface temperature of the battery increases obviously. The maximum temperature difference is 3.9°C, and the steady state settling time of the surface temperature is long. When the cycle is the same and the charge/discharge time is different, the longer the discharge time, the faster the surface temperature increases, up to 34%.

“…Studies are available that investigates the influence of liquid channels in prismatic batteries 34‐37 . Wang et al 38 proposed an electrochemical‐thermal coupling model to numerically predict the thermal behavior of the battery pack in different parameters of mini‐channel cold plates. The effects of cooling plate width, mini‐channel interval, and inlet mass flow rate on the heat dissipation performance of the system were analyzed at a constant C‐rate.…”

Summary In an electric vehicle, energy storage is in the form of electrochemical batteries, which are prone to thermal runaway and capacity fading if not maintained below safe temperature limits. An efficient battery cooling system is necessary for safer usage of electric cars during their life cycle. The current work presents a novel design that allows the coupling of liquid channels to a phase change material container in cylindrical batteries. The channeling approach allows heat dissipation from the phase change material container to both circulating media and convecting air. The design also helps to operate the cooling system without the circulation of liquid media in case of low ambient conditions. The comparison of the proposed system with a noncoupled liquid channel system is also presented to underline the merits of the system. The cooling media at a supply temperature of 30°C and the flow rate of 30 mL/min is adequate during the high ambient temperature of 40°C. The coupling of liquid channels to phase channel containers resulted in lowering the battery temperature well below 41.2°C even at an extremely high ambient temperature of 40°C.

“…Results show that maximum temperature of battery pack is negatively correlated with flow rate and positively correlated with inlet temperature. Wang et al [ 35 ] studied three straight‐channel LCPs placed at the bottom of prismatic battery packs. Results show that the increase in width of the cold plate and inlet mass flow rate can reduce maximum temperature and temperature difference.…”

Heat Dissipation Effects of Cavity Cooling Plate with Directly Opposite Inlet and Outlet on Lithium‐Ion Battery

Due to its high thermal sensitivity, a power lithium‐ion battery for vehicles requires an efficient cooling system to ensure safety and good performance. Excellent heat dissipation capacity enables the liquid cold plate cooling system to have better application prospects. However, all existing cold plates improve their cooling capacity by increasing the complexity of their structure. Therefore, directly opposite inlet and outlet cavity cold plate cooling systems with simple structures are established. Two kinds of cavity cold plates (Model I and Model L) with different inlet and outlet positions are analyzed using the numerical simulation method. The effects of inlet and outlet sizes, coolant mass flow rate (qm), and inlet and outlet positions on the temperature field as well as the cold plate pressure drop are studied. According to the results, maximum temperatures of batteries appear at four corners of cavity cold plates, which are lower than 35 °C. The cooling capacity and temperature uniformity of Model I cooling systems are better than those of Model L. However, the heat dissipation capacity of Model L is more sensitive to qm than that of Model I. Pressure drop of Model L is smaller. This method meets the heat dissipation of vehicle pouch lithium‐ion batteries.
