These findings underscore the significant impact that the selection of flow channels and cooling fluids has on the thermal behavior of the battery. This study has demonstrated that liquid cooling with a curved channel configuration is an effective approach to enhance the thermal performance of LIBs employed in electric vehicles.
Dong et al. concluded from the numerical analysis of spiral channels that increasing the length and width of the channel first decreases and then increases the maximum temperature and temperature difference of the battery. In addition, increasing the height of the channel decays the thermal performance of the system.
An experimentally validated model of the battery was simulated for 100 different designs of the mini-channel to enable an extensive parametric survey. The influence of each cooling channel parameter on the thermal performance of the battery was investigated individually and then in combination with all other parameters.
Electric vehicle battery cooling channel design method was proposed. The cooling channel design usedDQN combining grid and CFD environments. A method of configuring the environment for better result of DQN was proposed. A new design can be generated for various target conditions through prior learning. 1. Introduction
The analysis clearly shows that the curved channel exhibits the highest OT among the three cases, with values of 305.03 K for air flow and 304.44 K for liquid flow. The minimum recorded OT was found to be 300 K. Consequently, the curved channel demonstrates superior cooling performance for battery cooling when compared to the other channels.
Mini-channels application in battery thermal management systems is wider than micro-channels. Here, applications of mini-channels in cooling rectangular (prismatic and bag model) and cylindrical batteries are discussed.
