Treffer: Optimal Structure Design and Temperature Control Strategy of Air‐Cooled Battery Thermal Management System.

Safety concerns in lithium‐ion batteries pose significant challenges for electric vehicle systems. A reliable battery thermal management system is essential to maintain optimal battery performance. In this article, simulation is carried out for the design of air‐cooled battery packs with aligned, equally spaced staggered, and nonequally spaced staggered arrangements, based on experimental validation. The battery spacing and positioning are optimized based on cooling and heating conditions to determine the optimal heat dissipation configuration. The results reveal that staggered arrangements enhance heat transfer, with the nonequally spaced configuration reducing the maximum temperature difference by 15.6% and energy consumption by 36.6%, compared to the equally spaced staggered setup. Furthermore, considering the control demands of battery pack temperature and wind speed, the state equation for model predictive control of the battery pack is constructed and solved by particle swarm optimization algorithm. Subsequently, cosimulation is employed to verify its effectiveness. The proposed strategy efficiently regulates battery temperature and reduces energy consumption, demonstrating its potential for improving battery thermal management in practical applications.
