"Calibration and Validation of Equivalent Circuit-Based Battery Models for Thermal Analysis "
Vehicle manufacturers are rapidly electrifying their vehicle fleets, making thermal-electrical component modeling increasingly critical in the design of on-board thermal management systems. Problems surrounding thermal management are amongst the largest challenges faced by electric vehicle and hybrid electric vehicle designers today, especially when it comes to battery packs. Batteries have a small safety envelope for thermal environment, and the overall performance and lifetime of a battery pack is largely determined by the thermal conditions that the batteries are subject to. In addition to the average temperature of a pack, thermal gradients between cells and within individual cells also determine the performance of the pack and how long it will last. Detailed thermal models of batteries are required for heating and cooling system design, which must be calibrated using both electrical and thermal test data.
