Exploration of Thermal Management Issues in the Battery Life Cycle

In order to comprehensively track and monitor battery performance across time domains and perform efficient thermal management. This article first summarized the research progress and status quo of battery aging models, and then coupled it with thermoelectric models to obtain the evolution of battery characteristic parameters during battery decay. From the perspective of the battery life cycle, it explored the thermal safety control and overheating prevention technology of power batteries, proposed a feed-forward heat management strategy, and took cooling measures in advance to prevent the increase in heat production caused by aging. The results show that the feed-forward thermal management strategy can ensure the cooling effect of the cooling system on the battery in the later stage of aging.
