With the environmentally friendly development of modern technology, batteries have increasingly become an essential component of new energy sources, playing an increasingly significant role. Despite the rapid advancement in battery technology, the decline in performance of battery packs compared to individual cells in terms of cycle life remains a critical shortcoming. Traditional solutions typically focus on using complex thermal systems and management algorithms to extend battery life, often resulting in high costs and complex structures. This study proposes a novel and simple method, optimizing the lifespan of battery packs by rearranging them based on the relative size of internal resistance. Our experimental results demonstrate that this internal resistance-driven battery arrangement strategy avoids the need for expensive battery pack cooling systems and significantly enhances the overall cycle life of the battery pack, offering a new direction for the advancement and application of battery technology.
