A new study from the Chinese Academy of Sciences has measured how variations in individual cells within an electric vehicle battery pack directly limit overall performance. Researchers found that even minor inconsistencies in voltage, capacity, or temperature between cells can degrade efficiency and reduce the pack’s lifespan. The findings highlight a key challenge in maximizing battery reliability and energy output, offering potential insights for improving future EV designs. The research underscores the need for better cell-matching strategies to enhance real-world battery effectiveness.
