Study on the Effects of Temperature and Configuration method on Battery Output Performance and Inconsistency

To meet the power demands of underwater vehicles, lithium batteries are typically configured in series and parallel arrangements to enhance their power and performance. Given the significant temperature variations across different marine environments, the performance of lithium batteries used in underwater vehicles is substantially affected by temperature changes. Additionally, After lithium batteries are assembled into a pack, inconsistencies can arise among the individual cells. This study employs ICR18650 cells to investigate the discharge performance and cell inconsistency of battery packs configured in various arrangements under different temperature conditions.
