Exploration of the Initial Cycle Aging Characteristics of High-Capacity Lithium Iron Energy Storage Batteries

Due to the influence of various factors on power, such as voltage fluctuations and load changes, these factors may lead to unstable power during the charging process, thereby increasing energy loss and reducing charging efficiency. Therefore, constant power cycle life testing has special significance and value for high-capacity energy storage batteries. This study, compared with traditional intermittent or low-power charge-discharge modes, more accurately reflects the real performance of energy storage batteries in working scenarios, providing important data for the long-term stability and reliability of the batteries.
