英文摘要:
Lithium battery state of Health (SOH) equalization technology is one of the key technologies to battery management system (BMS), which has attracted extensive attention of scholars. Therefore, this paper summarizes the current research on SOH equalization technology of lithium batteries. Firstly, this paper introduces the definition of SOH and the influencing factors of imbalance. Then, the published SOH equalization schemes for lithium batteries are classified and summarized, focusing on the principle, advantages and disadvantages of the current SOH equalization scheme. Finally, the future development and improvement direction of lithium battery SOH equalization technology are pointed out, in order to realize the SOH equalization of lithium batteries.
