高效率雙向電能回充主動式平衡電池管理系統

隨著鋰離子電池在電動車和儲能系統中的應用增加，電池管理系統在確保電池壽命與安全性方面變得至關重要。電池不平衡會降低容量與效率，甚至影響安全，因此電池平衡技術成為關鍵。相較於傳統的被動平衡透過電阻耗能，主動平衡透過能量轉移提高電池利用率，減少能量損失，並延長壽命。本文探討雙向電能回充主動式平衡技術，驗證平衡鋰電池不平衡狀況。結果顯示，主動平衡能有效縮短40 %以上的平衡時間，並提升系統能效至90 %以上，顯著減少能量浪費與發熱。未來結合智慧演算法與AI預測，將進一步提升效率，成為高效能電池管理的關鍵技術。

As the use of lithium-ion batteries in electric vehicles and energy storage systems increases, battery management systems become critical in ensuring battery life and safety. Unbalanced battery cells will reduce capacity and efficiency, and even affect safety, so battery balancing technology becomes critical. Compared to traditional passive balancing that consumes energy through resistance, active balancing improves battery utilization, reduces energy loss, and extends life through energy transfer. This article discusses the bidirectional energy recycling active balancing technology to verify the imbalance of balanced lithium batteries. The results show that active balancing can effectively shorten the balancing time by more than 40%, and improve the system energy efficiency to more than 90%, significantly reducing energy waste and heat. In the future, the combination of intelligent algorithms and AI predictions will further improve efficiency and become a key technology for high-performance battery management.
