在鋰離子電池的使用中，電池老化一直是令人詬病的缺點，而其
中影響老化程度最大的即是充電技術。現今可降低鋰離子電池老化程
度的充電技術中，其多半是在充電時間、電流大小、充入容量、電池
溫升以及使用壽命之間做權衡，進而達到延緩老化的目的。對此本文
提出定電流-複合弦波電壓的充電策略，透過在充電過程之定電壓段
給予一放電區間，達到回復鋰離子電池健康度的目的，同時透過找尋
鋰離子電池交流阻抗最小頻率點以縮小充電過程中的損失，進而達到
縮短充電時間之目的。經由實驗驗證後，本文所提出之充電策略在鋰
離子電池健康度分別為88.14%以及77.26%時，可分別改善0.26%以
及1.85%，與標準型定電流-定電壓充電法相比，充電時間在健康度分
別為88.14%、77.26%以及69.9%情況下，可分別縮短9.14%、18.44%、
8.15%。

In the use of lithium-ion batteries, battery aging has always been a
criticized shortcoming, and the most influential one of battery aging is the
charging technology. In the charging-related research which avoids the
aging of lithium-ion batteries, most of them are to make trade-offs among
charging time, current level, charging capacity, battery temperature rise,
and cycle life, to achieve the purpose of reduced aging effect. In this regard,
this thesis proposes a charging strategy of constant current and C sine wave
voltage. By adding a discharge interval during the charging process, the
purpose of restoring the state-of-health (SOH) of the lithium-ion battery is
achieved, and at the same time, by finding the minimum frequency point
of the AC impedance of the lithium-ion battery, the charging time can be
reduced. After the experimental verification, the charging strategy
proposed in this thesis can improve the lithium-ion battery’s SOH by
0.26% and 1.85% when the SOH of the lithium-ion battery is 88.14% and
77.26%, respectively. Compared with the standard constant currentconstant
voltage charging method, when the SOH is 88.14%, 77.26%, and
69.9%, the charging time can be shortened by 9.14%, 18.44%, and 8.15%
respectively.
