摘要

現今鋰離子動力電池的高成本是電動車售價高居不下的主要原因之一，為有效降低電動車動力電池的成本，近幾年來，各國紛紛投入汰役電池二次應用的產業與技術研究，延長動力電池使用期限與增加成本效益；本文研究目標為應用於電動車上3-5年後或行駛30萬公里以上之動力鋰電池，這些電池的容量降至原出廠容量的70-80%以下，無法滿足電動車應用的高性能與高安全性的使用需求，但這些動力電池相較於傳統鉛酸電池新品仍具較大的能量密度，將這些汰役電池能經過一連串完整的檢測、分級、分容、重組、與認證等重製翻新程序後，再生電池組可二次應用於儲能系統與備用電源等產業。

One of the main reasons for the prices of electric vehicles (EV) remaining high is the high cost of lithium-ion battery. In order to help reduce the cost of EV batteries so as to increase the market penetration of EV, in recent years, many countries make efforts in technical researches in the reuse of the batteries removed from EVs such as by extending the service life of the batteries. The research reported in this paper targeted the retired battery used by EV for 3~5 years or more than 300 thousand kilometers. The energy storage capacity of these batteries may already drops to only 70-80% which is not sufficient for EV application according the typical high performance and high safety industry requirements. Compared to new lead acid batteries, these retired lithium-ion batteries usually still have higher energy density. These retired lithium-ion EV batteries have the opportunities to be further used for energy storage or backup power systems if they are undertaken through proper testing, classification, sub-capacity, repackage, and certification etc.
