Characterizing Aging of Lithium-ion Batteries during Long-term Test Campaigns for Transport Applications

Long-term test campaigns are necessary to understand the aging behavior of lithium-ion batteries in transport applications. During them, a characterization procedure is used to track aging giving both researchers and engineers valuable information. However, no consensus has been found on the procedure to be used. In fact, it is subject to the study under consideration and above all, to time and equipment constraints. Regarding the literature, this work has analyzed and compared non-invasive procedures from past aging test campaigns. Several aspects including duration, data relevance or impact on aging have been discussed. This review aims at helping the reader to choose the most appropriate procedure in line with its application.
