“…The findings from the first industry study have revealed that the primary challenge to be overcome regarding SLBs is ensuring their economic viability. This challenge is primarily attributed to the significant variability among battery types from different manufacturers, which presents obstacles in achieving a uniform repurposing procedure for a second-life Energies 2024, 17, 988 5 of 17 application [6,[17][18][19]. Through the evaluation of all interviews, the following five economic challenges were determined as the most important to overcome: Thus, it becomes evident that rentability is the main barrier for the second-life battery.…”

As the production of battery cells experiences exponential growth and electric vehicle fleets continue to expand, an escalating number of traction batteries are nearing the conclusion of their operational life for mobility purposes, both presently and in the foreseeable future. Concurrently, the heightened interest in sustainable energy storage solutions has spurred investigations into potential second-life applications for aging traction batteries. Nonetheless, the predominant practice remains the removal of these batteries from electric vehicles, signifying the end of their life cycle, and their subsequent incorporation into recycling processes, with limited consideration for life-extending measures. This study seeks to elucidate the reasons behind the deprioritization of battery repurposing strategies. Therefore, the research team conducted two industry studies with over 20 battery experts from Europe, revealing concerns about the economic viability of repurposing batteries for stationary storage applications. A literature review of studies published since 2016 confirmed the industry’s struggles to address this issue theoretically. In conclusion, a research question was formulated, and a solution approach was delineated to assess the economic prospects of aged traction batteries within the industry’s landscape in the future. This solution approach encompasses pertinent market analysis, the identification of representative second-life applications, as well as the formulation of a methodology for evaluating the residual value of these batteries.

“…To ensure the performance requirements of lithium-ion batteries, IEEE standard 1188.1996 clearly states that when the battery SOH is less than 80%, it indicates that the end of life has been reached and the battery needs to be replaced [32][33][34].…”

Lithium-ion power batteries have been widely used in transportation due to their advantages of long life, high specific power, and energy. However, the safety problems caused by the inaccurate estimation and prediction of battery health state have attracted wide attention in academic circles. In this paper, the degradation mechanism and main definitions of state of health (SOH) were described by summarizing domestic and foreign literatures. The estimation and prediction methods of lithium-ion power battery SOH were discussed from three aspects: model-based methods, data-driven methods, and fusion technology methods. This review summarizes the advantages and disadvantages of the current mainstream SOH estimation and prediction methods. This paper believes that more innovative feature parameter extraction methods, multi-algorithm coupling, combined with cloud platform and other technologies will be the development trend of SOH estimation and prediction in the future, which provides a reference for health state estimation and prediction of lithium-ion power battery.

“…The repurposing process requires disassembling the batteries to the cell level, testing the cells' SOH, and reassembling them to fit the new application. Another step is the control system; both hardware and software must be suited for the new application [7] [16] [17]. It is important to identify areas complementary to the demands of automotive applications, with lower demands on battery performance.…”

The purpose of the study is to explore an economically viable second life applications for electric vehicles (EV) batteries. There is a common consensus in the automotive industry that the reuse of retired EV batteries—often referred as a second life of a battery—can provide greater economic and sustainability benefits. Although literature acknowledged potential business opportunities with batteries’ second life, there are still a lot of uncertainties, making success difficult to realize. In particular, identification of a profitable second life application with a right business model in the battery value chain has become a key success factor. Therefore, a case study, with a mixed research approach, considering both qualitative and quantitative methods, has been conducted in a company that is one of the leading manufacturers in the heavy-duty industrial vehicle industry, which currently is developing their electric vehicle machines with a li-ion battery pack. The study generated and analyzed several different second life concepts to find the most economically viable second life applications. The analysis concluded three second life business concepts in the initial phase. In the later phases, individual business model canvases and different reverse logistics processes were created, mapped, compared, and validated through quantitative analysis. The analysis show that out of three concepts remanufacturing application proved to be the most applicable one for the case company, within a range of 15 years’ time. The paper contributes to the theory of circular business models in the context of EV batteries.
