“…There is variation in the internal parameters of cells in LiBs, even for fresh cells. Based on the outcome of the previous study and the measurements on 700 Li-Po cells [66], it was observed that cells belonging to the same manufacturer and batch are not identical in terms of internal parameters, as was illustrated in Figure 4. These inherent variations originate from the manufacturing process of the cells.…”

The surge in electric vehicle adoption has resulted in a significant rise in end-of-life batteries, which are unsuitable for demanding EV applications. Repurposing these batteries for secondary applications presents a promising avenue to tackle environmental and economic challenges associated with their disposal. The second-life battery (SLB) approach emerges as a mechanism to manage this massive amount of retired EV batteries. However, this approach poses significant challenges in determining and monitoring battery degradation and performance. After evaluating different scenarios for reusing or recycling retired EV batteries, this paper examines the main challenges associated with SLBs, including techno-economic aspects, uncertainty from first life, safety, characterization and screening, battery-management systems, and secondary applications. A comprehensive review of current state-of-the-art SLB research and implementations is provided, particularly emphasizing battery characterization and the requisite evaluation processes for SLB eligibility. This paper explores diverse measurement techniques for assessing SLB performance, evaluating them based on accuracy, complexity, and time consumption, which are essential for achieving cost-effective SLB applications. The overarching objective is to thoroughly understand the principal challenges associated with repurposing EV batteries and delineate the research imperatives necessary for their successful implementation and prolonged lifespan.

“…Due to manufacturing complexity, the battery cells commonly have different intrinsic characteristics like self-discharge rates, internal resistance and impedance, and thermal performances leading to different state-of-charges (SoCs) during operation in battery packs. These disparities between the cells become wider especially when the battery ages [1], [2]. This can result in reduced battery capacity, shorter battery lifetime, and in extreme cases, safety hazards leading to battery fires and explosions [3].…”

This work focuses on the so-called split batteries and proposes the T-type cascaded H-bridge circuit, as a suitable candidate for this application. Furthermore, state-of-charge (SoC) balancing between the battery modules is done by a hierarchical algorithm without requiring any ancillary balancing hardware.To minimize the number of switches in the conduction path and to increase efficiency, the conventional hierarchical algorithm is modified for the T-type based cascaded H-bridge. Finally, a simulation in MATLAB Simulink is performed to verify the feasibility of the proposed AC battery and both conventional and modified balancing algorithms.
