This study addresses the reuse of lithium batteries from electric vehicles in stationary energy storage applications, focusing on extending their lifecycle and efficient usage. These batteries, crucial in various applications, face challenges of capacity degradation, raising questions about their post-lifecycle repurposing. Utilizing electrical models based on Thevenin’s equivalent circuits, the study examines the electrical characteristics of the batteries, focusing on State of Health (SOH) and State of Charge (SOC). It was discovered that within a SOC range of 30% to 90%, the Open Circuit Voltage (VOC) curve by SOC is not influenced by SOH, allowing the use of a standard equation to simulate cells of identical models in different Nissan Leafs. Analysis in five vehicles indicated a correlation of up to 92% between series resistance and remaining capacity and an accuracy of up to 73% when estimated from slow dynamics capacitance. The study revealed high precision of the parametrization method, with a maximum error of only 3.6% in pulsed discharges, particularly effective in the linear range of 30% to 90% of SOC. Despite challenges such as battery balancing and prolonged charging times, the method proved efficient in characterizing the batteries, with minor errors in transient periods and in estimating the VOC curve by SOC. This work not only confirms the viability of reusing lithium batteries in second-life applications but also paves the way for future research into different models and compositions of batteries, significantly contributing to the advancement of battery technology and promoting a circular economy in the energy sector.
