Monitoring Considerations of Second-Life Lithium-Ion Batteries inBattery Energy Storage Systems

Abstract:
This paper presents an analytical study of the most important technical aspects that should be considered in the methodologies for monitoring second-life lithium-ion batteries in stationary energy storage systems. The study is based, on one hand, on the specificity of these batteries in terms of changing their response differently in the second-life than in the first to external and operational influences. On the other hand, it is based on the monitoring requirements of storage systems to obtain an improved monitoring system with sufficient accuracy and more efficient performance of batteries in their second-life.
