Taking Second-life Batteries from Exhausted to Empowered using Experiments, Data Analysis, and Health Estimation

arXiv:2402.18859v1 Announce Type: new
Abstract: The reuse of retired electric vehicle (EV) batteries in electric grid energy storage emerges as a promising strategy to address environmental concerns and boost economic value. This study concentrates on devising health monitoring algorithms for retired batteries (BMS$_2$) deployed in grid storage applications. Over 15 months of testing, we compile, analyze, and publicly share a dataset of second-life (SL) batteries, implementing a cycling protocol simulating grid energy storage load profiles within a 3 V-4 V …
