Reprocessing of Retired EV batteries for Secondary Use: Pulse Test method - Various Challenges and Observations

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution › peer-review

Abstract

It is known that the pulse test on a battery for finding its internal resistance enables fast and accurate battery state-of-health (SoH) determination. This paper details the pulse testing methodology that is deployed as a part of the project for the rapid SoH assessment of the retired Electric Vehicle (EV) batteries so that their sorting and grouping can be done for second-life applications. Various preliminary challenges faced such as noise in the measurements, dissimilarity between different test system outcomes, the effect of temperature on the internal resistance, and others are discussed.
