Abstract
Official abstract text for this publication.
A method for reusing a secondary battery by reusing unit cells or battery modules constituting reclaimed assembled batteries (or battery packs) to reconstruct a new assembled battery is disclosed. Assembled batteries are reclaimed, and disassembled into battery modules. The battery modules are selected based on battery characteristics such as an open-circuit voltage (OCV) and the like using an absolute acceptable range and a relative acceptable range, and a new assembled battery is rebuilt. The relative acceptable range is an acceptable range which is set for each assembled battery, and is set to have its center at an average value of a battery characteristic distribution.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for reusing a secondary battery by reconstructing an assembled battery from a plurality of used battery modules or unit cells, the method comprising: a measurement step of measuring battery characteristics of a plurality of used battery modules or unit cells obtained by disassembling a plurality of used assembled batteries; a selection step of selecting reusable battery modules based on the battery characteristics measured in the measurement step;…
