Second Use of PEV Batteries: A Massive Storage Resource for Revolutionizing the Grid

Research output: NRELPoster


The market penetration of plug-in electric vehicles (PEVs) and deployment of grid-connected energy storage systems are both presently impeded by the high cost of batteries. Battery second use (B2U) strategies-in which a single battery first serves an automotive application, then is redeployed into a secondary market-could help address both issues by reducing battery costs to the primary repurposed PEV batteries to serve grid applications for energy storage. The authors view this as of significant importance, as our expectation is that such batteries will be both cheap and plentiful. Understanding the dynamics of B2U will be important for customers and utilities in need of storage to understand when and where such batteries will be applicable. It will also be important for suppliers of other energy storage technologies, as repurposed PEV batteries could pose a significant threat to their business model.
