WMG researchers convert used EV batteries into small off-grid ESS units

Green Car Congress

Researchers at WMG, University of Warwick, have repurposed end-of-life electric vehicle batteries as small energy storage systems (ESS) for off-grid locations in developing countries or isolated communities. When an electric vehicle’s battery reaches the end of its useful life it is by no means massively depleted.
