Batteries retired from electric vehicles still maintain significant battery capacity. While that capacity may no longer meet the minimum requirements for the initial application, they could provide sufficient capacity for less demanding applications. Repurposing batteries to less-demanding applications not only provides a higher value through the life of the battery, it increases sustainability by postponing recycling as well.
In this line, Cummins has announced a multi-year partnership with the University of California San Diego and its battery validation lab to analyze viable business and technical approaches to effectively reuse and repurpose electric vehicle batteries.
Under the agreement, UC San Diego will perform accelerated testing and real-world application testing, and will develop an outdoor second-life demonstration system comprised of Cummins battery modules. The collaboration will enable the company to acquire valuable data on the aging behaviors of its battery modules, test integration solutions for second-life battery systems, and validate stationary energy storage system performance under grid energy storage applications.
The partnership with UC San Diego represents one of the first lithium-ion battery projects to exclusively study second-life battery capabilities with batteries that were designed for commercial applications.
