When a battery reaches a point where it can no longer be used in an electric vehicle, it still retains 75-80% of its potential capacity for another use. CCSE is participating in ongoing research studies on the second use of these electric vehicle batteries!
In partnership with San Diego Gas & Electric ( SDG&E) and AeroVironment, CCSE is identifying applications where electric vehicle batteries can be used in stationary applications as well as identifying methods for developing the value chain propositions for these second life applications.
The funding for this research comes from the California Energy Commission Transportation Research Division and is administered through the University of California at Davis Plug-In Hybrid and Electric Vehicle Center. The U.S. government, through the National Renewable Energy Laboratory ( NREL), is following up this study with a comprehensive study on the economic consequences of the applications. The follow-up study also examines how the batteries might be better designed or manufactured to maximize their potential for second-life uses.
As part of these research studies, CCSE is creating a two year field demonstration and development analyses of the secondary application at the University of California, San Diego (UCSD).
