Duke Energy and Tokyo-based ITOCHU Corp. signed an agreement to collaborate on advanced energy technologies, starting with the evaluation and testing of second-life applications for electric vehicle batteries.
According to some auto industry estimates, electric vehicle (EV) batteries that can no longer charge to approximately 80% of their original capacity may be candidates for replacement. Duke Energy and ITOCHU believe batteries that become unsuitable for use in EVs could live on in other applications. Reuse possibilities for these batteries include providing a supplemental home energy supply, storing renewable power and providing a fast-charging power source for EVs.
