New partnership will evaluate storage systems and back-up power sources using lithium-ion packs from EVs.

Nissan North America, ABB, 4R Energy and Sumitomo Corporation of America have formed a partnership to evaluate whether used electric car batteries could provide residential and commercial energy storage solutions and back-up power sources, making electric vehicles even more sustainable. Their aim is to develop a prototype to effectively reuse lithium-ion batteries taken from the Nissan LEAF.

As electric vehicle batteries have up to 70% capacity remaining after 10 years of use, they can be used beyond the lifetime of the vehicle for other applications. The companies are going to test their use in smart-grid energy management systems and battery energy storage. They plan to develop a LEAF battery storage prototype with a capacity of at least 50 kilowatt hours (kWh), enough to supply 15 average homes with electricity for two hours.
