From smartgridnews.com: Unlike standard car batteries, lithium-ion batteries used to power EVs have a lot of life left in them after they’re retired from service in a vehicle. Automation technology group ABB, Nissan North America, 4R Energy and Sumitomo Corporation of America have teamed up to evaluate and test the all-electric Nissan Leaf battery for residential and commercial use as energy storage systems.
Lithium-ion batteries have up to 70% of their capacity remaining after 10 years of service as a car battery. The partners plan to create a Leaf battery storage prototype capable of providing at least 50 kilowatt hours of power, the amount needed to keep the lights on in 15 average homes for two hours.
