2nd lives for EV batteries could cut prices: Automakers, partners test uses for retired lithium ion power packs

摘要

Lithium ion battery packs that power some electrified vehicles could end up feeding juice H into the electrical grid - a development that could cut EV ownership costs. Although the electrified vehicle market is still in its infancy, automakers and power companies are experimenting with second-life uses for the batteries once they're retired from the road. Battery experts say the shelf life of a lithium ion battery in an EV is around 10 years, and automakers such as General Motors and Nissan are pondering what to do with still-useful units.
