ABB alliance plans to connect electric car lithium ion batteries to the power grid

Nissan, ABB to evaluate lithium ion batteries re-use. Lithium ion batteries of electric vehicles to be tested for energy storage. Batteries are the most expensive component of an electric car, costing several thousand dollars depending on the size.

Nissan and electric power company ABB yesterday announced a partnership to test the technical and commercial feasibility of repurposing used EV batteries for energy storage on the grid and in homes. ABB will work with a joint venture called 4R Energy (for reuse, refabricate, resell, recycle) created by Nissan North America and industrial conglomerate Suminoto to research secondary uses of EV batteries.

The team plans to develop a LEAF battery storage prototype with a capacity of at least 50 kWh. The purpose is to evaluate and test the residential and commercial applications of energy storage systems or back-up power sources using lithium-ion battery packs reclaimed from electric cars after use.

Electric car batteries have up to 70 percent capacity remaining after 10 years of use in an automotive application. This longevity allows them to be used beyond the lifetime of the vehicle for applications such as a smart-grid community energy management system or battery energy storage.
