An EV solution to home energy

When an EV battery ages and to lose range, it still has of life left in it. Rather sending it straight to the recycler, you hook it up with a bunch of used EV batteries in a stationary system. Sounds like a idea, right?


The question is such a system is commercially and Sumimoto Corporation is about to out.

Sumimoto has just an energy storage system from used EV batteries, it claims to be the first large-scale of its kind in the world. The system is to begin operating later month.

Well, don’t get too excited all at The facility is not exactly a commercial at least not yet. It is a prototype selected by the Japan Ministry of the as a model project under the of “verification of the battery storage to promote renewable energy”.

developed the facility in cooperation Nissan, starting with the of a joint venture company 4R Energy Corporation back in

Located on Yume-shima Island, the 600 kw/400kwh system consists of 16 EV batteries. It will charge up the nearby Hikari-no-mori solar

Over the next three the system will be studied for its to smooth out fluctuations in energy from the solar farm, an eye toward developing a larger, viable system.

Ford Company already has a similar under its belt. Back in installed a 500 kw solar array as of a green makeover for its Michigan Plant, and they hooked it up to a EV battery storage system as as new energy storage facilities.

Like the Sumimoto system, used battery endeavour is a facility. If it proves successful, a lot of new EVs hitting the road a few years now could be manufactured with the of power cannibalized from old EV

So, is used EV battery energy commercially viable?

Maybe. in 2003, Sandia National studied the issue and determined there could be a future to cost-effectiveness.

More recently, in Oak Ridge National Laboratory a dim view of the matter overall, but that certain applications for a EV battery energy storage could be profitable, one best-case being the aggregation of multiple in a community energy storage

A business case begins to when applications with a low factor, like voltage (only a few hours over the operating life of the system), are with applications that the utilisation factor of the system

of use energy management (peak is the most promising application for energy storage (CES). of use energy management makes sense where communities energy storage systems for peak shaving and indirect to the distribution and transmission system as upgrade deferral, and reserve capacity, may be realised.

The peak shaving angle be a winner for business, if it could be into an energy storage that enables large utility customers to avoid demand charges .

BMW, for isn’t letting Sumimoto on its laurels. Last fall BMW announced a partnership with the Vattenfall to develop secondary for EV batteries .

GM is also in on the action, a used EV battery microgid system developed with the company ABB.
