GE's joint showcase with Nissan at the SAE 2012 World Congress in Detroit displayed technology that can reverse the flow from your electric car's batteries to power your home in a blackout.
The technology to support a home that is fully integrated into the smart grid -- from the ecomagination-certified WattStation home EV charger, to the Nucleus Home Energy Manager to fully connected appliances -- isn't just in a trade show booth. It's ready and working today.
Using an electric cars battery for 'vehicle to grid' (V2G) power may make EV owners an income of $4000 a year. That is a sum far greater than the $225 that Nissan, for instance, thinks will be the average annual cost of the electricity needed to power one of its Leafs.
