Electric car batteries can do more than power electric cars. They can send current to homes and buildings, or send it back to the grid when demand is high. Some experts even believe EV batteries might one day boost the prominence of renewables by storing the energy from wind and solar farms.
The idea of so-called “vehicle-to-grid” schemes inevitably stirs debate among engineers. But make no mistake: The concept has a huge following. Googling the term “vehicle-to-grid” yields an astounding 526 million hits. That’s one reason electric utilities, auto manufacturers, and university researchers are all studying the concept.
We collected photos and diagrams from ongoing vehicle-to-grid programs. From pure EVs to plug-in hybrids to wild-looking concept cars, we offer a peek at some of the vehicles that could one day power your home.

Willett Kempton of the University of Delaware has been a driving force behind the idea of vehicle-to-grid (V2G) technology. In 2013, Delaware teamed with NRG Energy to launch the world’s first revenue-generating V2G project. Here, Kempton is shown with a Honda Accord Plug-In Hybrid that’s being used as part of a demonstration project by the university.
