2014 Honda Accord PHEV
Honda announced that, together with University of Delaware and NRG Energy, it will experimentally verify vehicle-to-grid (V2G) usefulness:
"Honda has joined a demonstration project for experimental vehicle-to-grid (V2G) technology aimed at providing a potentially valuable energy storage resource to the nation's electrical grid while providing for more cost-effective ownership of plug-in electric vehicles."
The University of Delaware and NRG Energy recently launched the joint venture eV2g that should spearhead V2G.
What's interesting is that Honda will not provide Fit EVs to the project, just Accord PHEVs.
Now we can answer Jay's burning question on low sales of Accord PHEV "Why do they bring them to the US at all?" Because Honda needs a V2G demonstrator.
The V2G Accord PHEV is equipped with a bi-directional on-board charger and it will go to the University's Science, Technology and Advanced Research (STAR) Campus.
"With an additional communication device, the vehicle receives signals from a grid operator via a charging station, and controls charge and discharge in accordance with the signals. When electric power is requested by the grid, the vehicle will discharge power from its battery. When the grid power supply exceeds demand, the vehicle proactively charges its battery."
