V2H Power Technology from Toyota
|   Friday, June 15, 2012
The Vehicle-to-Home power system was tested by Toyota Motor Corporation with the help of the Prius Plug-in hybrid car. The technology has turned the Prius hybrid into an emergency generator. This V2H technology will begin its test project with ten selected smart homes in Toyota City.

For many years, charging through an electric car has been a hot issue and mostly the concept discussed was how the electric car will charge from a domestic charging source.
Now, Toyota has turned the discussion around and is going to experiment with how a domestic house unit can source its power from an electric car.

Toyota's V2H (Vehicle-to-Home) system of charging will offer a mutual charging possibility between a domestic power supply source and the Prius Plug-in. By doing this, Toyota is taking one step closer to becoming a smart grid itself. Toyota announced this project about five days ago. During a power outage or as a supplement source of power supply during peak load periods, the Prius Plug-in can fill in as a generator.

The small lithium-ion battery of the Prius Plug-in may not be enough to supply electricity all the time to a home like a grid does but Toyota feels that it will be enough for selected points during blackouts, much in the same way that the inverter functions. Toyota is also planning that the Plug-in will draw power during the hours that are off-peak and then transfer that stored power in return, back to the house during the peak hours. This will help to reduce the cost of energy. Toyota says that the Prius Plug-in will be able to supply power to an average domestic unit for a maximum of three days.

A hundred volt inverter aboard the Prius will convert the power stored into an alternate current which will be suitable for domestic use. With this strategy, the generated electricity will be low-carbon from domestic solar generators. Even inexpensive late-night power can be stored in a car's drive battery and may be used later to give power to the home during peak hours.
