V2G: Transportation Electrons vs. Power Electrons
by Eric Weshoff (GreenTechGrid) Integrating electric vehicles into the smart grid is an enormous and potentially explosive challenge.
Erfan Ibrahim of EPRI has said that if electric vehicles reached a high level of market penetration and were to charge at night or in an unregulated way, it would look and sound like the Fourth of July from all of the utility transformers blowing up. These potential pyrotechnics and much more were covered in an event put on by Agrion LLC to address EV technology and vehicle-to-grid (V2G).
Vehicle-to-grid (V2G) describes an ecosystem in which electric vehicles or plug-in hybrids communicate with the power grid to leverage demand response services by sending electricity into the grid or by staging their charging rate in a process called demand dispatch or smart charging.
…And here’s another good question: What happens to the vehicle manufacturer’s warranty? Since batteries will be warrantied in miles, wouldn’t using the battery for V2G void the warranty?” READ MORE
