Ford’s Director of Sustainability, John Vierra explained on Michigan Radio the advantage of the software saying, “The electric companies are saying, okay, the cost of electricity is cheaper at these times, then (they) communicate through the vehicle back to the house, and then the house actually turns on the electricity when the electric rates are the cheapest.”
Vierra also noted that electric companies will also get useful information on their end. “You can imagine the future when we have a lot of these electric vehicles in a concentrated area, the electric companies are going to want to know that so they can ensure a supply of electricity to those regions.”
Hohm will enable smart charging for Ford’s electric vehicles. Ford CEO Alan Mulally announced at the New York International Auto Show that he automaker and Microsoft are “automating and optimizing the process of when and where and how to charge your electric vehicle.” He also noted that Hohm will “help utilities better understand” the electricity drain plug-in vehicles will cause.
Microsoft’s Troy Batterberry added, Without Hohm, there would be a proverbial traffic jam on the grid.” Battery charging will be managed based on energy pricing and a consumer’s schedule.
Hohm will also provide drivers with remote and automated control.
Ford also announced it’s working on an iPhone app that provides remote monitoring of a battery’s charge status and charging controls.
