Summary:

Ford and Microsoft’s move to use Hohm to minimize energy costs for electric vehicle drivers and limit strain on the grid represents a big step toward a “smart charging” ecosystem. But they say tools like Hohm need to go much, much bigger.

Ford and Microsoft’s announcement on Wednesday that they’ll use Microsoft’s Hohm tool to minimize energy costs for drivers of Ford’s electric vehicles — and help limit strain on the power grid for utilities — represents a big step in the development of a “smart charging” ecosystem. But Microsoft and Ford both say Hohm, and other tools like it, need to — and will eventually — offer much more than this initial step.

Nancy Gioia, Ford’s director of global electrification, told us in an interview that the automaker is encouraging the ecosystem that will help bridge the gap between utilities, consumers and vehicles. Gioia called for other car companies to “jump on through the Hohm interface as well,” or use a similar system.

Gioia emphasized some key reasons why Ford decided to go with Hohm. In addition to Ford and Microsoft’s longstanding alliance on Sync, she said Ford liked the open architecture, and the potential for third parties to develop phone apps on the platform. As she explained to us last year, Ford has been working to make its plug-in vehicles “as accepting as possible” when it comes to interfacing with utilities, charging infrastructure developers and energy management software providers.

Thousands of companies — many of them startups — are working on hardware and software for charging plug-in vehicles, Gioia said at the time, adding “We have not come even close to a funnel.” With an open architecture, the idea with Hohm is to keep the doors open for awhile longer.

Gioia also commented on Wednesday that Hohm offers not only a way to help early adopters manage their battery charging, but also to help pave the way for the general adoption of electric vehicles. Gioia said that by using Hohm, consumers can “Find out right away: How’s your house wired?” and figure out what installations or rewiring they might need to accommodate an electric car. When you log into the Hohm site, you can “immediately start to engage your home,” she said.

At the same time, Microsoft is also looking for a wide range of partnerships in this space. The company’s spokesperson Marja Koopmans told us, “It’s critical for a healthy energy ecosystem to collaborate broadly.” And that means working with utilities and municipalities — and also with multiple automakers.

The energy industry is a strategic business area for Microsoft, which has in the past told us it plans to eventually charge utilities for services. Koopmans told us today that while consumers will have ownership of their energy data, Microsoft will aggregate data from Hohm customers and use that to refine and update its algorithm. So more EV drivers means more data, and potentially more value for utilities.

Microsoft is already in talks with other car companies (not surprisingly, Koopmans declined to name specifics). But it’s not clear at this point that other automakers will take the same route as Ford anytime soon, bringing in a very visible partner to facilitate smart charging and serve as a middle man between electric car drivers and utilities.

When we reached out to General Motors and asked whether the company has looked at using Hohm, GM’s Britta Gross pointed to challenges for a one-size-fits-all smart charging system. She commented in an email that the U.S. has 3,000 utilities, and no set standard for them to communicate across the grid. A standardized communication protocol needs to be developed for the 3,000 utilities, she said, before anyone can really “tell when there’s an off-peak energy time.”

In the meantime, Gross said a smartphone app will give buyers of the upcoming Chevy Volt the option to remotely program their vehicle to start charging at a later time, when energy demand (and rates) might be lower. But the company’s app, unveiled in January, doesn’t actually gauge real-time electricity pricing or demand.

Rather, similar to the app concept that Nissan has developed for its upcoming LEAF, GM’s application will allow Volt owners to control certain vehicle functions through GM’s OnStar system and their BlackBerry Storm, Droid or iPhone, for example: schedule battery charge times, view whether or not the vehicle is plugged in, check voltage at a charger, get text notifications of interruption or completion of a battery charge and turn on climate control. According to Gross, GM is currently looking at ways to use OnStar to provide additional options for programming when the battery will start drawing juice from the grid.

Ford CEO Alan Mulally said Wednesday that an electric vehicle could double a typical home’s energy consumption. Put another way, Koopmans said when you buy an electric vehicle, it “becomes the single largest consumer of energy in the home.” So in areas where plug-in cars will roll out in significant numbers, connecting with vehicles will be all but required for a player to be relevant in the world of home energy management.

Koopmans declined to say how much data Microsoft expects to collect from EV drivers, or how large a portion of the total data pool for Hohm in coming years is likely to stem from today’s deal with Ford. “That will grow over time,” she said. “We will learn how quickly we can move on this.”

  1. “the U.S. has 3,000 utilities, and no set standard for them to communicate across the grid” – a pretty good indicator of just how technologically-backwards so much of our nation has become.

    Just as there once was a time when we set the pace for advancing education [OK, it's been a century] we once set the pace for telecommunications, logistics and traffic management. That was a half-century ago.

    The appropriate definition of “corrupt” should include reactionary ideology designed to prevent any positive change.

  6. Thanks, Josie, for the details on one perspective on connecting consumers, utilities and EVs. The use of EVs in particular may actually help to resolve a problem being reported by the utilites regarding their difficulty in managing variations in the grid because of the intermittant input from some of the renewable energy providers. The EVs as both a storage device and a peak load resource might help to moderate the variations the utilities are struggling with.
