We're going to lead with General Motors here. GM is one of eight automakers working with 15 utilities and the Electric Power Research Institute (EPRI) at developing a "smart" plug-in vehicle charging system. Why did we start with GM? Because it's the first automaker whose press release we read that mentioned the other seven automakers. Points for sharing.

For the record, the collaboration also includes BMW, Toyota, Mercedes-Benz, Honda, Chrysler, Mitsubishi and Ford. The utilities include DTE Energy, Duke Energy, Southern California Edison and Pacific Gas & Electric.

The idea is to develop a so-called "demand charging" system in which an integrated system lets the plug-ins and utilities communicate with each other so that vehicle charging is cut back at peak hours, when energy is most expensive, and ramped up when the rates drop. Such entities say there's a sense of urgency to develop such a system because the number of plug-in vehicles on US roads totals more than 225,000 today and is climbing steadily.

There's a lot of technology involved, obviously, but the goal is to have an open platform that's compatible with virtually any automaker's plug-in vehicle. No timeframe was disclosed for when such a system could go live but you can find a press release from EPRI below.

EPRI, Utilities, Auto Manufacturers to Create an Open Grid Integration Platform for Plug-in Electric Vehicles

PALO ALTO, Calif. (July 29, 2014) – The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and demonstrate an open platform that would integrate plug-in electric vehicles (PEV) with smart grid technologies enabling utilities to support PEV charging regardless of location.

The platform will allow manufacturers to offer a customer-friendly interface through which PEV drivers can more easily participate in utility PEV programs, such as rates for off-peak or nighttime charging. The portal for the system would be a utility's communications system and an electric vehicle's telematics system.

As the electric grid evolves with smarter functionality, electric vehicles can serve as a distributed energy resource to support grid reliability, stability and efficiency. With more than 225,000 plug-in vehicles on U.S. roads -- and their numbers growing -- they are likely to play a significant role in electricity demand side management.

The platform enables integration across multiple communication pathways, such as automated metering infrastructure (AMI), home area networks, building energy management systems, and third party entities that aggregate energy management services for commercial and industrial power customers.

Researchers anticipate that grid operators in the future may call on electric vehicles to contribute to grid reliability by balancing solar and wind generation, mitigating demand charges and providing ancillary services such as frequency regulation and voltage support.

Utilities and regional transmission organizations participating and supporting in the software and hardware development and demonstration include DTE Energy Company, Duke Energy, PJM Interconnection LLC, CenterPoint Energy, Inc., Southern Company, Northeast Utilities, Southern California Edison, Pacific Gas & Electric Company, San Diego Gas & Electric, Commonwealth Edison, TVA, Manitoba Hydro, Austin Energy, Con Edison and CPS Energy.

Auto manufacturers are American Honda Motor Co., BMW Group, Chrysler Group LLC, Ford Motor Company, General Motors Co., Mercedes-Benz Research & Development North America, Inc., Mitsubishi Motors Corporation, and Toyota Motor Engineering & Manufacturing North America, Inc.

"A key aspect of the platform's benefits will be giving customers flexibility and choices," said Dan Bowermaster, EPRI manager of Electric Transportation. "It can help the PEV customer determine the value of using their parked vehicle as a grid resource, and help the industry develop a convenient, user-friendly customer interface. We see this as the foundation for future developments to integrate PEVs with the grid."

Additionally, it could increase service reliability to customers by helping to mitigate the impact of strain on the grid during peak periods and could contribute to curbing greenhouse gas emissions. Utilities might benefit by better managing their loads and avoiding upgrades to infrastructure --savings that can be passed onto utility customers.

Sumitomo Electric will develop the core platform technology on the first phase of the project.

This software platform aligns with the Vehicle Grid Integration (VGI) Roadmap Initiative of the California Public Utilities Commission and the California Independent System Operator, as well as conforming with standards set by IEEE, IEC/ISO, and SAE, and Open ADR Alliance, making it globally applicable.

      It's about time. Access to electricity is effectively a basic human need and the grid in the US is profoundly neglected. Anything and everything that can be done to make electricity transmission and use better and more reliable must be done, yesterday so to speak. So, Tesla/Solar City/Elon are really doing something concrete and positive in the field while all these guys have just started thinking about these issues. It's about time.

      Better work out a demand system for Air Conditioners and electric oven/ranges. I hear those are really catching on and draw more power than most L2 chargers.

        Demand-response for airconditioners is already done in California. Ovens/Ranges .. . . . meh. Can't stop people from making their dinner.

      Excellent. Everyone knows that such a system would be needed eventually but it is nice to see them recognize that now is the time to act. EVs can play a huge part in stabilizing the grid and making it easy to add lots of renewables to the grid.

      Having worked with both the Auto Manufacturers and Utility companies, I'm certain that getting all those businesses to focus on this common topic was no small task. This a huge and important achievements. The trailblazers on this list will be owed a huge debt of gratitude by the millions that buy the electric vehicles of the future. So many people have questioned the value of these activities. I believe an efficient way to power transportation that minimizes environmental impact involves finding ways to reduce the amount of transportation needed at the same time that the remaining needed transportation is made as ecofriendly as possible. By Ecofriendly, I mean the total Eco impact of a mode of transportation. The total carbon emitted and water used in the processes of building, selling, distributing, operating, fueling, reselling and scrapping all modes of transportation. I'm also thinking about the impact in all those cycles of the infrastructure needed to support those. Rails, roads, waterways, terminals and airspace. with the advent of big data tools, the enormous cubes of data and the processing needed to look for the best patterns in the data are available to us. We just need to will to do something about it all. Bravo to the group of companies that are forging open standards to help us all go further down this path.

      Oh joy, Toyota and Chrysler joined so that they could sabotage the effort. It's funny to think how Toyota used to be a green car company, and now it is the one most tied up with the oil companies.

        While both Toyota and Chrysler have a pretty terrible track record on pure EVs, both of them are committed to PHEVs. Meanwhile, while their investments in plug-in vehicles might be on a smaller scale than other automakers, that doesn't mean they haven't been able to put a few key engineers on the task of working on some of these key issues.
