8 automakers, 15 utilities collaborate on open smart-charging for EVs

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.

Mercedes-Benz B-Class Electric Drive gets official US launch

It's finally time to plug in the first production Mercedes-Benz-branded electric vehicle in the US. The Daimler division, which also sells a few of its battery-electric Smart ForTwo vehicles here in the states, has officially launched sales of the Mercedes-Benz B-Class ED. Even better, the US will be the first market in the world to give the general public access to the new plug-in. As with many other EV debuts, the flyover states will have to wait a bit. Mercedes-Benz is only selling the B-Class ED in 10 coastal states, including California, Oregon, New York, New Jersey, Maryland and Maine, and hasn't said anything about when a broader release might happen. Earlier this month, the US Department of Energy rated the B-Class electric with an 87-mile single-charge range, which is comparable to that of the Nissan Leaf and BMW i3. The other shoe dropped, though, when it was revealed that the model has an 84 miles per gallon equivalent rating, which is about 30 percent less then both of those other EVs. The culprit for the model, which puts out 177 horsepower and has a base price of $41,150, is its heavier curb weight. Check out Autoblog's "First Drive" impressions here.

Mercedes-Maybach previews longer, more lavish S-Class ahead of debut

In some international markets, Mercedes-Benz's new 2021 S-Class will get Level 3 semi-autonomous technology, but chauffeur-driven buyers already enjoy full autonomy. It's for these individuals that Mercedes-Maybach, the firm's extra-luxury division, stretched the sedan's wheelbase and gave it an interior worthy of a private jet. Maybach said it developed its variant of the 2021 S-Class specifically for buyers with a chauffeur. It added seven inches to the sedan's wheelbase, and the additional sheet metal benefits those riding in the back. Standard executive rear seats give passengers a comfortable place to work or rest while they're being driven, and the list of new features added to the sedan include massaging calf rests as well as heating for the neck and shoulders. Although we haven't seen Maybach's S-Class yet, a preview image shows the optional two-tone paint — one of the company's hallmarks — and a chromed Maybach emblem. Up front, it will receive a specific grille with vertical slats instead of the horizontal ones worn by the standard S-Class. An additional serving of chrome-look trim will almost certainly further set the Maybach apart, but it will retain its predecessor's relatively subtle design. Specifications won't be announced until the model's unveiling. Mercedes-Benz confirmed it's phasing out V12s, though the big engine could return for one final round under the hood of the S-Class. Alternatively, Maybach may have chosen to surf the downsizing wave still sweeping across the industry by selecting a 4.0-liter V8. Mercedes-Maybach will introduce the 2021 S-Class online on November 19 at 2 p.m. Stuttgart time, which is 8 a.m. in New York City and 5 a.m. in Los Angeles. Deliveries are scheduled to start during the first half of 2021. When it lands, the sedan will join Maybach's variant of the GLS in showrooms across the United States. Related Video:
