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.

Recharge Wrap-up: Houston's bus revival, autonomous trucks on the Autobahn

A documentary shows how Houston, Texas significantly improved its outdated bus system. Called High Frequency: Why Houston is Back on the Bus, the short film describes how the city reimagined its bus system to become more efficient, more useful and more popular. Despite some opposition, the change has proven to be effective, with bus ridership up eight percent in three months, and light rail ridership up due to complementary bus routes. See the video above, and read more at CityLab. Automakers sent autonomous semi trucks on the German Autobahn as part of the European Truck Platooning Challenge of 2016. Mercedes-Benz, Volvo and Scania, among other groups, sent platoons of trucks between Stuttgart, Germany, and Rotterdam, Holland. In Mercedes's platoon of three trucks, the lead truck was fitted with lasers and other sensors to guide the convoy down the road. The two following trucks relied on vehicle-to-vehicle communication to trail 50 feet behind the lead, making room for cars to come between them and closing the gaps when able. The close following distance provides fuel economy gains of up to 10 percent in the rearward trucks on account of the reduction in drag. Read more at Hybrid Cars. Renault has reduced NOx emissions in its Euro 6b diesel vehicles in real world driving conditions. By improving its exhaust gas recirculation systems and NOx traps, nitrogen oxide emissions are cut in half on average, under certain driving conditions. The improvements will be included in vehicles leaving the factory beginning in July of 2016. Beginning in October, owners of Renault Euro 6b diesels can have the modifications added to their cars for free. Read more from Renault. Tata Technologies is creating an innovation lab in California to partner with EV technology companies. Having a tech center in California allows Tata to work on technologies that will largely be deployed in the company's main market of Asia. "Today, we are partnering with companies and startups who have aspirations to sell in China, but a lot of what they do is in California," says Samir Yajnik of Tata Technologies.

RideCell provides technology for services such as carsharing, ridesharing and other transit services. "The convergence of transportation trends in cities is of key importance to BMW," says Ulrich Quay, head of BMW i Ventures.

The BMW 8 Series leads this month's list of discounts

Whether you prefer the sleek looks of a sport coupe, the wind-in-your-hair exhilaration of a convertible or the flexible practicality of a four-door sedan, BMW has an 8 Series to suit your fancy. And if you're in the market right now, you may find that your local BMW dealership is willing to take $18,124 off the sticker price. That figure comes courtesy of TrueCar, and it reflects the discount buyers are getting off the 8 Series' average $122,395 retail price. Most of the 8 Series models in American showrooms today are 2019 models, and that's the model year to which the discount above applies. This represents the largest discount on a new car in America this month, based on the dollar amount off the car's sticker price, and the third largest discount by percentage. And it means the average transaction price for a 2019 BMW 8 Series is hovering at $104,271. 2020 BMW 840i Gran Coupe View 38 Photos BMW offers two distinct versions of the 8 Series, the 335-horsepower 840i with rear- or all-wheel drive, and the 523-horsepower 850i, which comes standard with BMW's xDrive all-wheel-drive system. If you want to step even further up the performance ladder, there's the M8, but that 600-horsepower monster is getting a much smaller $6,150 discount. If you're not into BMWs, the 2019 Mercedes-AMG GT boasts the second largest monetary discount this month, with buyers averaging $16,713 off the Benz's $176,035 sticker price. Another Mercedes, the S-Class, is next with a $11,452 discount. After that comes a pair of Maserati sedans, the Quattroporte and Ghibli, each with discounts of around $11,000. Since the Ghibli's base price is so much lower than that of its larger sibling, that represents a much larger 13.5% cut from its average retail price of $81,384 for an out-the-door cost of $70,373.
