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.

Brabus boosts big Benz plug-in hybrid

With vehicles like the BMW i8 and Porsche 918 Spyder, the Germans have demonstrated as well as anyone that "performance" and "hybrid" can go in the same sentence. And now Brabus is plugging in to the performance hybrid station as well. Though nowhere near as extreme as the aforementioned PHEV sports cars, the Brabus PowerXtra B50 Hybrid performance kit kicks the Mercedes S550 Plug-In Hybrid up a notch. The electric side of the powertrain remains untouched, but the internal combustion engine has been boosted by 51 horsepower and 52 pound-feet of torque. That gives the 3.0-liter turbocharged V6 a total of 385 hp and 405 lb-ft, which is nothing to cough at – but with the electric boost kicking in, the vehicle now packs a combined output of 493 hp and 656 lb-ft. That slots its twist figure in between that of the S600 and S63 AMG. As a result, the big Brabus hybrid will now reach 62 miles per hour from a standstill in just 4.9 seconds (down from 5.2) – almost as quick as the 12-cylinder model but with half the pistons – though the top speed remains pegged at 155 mph. Naturally, Brabus didn't stop there, giving the sedan a new exhaust, aero kit, rolling stock and interior, all catered to the customer's specifications. BRABUS PowerXtra B50 Hybrid with 368 kW / 500 hp (493 bhp) and 890 Nm of torque The eco-friendly performance upgrade for the new Mercedes S 500 PLUG-IN HYBRID For more than 35 years, BRABUS has been the synonym for powerful high-performance automobiles and exclusive refinement at the highest level of perfection. One philosophy has always been paramount in all these years: combining top performance with exemplary eco-friendliness, immaculate durability and perfect everyday practicality. With the new BRABUS PowerXtra B50 Hybrid performance kit for the new Mercedes S 500 PLUG-IN HYBRID, the engine specialists of the world's largest independent tuner once more demonstrate their unrivalled know-how. The power increase of the V6 engine by 38 kW / 52 hp (51 bhp) and the boost in torque by 70 Nm (52 lb-ft) bumps the system output of the hybrid sedan to 368 kW / 500 hp (493 bhp) and system torque to 890 Nm (656 lb-ft). As a result, the luxury liner sprints from rest to 100 km/h (62 mph) in just 4.9 seconds, and impresses in daily driving with even further enhanced superiority. Due to the hybrid system, the top speed remains electronically limited to 250 km/h (155 mph).

Mercedes-Benz says no to price premium on S550 PHEV

The good news? Mercedes-Benz won't be charging any extra for the plug-in hybrid version of the S550 sedan compared to the gas-powered version. The bad news? The gas-powered version is really expensive. The S550 Plug-in Hybrid's pricing will start at a tidy $95,325, the same as the conventional S550, according to Cars Direct. For that price, buyers get a car that delivers 436 horsepower and 479 pound-feet of torque while having the ability to go as far as 18 miles on electric power alone, assuming that the driver in question isn't trying to use all 436 horses. But just in case he or she is, the car can also go from 0 to 60 miles per hour in about five seconds. There's been no word on a fuel-economy rating from the US Environmental Protection Agency (EPA) but the sedan gets 84 miles per gallon on the more lenient European driving cycle. It's unlikely to anywhere close to that stateside, but some folks still might feel they got their money's worth (ha ha) by adding a plug. The S550 Plug-in Hybrid goes on sale in California later this month. The model was first unveiled at the Frankfurt Auto Show in 2013 and shown off at the Los Angeles Auto Show late last year.
