2014 Mercedes B-Class ED battery much bigger than previously stated

There was something unexpected hiding in the new configurator for the 2014 Mercedes-Benz B-Class Electric Drive: a $600 "Temporary range extender." Since we've never heard of such a thing, we had to click through for more. The official explanation runs like this: A suite of options to further increase your driving range includes added insulation of the doors and roof for to increase climate-control efficiency, along with an electrically heated windshield and a range-extending charge function. By pressing a button on the console prior to charging, the maximum charge level for battery will increased for the next charge cycle. The higher-capacity charge can provide up to 17 additional miles of range. The passive features that increase range should be standard in all models, we think. But we were more curious about the battery charge situation. How do you increase a maximum? And is it a good idea to do so? The configurator includes this disclaimer, after all: Range extender should only be used on a limited basis, and could shorten battery life if used excessively. How much is excessive? We investigate below. The B-Class ED has, according to the specs, a 28-kWh battery. First, let's understand what this "temporary range extender" is all about. The B-Class ED has, according to the specs, a 28-kWh battery. But Terry Wei, from the Mercedes-Benz USA product and technology communications department, confirmed to AutoblogGreen that the B-Class ED is actually hiding a 36-kWh battery, but the automaker is calling it a 28-kWh battery because that's how much energy capacity is used in day-to-day use. Most automakers publicly claim the actual capacity and then admit they use a percentage of it. The Chevy Volt, for example, has a 16.5-kWh battery pack, but a "full charge" only fills up around 65 percent of that. In the B-Class ED, the 28 kWh of useable energy provides an EPA-certified 87 miles of range. But, since there are eight kWh of reserve, the temporary range extender (we think of it as a software update accessed by a button) can access some of that and offer the aforementioned 17 miles. Now that we know what we're dealing with, this reminds us of an evolved version of the "remote wireless charging" feature that was touted in the Reva EV. Wei said that the reason the feature is optional is because Mercedes doesn't think most people will need it. Eighty-seven miles is plenty for your average EV driver, but when you want to have 100+ in the tank, you can.

Lexus NX, BMW i3 to get Super Bowl commercials

At this point last year, we'd been getting news on automotive-focused Super Bowl commercials for more than two months. The teasers hadn't come out yet, but manufacturers lined up for the super-expensive spots were making their intentions known. This year? Almost nada, until this week. BMW has said it will air a 60-second spot promoting the i3 during the first quarter of the game, the Munich firm returning to The Big Game after a four-year absence. BMW says, "Big ideas like the BMW i3 take a little getting used to, and the creative idea surrounding our spot will play on this analogy." We say that pitching a tiny range-extended hatchback during the beer-iest American sports orgy of the year should make for some neat commentary afterward. Lexus is putting its new NX crossover in the second Super Bowl commercial it's ever aired, eschewing the glitter of celebrities and glamor for a straight-shooting spot and the tagline, "Be seen, be heard, make some noise." Joining those two are Kia, Mercedes-Benz, Nissan and Toyota. The six confirmed carmakers are down from eleven last year, when car spots made up a quarter of the total ad time. The price to do business for 30 seconds this year: reportedly around $4.5 million, up a stacks from last year's $4 million. You can watch the Lexus commercial in the video above, and beneath that, the BMW press release below has a bit more information on its effort. BMW to Advertise All-Electric BMW i3 during Super Bowl XLIX. The all-electric BMW i3 is featured in a 60-second spot during Super Bowl XLIX on Sunday, February 1, 2015. Woodcliff Lake, NJ – January 15, 2015... Today, BMW announced plans to feature the all-electric BMW i3 in a 60-second spot during Super Bowl XLIX on Sunday, February 1, 2015. After a 4-year hiatus, BMW will be returning to the big game with a commercial during the first quarter. "As one in three Americans will tune in to watch the Super Bowl, we are thrilled to use this platform to educate viewers on the importance of electric mobility," said Trudy Hardy, Vice President of Marketing, BMW of North America. "Big ideas like the BMW i3 take a little getting used to, and the creative idea surrounding our spot will play on this analogy." BMW i is BMW's forward-looking and sustainable brand dedicated to solving many of the mobility challenges faced by the world's most densely populated cities. The BMW i3 is the first of the BMW i vehicles constructed from the ground up primarily of carbon fiber.

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.
