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.

Child cobalt miners: Automakers pledge ethical minerals sourcing for EVs

BERLIN - Leading carmakers including Volkswagen and Toyota pledged on Wednesday to uphold ethical and socially responsible standards in their purchases of minerals for an expected boom in electric vehicle production. Demand for minerals such as cobalt, graphite and lithium is forecast to soar in the coming years as governments crack down on vehicle pollution and carmakers step up their investments in electric models. To cover its plans for more than 80 new models by 2025, Volkswagen alone is looking for partners in China, Europe and North America to provide battery cells and related technology worth more than 50 billion euros ($59 billion). Talks with major cobalt producers, including Glencore, at VW's Wolfsburg headquarters last week ended without a deal. More than half of the world's cobalt comes from the Democratic Republic of Congo, a country racked by political instability and legal opacity, and where child labor is used in mines. On Wednesday, a group of 10 leading passenger-car and truck manufacturers announced an initiative to jointly identify and address ethical, environmental, human and labor rights issues in raw materials sourcing. The partnership dubbed "Drive Sustainability" consists of VW, Toyota Motor Europe, Ford, Daimler, BMW, Honda, Jaguar Land Rover, Volvo Cars and truckmakers Scania and Volvo. The alliance "will assess the risks posed by the top raw materials (such as mica, cobalt, rubber and leather) in the automotive sector," said Stefan Crets of the CSR Europe business network. "This will allow Drive Sustainability to identify the most impactful activities to pursue" to address issues within the supply chain.Reporting by Andreas Cremer.Related Video: Image Credit: Michael Robinson Chavez/The Washington Post via Getty Images Green BMW Ford Honda Jaguar Land Rover Mercedes-Benz Automakers Toyota Volkswagen Volvo Green Automakers Green Culture Electric Scania ethics mining

Aston or Bust? Maybach's fate to be decided next month

2011 Maybach 62 - Click above for high-res image gallery
What will become of Maybach? That question has been rattling around the halls of Daimler headquarters in Stuttgart for some time now. But all questions will be answered, and answered soon: according to reports, the German automaker is currently evaluating prototypes and propositions for its top-end marque, and will make its decision next month.
So, what are the options? On the one hand, Daimler could kill the Maybach brand altogether. It was a notion ill conceived and even more poorly executed, taking an old platform and building a new flagship atop it. In that way, it was sort of like the Chrysler Crossfire, only far more costly to both the buyer and manufacturer. On the other hand, Daimler could opt for the long-time-coming proposition of contracting the production (and possibly much of the development) of a new generation of Maybachs to Aston Martin.
