Daimler, BMW partnering up on wireless charging

Plug-in vehicle advocates can get all warm and fuzzy about two Germany heavyweight automakers getting together for the sake of wireless charging. That's because Mercedes-Benz parent Daimler and BMW will work together to speed up development of a wireless charging system. While not a ton of details were divulged, we can still rejoice. Daimler says the system will consist of an on-board coil and another coil that can be placed within the garage floor or someplace similarly stationary. The system will charge at 3.6 kilowatts and with 90 percent efficiency. No details were released about the system's price or when it would be available, but Daimler shouldn't wait too long, since other OEMs are already talking about their own wireless charging systems. Daimler obviously has some skin in the game here, since Mercedes-Benz will start sales of its S500 plug-in hybrid in September. That model, which was first shown off last August at the Frankfurt Auto Show, can go as far as 20 miles on electric power alone and will get fuel economy of about 84 miles per gallon equivalent. And it's easy to imagine an i3 or i8 driver getting a kick out of never needing to touch a cord. This spring, reports sprung up that fellow German automaker Volkswagen was preparing a wireless charging option for its electric vehicles as soon as 2017. You can check out Daimler's press release below. Wireless charging of electric drive and plug-in hybrid vehicles: PLUG IN HYBRID - unplugged One of the next steps on the way to perfect electric drive and plug-in hybrid vehicles is wireless charging. Daimler and BMW have now agreed on jointly developing and implementing one common technology. Wireless charging of the battery will make the handling of electric drive and plug-in hybrid vehicles even easier. Mercedes-Benz will commence fleet testing of this "unplugged" technology with the S 500 Plug in HYBRID soon, in order to develop a real S-Class solution in recharging the high voltage battery in terms of comfort and ease of operating in the near future. The system consists of two components: a secondary coil integrated into the under tray of the car and a primary coil integrated into a floor plate that can be placed on a garage floor for instance. Electrical energy is transmitted contact-free without the need for a cable, at a power rate of 3.6 kW and with a degree of efficiency of 90%.

World Car Of The Year down to its final four

Judges for the World Car of the Year Award have narrowed down the finalists to just four vehicles. Out of a total of 42 entries, only the Mercedes-Benz A-Class, Porsche Boxster/Cayman, Scion FR-S/Subaru BRZ/Toyota GT-86 and Volkswagen Golf remain standing. For Volkswagen, this marks the second consecutive year the company has had an entry among the finalists, and the fourth time since 2009. In order to qualify, a vehicle must be on sale on two continents during the span of time between January 1, 2013 and May 30, 2013. A panel of 66 journalists from 23 countries then vote on the finalists.
Three vehicles have made the cut for the last round of voting on the 2013 World Performance Car as well, with the Cayman/Boxster and FR-S/BRZ/GT-86 running against the Ferrari F12 Berlinetta. Meanwhile, the Renault Zoe, Tesla Model S and Volvo V60 Plug-In Hybrid are duking it out for the World Green Car Award. Finally, the World Car Design of the Year Award is up for grabs between the Aston Martin Vanquish, Jaguar F-Type, and the Mazda6. Check out the full press release below. Overall winners will be presented at the 2013 New York Auto Show.

Mercedes-Benz engines with 48-volt systems coming in 2017

As part of a big green push announced yesterday, Mercedes-Benz is jumping into the world of 48-volt power. The company will launch a new family of efficient gasoline engines next year and will begin rolling out 48-volt systems with it, likely in its more expensive cars first. Mercedes will use the 48-volt systems to power mild-hybrid functions like energy recuperation (commonly called brake regeneration), engine stop-start, electric boost, and even moving a car from a stop on electric power alone. These features will be enabled through either an integrated starter-generator (Mercedes abbreviates it ISG) or a belt-driven generator (RSG). (RSG is from the German word for belt-driven generator, Riemenstartergeneratoren. That's your language lesson for the day.) Mercedes didn't offer many other details on the new family of engines. There are 48-volt systems already in production; Audi's three-compressor SQ7 engine uses an electric supercharger run by a 48-volt system, and there's a new SQ5 diesel on the horizon that will use a similar setup with the medium-voltage system. Electric superchargers require a lot of juice, which can be fed by either a supercapacitor or batteries in a 48-volt system. Why 48-volt Matters: Current hybrid and battery-electric vehicles make use of very high voltages in their batteries, motors, and the wiring that connects them, usually around 200 to 600 volts. The high voltage gives them enough power to move a big vehicle, but it also creates safety issues. The way to mitigate those safety issues is with added equipment, and that increases both cost and weight. You can see where this is going. By switching to a 48-volt system, the high-voltage issues go away and the electrical architecture benefits from four times the voltage of a normal vehicle system and uses the same current, providing four times the power. The electrical architecture will cost more than a 12-volt system but less than the complex and more dangerous systems in current electrified vehicles. The added cost makes sense now because automakers are running out of ways to wisely spend money for efficiency gains. Cars can retain a cheaper 12-volt battery for lower-power accessories and run the high-draw systems on the 48-volt circuit. The industry is moving toward 48-volt power, with the SAE working on a standard for the systems and Delphi claiming a 10-percent increase in fuel economy for cars that make the switch.
