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%.

Bristol returning under BMW power

BMW has had its hand in reviving once-great British automakers, and now its playing its part in the rebirth of another. That marque is Bristol Cars, the automotive offshoot of the Bristol Aeroplane Company. Bristol hand-made luxury sports cars between 1945 and 2011 when it went belly-up, and ever since there's been an effort to bring it back. That effort is now picking up steam, and is set to launch later this year – marking the 70th anniversary of the marque's founding. It's tentatively known as Project Pinnacle, and while future versions are slated to pack plug-in hybrid power developed in collaboration with Bristol's sister company Frazer-Nash (which is now focused on battery technology), the first new Bristol in a dozen years is slated to pack BMW power. Details accompanying the announcement below are few and far between, but one way or another, it won't be the first time BMW will have played a part in breathing new life into a British automaker. The Bavarian company of course revived Mini, and made Rolls-Royce what it is today, but was also was briefly the custodian of Rover, Land Rover and Bentley, and has been linked to a potential (if unrealized) effort to bring back Triumph. Its role in Bristol's rebirth under Project Pinnacle may be less involved than all of those, but at very least we'll know that the new British GT will have a proper engine under the hood. BRISTOL CARS CONFIRMS POWERTRAIN FOR 70th ANNIVERSARY PROJECT PINNACLE • First new Bristol car in more than a decade to feature BMW powerplant • High performance powertrain earmarks resumption of the history between Bristol, Frazer-Nash and BMW dating back to 1930s London, England, June 2015 – Iconic British carmaker, Bristol Cars, makes the second in a series of announcements today about its first new car in more than a decade, codenamed Project Pinnacle. Project Pinnacle, which is set for launch later this year, will be a 70th anniversary celebration model, referencing Bristol Cars' rich heritage and executed as a modern take on the best of British craftsmanship, engineered to excite and satisfy as a high performance Bristol car. Bristol Cars is deeply proud to announce that the machinery underpinning this high performance new vehicle will be a BMW powerplant. The result will a sublime British sportscar with characteristics cultured uniquely for the first new Bristol since 2004.

BMW exec says public chargers not important for EV success

What has BMW learned from years of electric vehicle test programs and working with Mini E drivers and the ActiveE Electronauts? According to BMW board member Herbert Diess, it's that public charging is not an important piece of the puzzle of making EVs a success. The way those early EV drivers used their vehicles told BMW that, "public infrastructure is not really very important because most people are charging their cars at home," Diess recently told Wards Auto. It's a message we've heard before. Diess' personal experience fits with this conclusion, he said. After driving his company's new i3 city EV for over a year, "not once have I touched public charging." Of course, the i3 does let the driver search for public charging stations and BMW has a partnership with ChargePoint, and Diess is not hinting that BMW is totally against the idea of public charging. Still, Diess' comments are not likely to find a warm welcome with everyone in the EV scene. An August 2012 UCLA study titled "Financial Viability Of Non-Residential Electric Vehicle Charging Stations" (PDF) clearly states: Adoption by consumers will largely be a function of the electric vehicle charging options available. Studies show that most EV charging currently takes place in the home (Carr 2010). Even so, in order for EVs to gain widespread consumer adoption, it is critical for an infrastructure of electric vehicle supply equipment (EVSEs) to exist outside the home. Even BMW's own electric drivers have been sending mixed messages. In 2010, a study of Mini E drivers found that 87.5 percent said a public charging infrastructure is necessary, though 75 percent later said they could manage without such a network.
