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%.

BMW i3 to start at $41,350*

With a week to go before the global debut of the BMW i3, BMW has announced pricing for its first-ever production electric vehicle. The all-electric version of the i3 goes on sale in the second quarter of next year with a starting price of $41,350 (*not including $925 for destination nor any applicable government tax credits).
Some of the pricing elements for the i3 that BMW continues to withhold are the cost of the model using a gasoline motorcycle engine as a range-extending generator, or that of the DC Fast Charge option. This latter feature will allow the i3's depleted lithium-ion battery pack to get an 80 percent charge in just 20 minutes; for comparison's sake, the DC quick charge feature is a $750 option on the 2014 Chevy Spark EV.
Sure, we've already driven the BMW i3, but the production version of the BMW EV - promising the interior space of a BMW 3 Series - will be unveiled next week at simultaneous ceremonies in New York, London and Beijing. Scroll down for BMW's brief press blast regarding its upcoming i3.

2017 BMW i3 rumored to get more electric range

BMW will reportedly give the 2017 i3 a jolt of extra range that will increase the EV's max driving distance to around 120 miles. If true, that would be quite a boost from the current EPA-estimated 81 miles. An upgraded lithium-ion battery will make this improvement possible, according to Automotive News. Ian Robertson, BMW's boss for sales and marketing, told AN the upgrade to the i3 "puts it into a much more usable range." The company has more tweaks in store for the 2017 model but doesn't want to discuss details about them yet. Rumors late last year hinted that the extra range for the i3 would come thanks to a higher-density battery, improved electronics, and new software. The changes could push range to over 124 miles on the European testing cycle. BMW would also offer the improvements on the i3 REx range-extended model, and the company would even allegedly allow current owners to purchase the upgrades. The German automaker wants to offer these updates every three years to keep the EV fresh. If BMW can achieve 120 miles of range, then the electric i3's driving distance would come significantly closer to the current REx's EPA-estimated 150 miles. Of course, the range-extended model can always be topped up with a tank of gas to keep its wheels spinning further. The i3's rumored boost would also still put it short of the roughly 200 miles that Chevrolet promises from the Bolt when that model arrives late this year. In any case, it's an exciting time for proponents of electric cars. Related Video:
