BMW looking to fix i3 acceleration problem uncovered by Consumer Reports

The BMW i3 has been hailed in some quarters as the future of electric mobility, what with its innovative carbon-fiber-reinforced plastic body and commitment to sustainable materials wherever possible. The modernist little hatch is even available with a 650cc two-cylinder gas engine with 34 horsepower to act as a range-extender for those who want it. However, that optional engine might have a drawback - at least for the moment.
Consumer Reports brought the problem to light when one of its drivers was behind the wheel of an i3 using the range-extender. When the driver attempted to pass another vehicle on a rolling, two-lane road, the BMW suddenly had no power to accelerate - a scary situation. CR started examining the car and found something pretty shocking: After driving at a constant speed for a while without any regenerative braking in range-extended mode, acceleration to 60 miles per hour plummeted from about 9 seconds normally to a staggering 27 to 40 seconds in their testing.
A BMW spokesperson told CR that it knows about the problem and has a fix coming next spring that also works on current models. The upgrade includes a state of charge indicator, a warning about loss of power and uses the car's navigation to boost the battery before driving on rolling terrain. It is not clear if the severe power deficiency will also eventually result in a recall.

Recharge Wrap-up: BMW i3 carshare, Audi e-gas plant

Elix Wireless has announced its E10K Wireless Charging System. The system is designed for harsh conditions, delivers up to 10 kilowatts and features automatic detection and removal of foreign objects. Its low frequency makes it safe to operate near oil and gas, and in other hazardous environments. The system can charge personal vehicles, as well as electric buses, trucks, mining equipment and heavy duty machinery. Elix has "created an entirely new technology that meets customer demand for fast, safe and reliable charging," says, CEO David Smith. The E10K system uses Elix's Magneto-Dynamic Coupling technology, with rotating permanent magnets in the transmitter and receiver.

The mobile charging station, which uses second-life EV batteries to charge electric vehicles, will be deployed for a trial at LinkedIn's campus in Mountain View, CA. The Mobi is more flexible than stationary chargers in that it brings the charging to the car, regardless of where it is parked, rather than having to park the EV in a specific spot. It can charge up to five cars per day without putting stress on the grid during peak hours. Read more from Siemens. Audi's e-gas plant in Werlte, Germany helps stabilize the power grid. The plant, which produces synthetic methane using CO2, water and electricity, is able to draw six megawatts of power within five minutes, allowing it to become certified in the electricity balancing market. This helps the grid adapt to the larger load fluctuations that go hand-in-hand with generating renewable energy. It also allows the plant to achieve higher operating times and produce more e-gas each year. Read more in the press release from Audi. The BMW i3 is now available through the DriveNow carsharing service in Germany. DriveNow, which is a joint venture between BMW and car rental company Sixt, has put 100 i3s into service in Berlin, Hamburg and Munich. BMW also says that it supports a shift away from private car ownership in order to improve urban living and mobility, and sees electric carsharing as an important part of that. "We are witnessing the changes our customers and society as a whole are making and we are taking them on board," says BMW's Dr. Bernhard Blattel.

Recharge Wrap-up: Range-extended EV taxis in London, 2016 Chevy Volt interior two years old

The first Metrocab range-extended EV taxis are operating on the streets of London. The cabs use a 12.2-kWh battery and two 50-kW motors, as well as a 1.0-liter gasoline range extender. Fuel economy is 98 MPGe on the ECE101 cycle, and total driving range is over 348 miles before needing to charge or refuel. Cabbies can expect to save GBP20 to GBP40 (about $30 to $60) per day on average. "The cash savings on fuel are significant, the ride and comfort outstanding, and my first customers are thrilled with the new cab," says the first operator of the new EV taxi, Preston Morris. "With its air suspension providing unrivaled comfort, panoramic glass roof for views of the city and silent powertrain, what's not to like?" Read more in the press release below. Chevrolet has had the interior design of the 2016 Volt finished for two years already, according to GM interior designer John McDougall. Beginning around 2010, GM received sketches from designers worldwide before narrowing it down to a handful of designs. Then the top three choices were molded from clay. The chosen theme was then refined for up to 18 months. "Every little thing you can imagine goes into that," says McDougall. "The glare angle from the windows, the placement of the controls, the placement of the seat. You have to create something that's beautiful and functional."

Vattenfall has announced a research project in partnership with BMW and Bosch to use retired EV batteries for stationary, grid-connected energy storage in Hamburg, Germany. Over 100 lithium-ion batteries from BMW i3 and ActiveE vehicles will make up a two-mWh storage unit for grid balancing, enough to power 30 four-person households for a week. The system is "compact enough to fit in a small building," says Bosch. Such storage systems are especially fit for storing and moving alternative forms of energy, which often fluctuate in supply more than electricity from a traditional power plant. Vattenhall will operate the storage unit for 10 years, with Bosch managing the batteries, during which time the three partners hope to learn more about battery applications and their performance over time.
