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.

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: Houston's bus revival, autonomous trucks on the Autobahn

A documentary shows how Houston, Texas significantly improved its outdated bus system. Called High Frequency: Why Houston is Back on the Bus, the short film describes how the city reimagined its bus system to become more efficient, more useful and more popular. Despite some opposition, the change has proven to be effective, with bus ridership up eight percent in three months, and light rail ridership up due to complementary bus routes. See the video above, and read more at CityLab. Automakers sent autonomous semi trucks on the German Autobahn as part of the European Truck Platooning Challenge of 2016. Mercedes-Benz, Volvo and Scania, among other groups, sent platoons of trucks between Stuttgart, Germany, and Rotterdam, Holland. In Mercedes's platoon of three trucks, the lead truck was fitted with lasers and other sensors to guide the convoy down the road. The two following trucks relied on vehicle-to-vehicle communication to trail 50 feet behind the lead, making room for cars to come between them and closing the gaps when able. The close following distance provides fuel economy gains of up to 10 percent in the rearward trucks on account of the reduction in drag. Read more at Hybrid Cars. Renault has reduced NOx emissions in its Euro 6b diesel vehicles in real world driving conditions. By improving its exhaust gas recirculation systems and NOx traps, nitrogen oxide emissions are cut in half on average, under certain driving conditions. The improvements will be included in vehicles leaving the factory beginning in July of 2016. Beginning in October, owners of Renault Euro 6b diesels can have the modifications added to their cars for free. Read more from Renault. Tata Technologies is creating an innovation lab in California to partner with EV technology companies. Having a tech center in California allows Tata to work on technologies that will largely be deployed in the company's main market of Asia. "Today, we are partnering with companies and startups who have aspirations to sell in China, but a lot of what they do is in California," says Samir Yajnik of Tata Technologies.

RideCell provides technology for services such as carsharing, ridesharing and other transit services. "The convergence of transportation trends in cities is of key importance to BMW," says Ulrich Quay, head of BMW i Ventures.
