Oak Ridge tests inductive bi-directional charging
Researchers at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) have successfully developed and deployed a bi-directional inductive charging system on a UPS PHEV delivery vehicle. Bidirectionality was not the only feature of the experiment. Weiterlesen

Inductive charging collaboration: Until now it seemed that Daimler and BMW were working together with Brusa to develop inductive charging technology. But now Daimler announced that it will team up with Qualcomm to develop wireless charging solutions based on the latter’s Halo WEVC technology.
Wireless in-wheel motor: Japanese researchers say they have successfully developed the world’s first in-wheel motor system for electric cars that transfers electricity from the battery to the in-wheel motor wirelessly. It features a transmitting and a receiving coil located ten centimeters apart.
Schaeffler joins Formula E: As the exclusive technology partner of Team ABT Sportsline, Schaeffler is already developing an electric motor of its own for the second Formula E season and will be shaping the entire powertrain system of the motor and transmission for the race car. The first components will already be tested in the next few weeks.
New solid-state electrolyte: Researchers at the Oak Ridge National Laboratory say they have developed a promising new solid-state electrolyte for rechargeable batteries with lithium-metal anodes. The material (Li7P2S8I) stands out due to its high ionic conductivity and chemical stability.

Extra fast-charging aluminum battery: Researchers from Stanford University have developed an aluminium-ion battery which the team claims to be safe, fast-charging and yet stable for more than 7,500 cycles without any loss of capacity, while being comparatively cheap. The Al-ion power pack is comprised of an aluminum anode, a graphite cathode and an ionic liquid electrolyte.

Battery simulation: A team at the Oak Ridge National Laboratory introduced its Virtual Integrated Battery Environment (VIBE). VIBE has been developed with funding from the DoE and enables battery makers to test their battery designs under various simulated scenarios.
Solarbike: This new speed pedelec prototype from Denmark rejoices its battery through solar panels covering both wheels. With the battery charged, the Solarbike’s central motor pedal-assists its driver at a top speed of 30 mph. Only after 43 miles the bike needs a sunbath.

New 3-D printed electric car: Oak Ridge Laboratory showcased a 3-D printed Shelby Cobra replica equipped with an electric powertrain from TM4. The car was printed using 20% carbon fiber reinforced ABS material. The design allows integrated components to be tested and enhanced in real time.
Human-powered vehicles in Detroit: “The Future People” presented its Cyclone and Zeppelin at the NAIAS. Both “future cycles” are powered by pedalling and are supported by an electric motor. The Zeppelin, for instance, has a 750 watt electric rear motor and reaches up to 25 mph (40 kph).
FE School Series debuts in Buenos Aires: As part of the Formula E racing series, 11 to 16-year-old students built and drove a total of ten Michelin-shod Greenpower Formula E cars. Six kids competed per team in a 20 minute race. The same format will also be found as a support race during the ePrix in Miami, Long Beach, Berlin and the final in London.
Squishy EV: Spira4U showed off its small car made entirely of foam and plastic in Detroit last week (we reported). Frank Markus drove the car and found out that “there’s plenty of electric motor whirring to be heard, and even at less than 20 mph, wind can be detected whizzing by the sliding side windows.”

Exact range indicator: A new software developed at the North Carolina State University is said to be able to calculate an EV’s range more exactly than others. It uses multiple online databases and considers factors such as road grades, traffic levels, speed limits and even the weather.
Fuel cell REx from Sweden: The Volvo Group spinout PowerCell receives 7 million Krona (963,000 USD) in funding from the Swedish energy agency, in order to develop a modular and scalable fuel cell system for commercial vehicles. It is supposed to be used as a range extender for three different vehicle sizes, ranging from 3.5 to 18 tons.
Ireland will head the Shell Eco-marathon for the first time next year. The National University Ireland, Galway, has designed the country’s most fuel-efficient car. The Geec (Galway energy-efficient car) can travel about 180 kilometres on just one euro worth of energy.
Seperator research: Scientists from the US Department of Energy’s Oak Ridge National Laborator have discovered a “promising candidate” for the separator in aqueous lithium batteries. They report that a cubic garnet material (LLZO) is highly stable as a Li-stable solid electrolyte in neutral and strongly basic solutions.

Smaller yet stronger: Researchers from Oak Ridge National Laboratory have created a prototype inverter using 3-D printing and silicon carbide (SiC) wide band gap (WBG) semiconductors. It is said to have much higher power density, while being lighter and smaller than inverters currently on the market.
Torque vectoring transmission: Researchers of the Visio.M project at the TU Munich have come up with a lightweight torque vectoring system for electric vehicles. It distributes torque between the wheels as required, providing safer road handling and allowing for more energy to be recovered while braking.
