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.

Twizy truck: On Twitter, Renault posted a picture of its Twizy featuring a one square metre large cargo area. The six-wheeled Twizy delivery concept was conceived as part of the VELUD (Electric Vehicle for Sustainable Urban Logistics) project and will first be tested in Paris. If it ever makes serial production, remains to be seen.

Hyperlooping Texas? Tesla CEO Elon Musk announced he wants to build a test track for the Hyperloop train – most likely in Texas. There, students and companies will be able to test their prototypes that run up to 4,000 mph. Musk is even considering an annual pod racer competition. The deal with Texas is also part of Tesla’s move to the U.S. state to allow Tesla stores.
Schaeffler showed its line-up of engine technologies in Detroit, allowing carmakers to meet 2025 CAFE (Corporate Average Fuel Economy) requirements. It also presented a close-to-production vehicle based on a Ford Kuga that already meets the standards due to its mild 48V hybridization.

Prius fighter? The new Volt’s drivetrain has two motor-generators with its total drive power of 111 kW (149 hp). While one motor acts as a 45-kW generator, it can be used as a second motor to provide extra torque. Green Car Reports believes it could be GM’s technological answer to the upcoming new Prius.

Mild-hybrid SUV: Schaeffler will show the second phase of its concept car based on an all-wheel-drive, midsize SUV at the North American International Auto Show in January. Including a 48-volt system and other innovations, the vehicle already meets 2025 CAFE requirements.
Electric donkey: Shown at the IAA Commercial Vehicles show in Hanover earlier this year, the Kulan electric utility concept was created by a German consortium of 14 companies and research organisations and is designed for transporting loads around farms. With just about 4 kW from two electric motors – one in each rear-wheel hub – it is able to carry one tonne of cargo.
Li-ion research: Researchers at the University of Maryland say they have improved the cycle life of silicon-carbon composite electrodes by 300 percent. This was achieved solely by the chemical tailoring of the interface between the silicon and the carbon with atomic oxygen.
Lithium-sulfur research: Researchers at the University of Texas have found that using phosphorus pentasulfide (P2S5) as an electrolyte additive enables the direct use of commercially available bulk Li2S particles as high-capacity cathode materials for Li−S batteries. According to the researchers, this could significantly decrease the manufacturing cost of Li−S batteries.
Intelligent e-bike: The Netherlands Organisation for Applied Scientific Research (TNO) has developed an electric bike that is able to detect oncoming dangers and warn its rider by vibrating either the handlebars (danger from the front) or the saddle (danger from the back). The radar and camera-assisted safety bike could be available to customers within the next two years.

Fuel cell range-extender: The 25 kW fuel cell system HyRange 25 FC can power buses, as well as light and heavy duty vehicles. But Proton Motors hopes to mainly use it as a range extender for EVs. The modular system is based on Proton Motor’s PM400 fuel cell stack and can be combined to 50 and 75 kW configurations.
Automatic pedelec gear shift: Schaeffler will present its Fag-Velomatic for (e-) bikes at the Eurobike show. The transmission comes with the Velodaptic app that gathers GPS and performance data. The FAG-Velomatic measures cadence, force, speed and gradient for shifting, while cyclists can also adapt their profile via the app.
Talking carbon: According to Reuters, South Korea’s GS Caltex wants to meet with Tesla, which has entertained the idea of using carbon fibres for some time now. Meanwhile, a study by the German army (Bundeswehr) reports that fumes emitted by burning carbon fibres (i.e. when in a crash) could cause cancer.

Electric truck conversion: ZeroTruck is converting medium-duty trucks. The company’s Electric Drive Integration System (EDIS) is funded by the California Energy Commission but has been in operation since 2010. The system has a top speed of 70 mph and a range of up to 80 miles.

Schaeffler, Prodrive, RocketSkates, BMW.
Gears for efficiency: Schaeffler presented its latest concept vehicle STEP2 at the Silvretta electric car rally. Their converted electric Golf’s new two-speed transmission is said to use six percent less energy, than similar vehicles with a single-gear drivetrain.
Silicon carbide converter: A consortium of British companies led by Prodrive developed a high-frequency DC-DC converter with a efficiency of 98.7%. The converter, which is currently fitted to a Tata Vista test vehicle, acts like a hub connecting high voltage battery, motor, a super-capacitor bank and 12-volts auxiliary system.
Wearable mobility is what Acton classifies their RocketSkates as. These skates are not propelled by rockets but by small electric hub motors, allowing for a speed of up to 12 mph. Within just 24 hours, their Kickstarter campaign raised more than enough money to fund the project.
Time-saving repairs: The BMW i3 is a revolutionary car, also in terms of fixing it after an accident. Instead of just pounding out damaged parts, the CFRP panels need to be replaced completely. Because this takes less time, the i3 is not any more expensive to repair than a BMW 1 Series car.

48-volt concept: At the Vienna Motor Symposium, Schaeffler and Continental presented a mild hybrid in what they dubbed the ‘Gasoline Technology Car’ (GTC). Based on the Ford Focus the GTC is said to use 17% less gasoline than a conventional compact car.
Less platinum, longer life: Researchers at the East China University of Science and Technology in Shanghai found that new platinum-iridium alloy catalysts for PEM fuel cells led to a “drastic” improvement in durability and stability while using 50% less platinum.
Even less platinum: A new electrospinning/electrospraying (E/E) technique for fuel cell electrodes results in high power densities with ultra-low platinum loadings. The method which produces a nanoparticle cathode catalyst layer has been developed by researchers at Drexel University, USA.
Nigeria’s first electric car has been built by student Segun Oyeyiola. His conversion of a VW Bug features a solar roof and is said to come with enough range for the family’s daily errands.
