Harley-Davidson's e-bike shocker (video) Is the motorcycle market ready for a Harley-Davidson EV? Project LiveWire was designed to provide answers, said Chief Engineer Jeff Richlen. Airbus has its eye on the future of cleaner flight CleanSky 2 targets are to increase aircraft fuel efficiency enough to reduce CO2 emissions by 20-30% and reduce aircraft NOx and noise emissions by 20-30% compared to newly designed aircraft entering into service in 2014-or essentially halve 2005 CO2 emissions levels by 2050. Soul EV extends the range frontier (video) Specially formulated NCM battery cells are key in giving the vehicle class-leading EV range while enabling engineers to fit a high-energy-density battery pack underfloor with little sacrifice of passenger cabin space.
Inside the cell walls The high cost of lithium-ion batteries is a prison that has largely kept electric vehicles off the street; the keys to their release are more effective—but not more expensive—cell chemistries.
Fuel cells for auxiliary power OEM and supplier researchers explore the benefits of utilizing solid-oxide fuel-cell APUs to help meet heavy-duty truck anti-idling requirements. Safer EV batteries could enter the crush zone ARPA-e targets "robust" batteries that not only bear loads but also absorb crash-impact energy to save weight.
Lithium-ion refinement Even as high-profile fires create concern, battery and car makers accelerate their move toward lithium-ion technology with advances in cost, performance, and safety. NASA's quest for maximum efficiency As part of its hybrid body wing aircraft with turboelectric distributed propulsion system, NASA has proposed to use a superconducting and cryogenic electrical system to connect the electrical output of the generators to the motors.
In hybrid systems, mild beats wild The coming wave of 48-v mild hybrids aim for maximum benefit at minimal cost.
No more molecules! Companies continue to invest in new chemistries for EV batteries, but at least one company in the battery industry thinks it's time to halt the unending search for new chemical formulations and focus on driving down processing costs.
Argonne heats up Li-ion battery research The U.S. Department of Energy lab near Chicago is using federal stimulus money to dive deeper into lithium battery research. Lithium-ion battery industry moves forward From technology advances to manufacturing capacity expansions, the foundation of the lithium-ion battery industry is becoming stronger and more viable.
Bang for the buck The best technology solutions for electrified vehicles are the ones that deliver ∼80% of the performance of 'ideal' systems, at ∼60% of their cost. Rise of the P2 machines Newcomers to hybrid-vehicle development are bypassing the Prius-proven powersplit system for lower-cost and moderately less capable single-motor solutions. Rethinking battery and e-motor materials Experts reveal efforts to find lower cost, more strategically stable solutions that can match or improve system performance.
The buzz about electric aircraft Emissions limits force the aviation industry to study hybrid and battery-electric propulsion systems. Car-to-X marks the secure beamforming spot Intelligent networking of cars and infrastructure promises a future of enhanced active safety and traffic efficiency, though as an open and decentralized system, car-to-X is exposed to various attacks against security and driver's privacy. Talking big A look at factors that should be considered by OEMs when implementing a telematics solution in the heavy-duty on- and off-highway mobile equipment markets.
One souped-up EV North Carolina-based Li-ion Motors draws upon the region's motorsports heritage to engineer and build what it calls the world's first all American-made electric supercar. Inductive charging gets green flag U.K.-based start-up HaloIPT partners with Drayson Racing to bring 'dynamic' wireless charging to electric racecars.
Prime time for batteries Forecasts very on how many, and when, electrified vehicles will hit the streets, but auto and battery makers are ramping up efforts like there's no tomorrow. In energy storage, materials matter Batteries being electrochemical devices, innovation and advances in chemistry and materials are key to what everyone agrees is the need for improved performance and life. Comparing thermal characteristics of Li-ion celss Most Li-ion battery suppliers require that the cell temperature be as uniform as possible to achieve optimal battery performance and avoid battery system failure. But some materials in Li-ion cells have low thermal stability. The world plugs into EVs As matters begin to settle in terms of connector types, charge-station makers are ramping up to meet the needs of a growing population of plug-in vehicles.
Why Volt? After 48 months' development, the 2011 Chevrolet Volt has enetered series production. The pioneering "E-REV" is as important to the mobility industry as it is to GM. Creating the heart of Volt GM's battery requirements meant creating new state-of-the-art in-vehicle engery storage - and doing it in less than four years. Top GM and supplier engineers reveal how they did it. Engineering with maniacal focus A dedicated, cohesive team and a conservative engineering approach put this innovative vehicle into production at moon-shot speed. A unique electrified transaxle Hybrid or not? Definitions aside, what really matters is GM wisely leveraged its next-generation Two Mode propulsion technology to give Volt greater overall efficiency. Sweating the body details Extensive wind-tunnel work gave Volt a shape that's slicker than it looks. But engineers aren't happy with the curb weight.
