Automobiles are trending towards electric power – but what about their counterparts in the sky? Jet fuel and aviation gasoline are very energy-inefficient, but they have one big advantage: they’re lightweight. Every gram matters in the aerospace industry. That’s why electrifying an aircraft is so difficult: although batteries would be much more efficient than jet… Read more »

AxleTech’s highly integrated e-axle for medium- and heavy-duty commercial trucks
Sponsored by AxleTech Widescale commercial vehicle electrification requires intelligent systems engineering Electrification continues to gain traction throughout the commercial vehicle industry. Driven primarily by rapidly falling battery costs, and thus lower total operating costs, vehicle makers are racing to electrify existing models and launch all new electric vehicles. Tightening emissions regulations and corporate social responsibility targets… Read more »
Siemens and VW to test long-haul trucks charged by overhead power lines
The German Federal Ministry for the Environment has approved a subsidized pilot project to research the electrification of long-haul trucks using a roof-mounted pantograph to charge from an overhead power line. Siemens will be responsible for developing the pantograph, and Volkswagen will provide hybrid trucks via subsidiary Scania, and will carry out the research. Trial… Read more »
Making a motor: Many automakers rely heavily on third party motor-winding experts like Odawara Engineering
Electric motors are everywhere: in household appliances, in hand tools, in buildings, in consumer electronics, and increasingly in automobiles. Motors are used in windshield wipers, power windows, throttle controllers, and, more and more, in the drivetrains of electrified vehicles. Electric motors abound, and Odawara Engineering knows how to make them. Charged spoke with Odawara’s Chris… Read more »

The new P1166 is featured in Williams Advanced Engineering’s FW-EVX lightweight EV platform concept, which Williams unveiled at the recent Low Carbon Vehicle Show in Millbrook, UK. The P1166 transmission, fully integrated with a YASA P400 motor-generator, powers… Read more »
Flying electric: Both startups and industry giants push ahead with electric airplanes
In the popular imagination, aviation represents the last frontier for electrification. Considering the weight and limited range of batteries, an electric airplane might seem practically impossible. However, while electric long-haul airliners probably lie pretty far in the future, the fact is that, in some applications, the technical obstacles to electrified aircraft are not as formidable… Read more »
