With an initial price of around €30,000, the Novus e-bike is aimed at people who want to make a statement about their embrace of ‘green’ technology rather than those who simply need practical urban transport (writes Peter Donaldson). However, the 30 kW, 400 Nm, 85 kg, all-composite two-wheeler, which was on display at the Battery […]

Sigma Powertrain EMAX transmission

Rory Jackson explains how this modular all-electric gearbox can combine two motors to drive any size and weight of EV. High-voltage electric motors produce torque across a wide range of their rpm bands, enabling most electric cars on the road these days to achieve reasonably high power efficiencies with single-speed gear reductions.

Hydrofoiling gives this serial production boat high speed and long endurance. Rory Jackson examines the engineering decisions behind its design. When it comes to designing new kinds of boat hulls that will get as much power and endurance as possible out of battery-electric powertrains, one of the smartest things a maritime architect can do is simply lift the boat out of the water

Battery swapping, and the alternatives

Whether you drive a single battery EV or operate a fleet of them, ensuring there is enough energy in the battery to complete the job in hand is bound to be a major concern (writes Peter Donaldson). The fact that there are different ways of charging, and that many vehicles can use more than one […]

Supercapacitor applications

Although batteries and supercapacitors both store electrical energy, they do so in very different ways that bestow them with complementary characteristics. In a nutshell, batteries store energy chemically and offer high energy density (measured in Wh/litre) while supercapacitors store energy in electric fields and offer high power density, measured in kW/litre.
