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.

Candela C-7 speedboat
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 […]

Deep Insight
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.

Synergies in testing via the interaction of high-voltage measurement technology and NVH
The increasing complexity of products and components as well as rising demands on testing require new approaches, especially in the field of electromobility. It is necessary to place distributed, high-voltage safe and compact measurement technology for mobile use, or permanently installed in the test bench, with powerful data acquisition and analysis software directly at the […]

NIO unveils standard-range battery with better performance in colder weather
NIO has launched a new standard-range 75 kWh hybrid-cell battery it says will reduce range loss in low temperatures by 25%. It adds that the battery also gives a more accurate state of charge (SoC) estimate while matching the battery performance of a ternary lithium battery. The battery is a hybrid of ternary lithium and […]
