The Grid

May 23rd 2022

While EVs may have much in common with consumer electronics, the combination of high voltages and powers, and the safety-critical nature of many of their systems, is providing some major headaches for printed circuit board assembly (PCBA) contractors and electronics manufacturing services (EMS) providers – headaches that vehicle OEMs won’t be able to cure with […]

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

Electric trams and trolley buses

In the West we are still addicted to the car as the ultimate embodiment of personal mobility (writes Peter Donaldson). However, there is growing awareness of the total carbon footprint of transport, and even the most efficient electric cars represent large tonnages of carbon dioxide released into the atmosphere in their manufacture. This awareness is […]
