Anyone who says there can never be commercial electric aircraft or fastcharging EVs are not taking into account the advances that can be achieved by optimising every element in the powertrain, from the energy source to the inverter and then the motor. This is illustrated by some of the articles in this issue. On page 58 for example, designers of electric motors for aircraft say the technology for electric flight is available, but it is the range and the certification challenges that are taking up engineering time at the moment. At the same time, on page 20 Nyobolt has been demonstrating its fast-charging battery packs in a modernised Lotus Elise, showing charging times of just a few minutes. And on page 16, Verge Motorcycles has also been pushing the limits of performance with the end-to-end design of its machines, and we talk to its CTO Marko Lehtimaki about the developments in that respect. All these e-mobility systems need the latest technology for assembly, so our focus on busbars and interconnects (page 64) and battery welding (page 44) consider the different ways in which e-mobility platforms can be assembled reliably and cost-effectively.
