Dyno development

For ICE powertrain companies looking to transition into e-powertrain engineering, theconstruction of new test cells poses one of the biggest cost-barriers to entry. High-speed dynamometers and test benches capable of measuring the performances of e-motors are inevitably pricey, and many such companies already possess significant testingequipment for cycling combustion engines. However, conventional ICE dynos are […]

Skateboard platforms

Against the backdrop of a boom in skateboard platforms for EV designs, Nick Flaherty looks at the approaches taken by some of their suppliers. Changing the wheelbase of a traditional car or truck design by 6 or 7 in creates a ripple effect whereby half the transmission shaft has to be redesigned, changing the centre of gravity and the requirements for the suspension. That means a whole new vehicle design is needed...

Condition monitoring

Peter Donaldson examines the factors involved in keeping tabs on the health and performance of key EV components. While an EV’s most costly component is its battery, there are also many other subsystems – inverters, generators and so on – whose condition is critical to safety and efficiency. Machinery health and usage monitoring is well-established...
