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...

Lightning Strike electric motorcycle

Stewart Mitchell explains how this road-going machine was developed to take on the ICE competition – at a competitive price. Lightning Motorcycles is an all-electric motorcycle manufacturer that produces the LS-218 ‘superbike’ and the more affordable Strike, which is pitched head-on against gasoline-powered alternatives. Founder of the San Jose, California company Richard Hatfield says...

Andrew Cross

Integral Powertrain’s CTO tells Rory Jackson how he has come to lead the company’s development of high performance consumer EV drives. One of Andrew Cross’ most prominent early memories is the engineering company his father owned and ran, designing and manufacturing polymer parts, and developing much of his own production systems and tooling...

Battery Safety

The EV battery industry offers a variety of ways to minimise the hazards they can pose, as Peter Donaldson explains. Proximity to large amounts of energy has always presented hazards, but people have mostly learned to live with them and enjoy its benefits. However, being close to a high-energy electrochemical system such as a 100 kWh battery is still...

Rather than go all-out on the technology, this EV has been conceived with reusable components – and the circular economy – in mind. Rory Jackson reports. End-to-end sustainability is a troublesome target for EV engineers to track. Reducing vehicle emissions at the point of use is easy enough, but reducing the emissions...

Tesla Octovalve analysis

It’s not often that we get the opportunity to dig into the details of an important EV subsystem from the point of view of an independent engineering team, but that is what Cory Steuben of Munro & Associates provided at the recent Battery Show and EV Tech online event (writes Peter Donaldson). The subsystem was the Tesla Model Y’s heat pump, in particular...

Vehicle-to-grid charging

Although bidirectional charging for EVs remains a niche technology, writes Nick Flaherty, progress on its uptake is being made. Vehicle-to-grid (V2G) charging is an appealing technology, as it enables EV batteries to be used as part of the electricity grid to even out demand. For example, electric car owners could charge their...
