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...

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...

Fuel cells

Nick Flaherty explains the issues at play when designing and building a fuel cell. Sometimes it seems that the specification and design of a fuel cell is more of an art than a matter of engineering. While the basics of the cells are clear, most often based around a stack of proton exchange membrane (PEM) cells...

vRbikes vR3

Rory Jackson looks at how this three-wheeler has been designed to carry as much cargo as possible in the smallest footprint possible. Given that an electric powertrain brings with it lower maintenance times and costs compared with ICE powertrains, so more and more EV developers are looking to ‘right-size’ their vehicles into smaller and more compact architectures, for ease of use and...

Battery Show North America 2019 Part 2

Rory Jackson follows up his first report from this show with further highlights of the products that were on display. There were so many new innovations at The Battery Show – its largest to date – that we didn’t have room in our previous issue (Winter 2019) to highlight all the ones we...

E-axles

Peter Donaldson canvasses some Tier 1 suppliers’ views on contemporary e-axle technology and the likely future trends in their design. Integrating a motor, gearing and power electronics into a compact, modular package that sits between a vehicle’s driven wheels creates a system that has come to be known as an e-axle. It is an increasingly attractive option for...
