Bosch does away with the ‘charging brick’

Bosch has unveiled what it says is the world’s first electric car charging cable with integrated technology for flexible recharging without a control box. It also does away with the usual ‘charging brick’ – the bulky in-cable control box – when charging at a 230 V power socket. That allows the cable to weigh less […]

NVH

Peter Donaldson reports on the tools and methods for optimising the acoustic environment in EVs. Of all the disciplines required for developing cars, psychoacoustics isn’t one that readily springs to mind. However, this science of the relationships between aural stimuli and the responses they produce in people informs the branch...

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...

Lanxess launches hollow-profile hybrid technology

Chemicals company Lanxess is launching a hollow-profile hybrid technology. With it, metallic hollow profiles can be made functional on conventional injection moulding machines using plastic compounds. The result is plastic-metal composite components that have far greater torsional stiffness and strength than could be achieved with previous hollow-profile technologies. Potential applications in the automotive industry include […]

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...
