Fellten Charge Qube

  By


Peter Donaldson investigates a containerised system that can charge multiple vehicles and doesn’t need a grid connection.
Until the electric power grid is able to support fast charging for EVs everywhere, there is likely to always be a market for something like Fellten’s Charge Qube – a containerised system that stores energy in repurposed battery packs and can charge multiple vehicles simultaneously, with or without a connection to the grid.

HIL Testing

  By


Nick Flaherty traces the line where digital models of components meet simulation to experience a vehicle before it is even built
Virtual design methodologies are increasingly being adopted in the development of e-mobility platforms – combining digital models of components with simulation to create a digital twin of an entire vehicle that can be driven before it has even been built. Read more…

Battery leak testing

  By


Peter Donaldson delves into the world of battery leak testing.
With the exception of old, British motorbike engines – it was said that if they’re not leaking, there’s no oil in them – leaks from anything are usually a sign of a problem.
The escape of liquids such as coolant and electrolyte are undesirable, and the emission of gases can be the first warning sign of a thermal runaway. Read more…

AI and battery management systems

alt=’E-Mobility Engineering’>
AI is with us and it’s being incorporated into battery management systems (BMS), but its implementation faces challenges, writes Peter Donaldson.
Machine learning (ML) is applied to improve the accuracy of state estimation, with neural networks and support vector machines analysing historical data, and driving patterns and environmental conditions to estimate, predict and optimise battery states of charge, health and power. Read more…

Doosan Bobcat T7X

  By


Doosan Bobcat is using electrification to not only reduce emissions in construction but also radically change the operation of compact track loaders, reports Will Gray
Construction is not the first industry you think of when it comes to sustainability or electrification. Heavy, power-hungry machines do not immediately suggest the ideal platform for battery-powered performance, yet Bobcat has discovered the opposite, with its new T7X compact track loader outperforming its diesel-powered equivalent in almost every area.

Everrati’s head of engineering discusses novel ways of electrifying classic cars with Will Gray
Electric vehicle (EV) technology is moving at a rapid pace and much of that is thanks to people like Tony Fong. As head of engineering at luxury electric car company Everrati, he is pioneering cutting-edge innovation in the most unlikely of places – by implanting the latest powertrain components into old classics to create the systems of the future.

Motor testing

  By


Peter Donaldson examines various means of testing electric motors.
Although mechanically simple, compared with internal combustion engines, the electric motors forming the heart of the propulsion system of EVs of all kinds must go through intensive testing. This involves the use of many technologies and procedures to probe performance, efficiency, reliability and safety at every stage of manufacture and integration. Read more…

Scania enhances e-bus offering with new e-machine, battery and charging options

  By


Scania’s new e-machine is fully adapted to the company’s complete battery-electric bus platform. Four power options are now available, and an integrated two- or four-speed gearbox, offering an impressive combination of increased performance and efficiency, flexibility and zero emissions. A further battery option has been added, and a charging interface at the rear of the bus will quicken power uptake. Read more…

New manufacturing innovations offer EV weight loss

  By


The quest for greater efficiency and range in EVs is often focused on battery technology and drivetrain efficiency, but fundamental physics point to another key factor in the equation: weight. The increasingly popular move from 400V to 800V systems saves weight through lighter cables, but even reductions of a few kilogrammes can make a tangible difference and one company is exploring innovations in sheet metal that could change the game.
