E-MOBILITY ENGINEERING 030 – March/April 2025

• Intro - The age of the affordable EV has finally arrived, along with improvements in e-mobility engineering, boosted by AI, stronger cybersecurity and optimised testing techniques
• The Grid - Cutting battery development times with machine learning, an emulator for a 20 MW charging system, reducing on-resistance in e-bike designs, the world’s first fully-electric offshore sea vessel, the joy of silicon nitride ceramics, pulsating heat pipes, and much more
• In conversation: Tony Fong - A self-confessed “tinkerer” of electrical systems, Everrati’s head of engineering is revving up old, luxurious classics with the latest powertrains
• Dossier: Bobcat T7X electric compact track loader - In 2018, Bobcat identified compact track loaders as ideal for electrification and today it is making construction more sustainable with the T7X
• Focus: Cybersecurity - Developers are coming up with new ways to make e-mobility safer and more secure
• Insight: Motor testing - Electric motors at the heart of the propulsion system of EVs of all kinds must undergo intensive testing, involving many different technologies and procedures
• EVD: Charge Qube - Fellten’s containerised system stores energy in repurposed battery packs and can charge many of them simultaneously
• Deep insight: HIL testing - Combining digital models of components with simulations to create a digital twin of a vehicle that can be driven before it has been built – feeding the results back into the design
• Focus: Battery leak testing - Reliable and accurate leak detection is essential at every stage of a battery’s life – from manufacturing to storage to in-service use, repair, recycling and disposal
• PS: AI and battery management systems - Meeting the challenge of incorporating AI and machine learning into BMSs to reap the myriad benefits on offer
