E-MOBILITY ENGINEERING 025 – May/June 2024

• Intro - Engineers are working towards the ‘Plateau of Productivity’ when it comes to designing the tech of the future
• The Grid - E-mobility power management standard, eVTOL vehicle with US certification, building lighter components with 3D-printing, propulsion boost, doubling battery density, electron beam welding, and more…
• In conversation: Dr Richard Ahlfeld - Monolith’s CEO has worked on NASA’s space systems and now he is improving powertrain development roadmaps with AI
• Dossier: H2D2 snow groomer - A project is making it happen for ‘possibly the hardest type of vehicle to electrify’
• Focus: Battery sealing - Why choosing the right material and process can be tricky
• Insight: Coil windings - Electric machines are not as simple as they look and coil windings have a crucial role to play in magnetic attraction
• Digest: Electrogenic E-type conversion - One developer of electric powertrains is carrying out bespoke conversions of classic models
• Deep insight: Battery energy density - An array of strategies are being used to get more oomph out of battery cells, bringing thermal management challenges
• Focus: Thermal runaway prevention - Stopping thermal runaway starts with cell engineering and design, and electrochemical development
• PS: Battery repair and recycling - An uncomfortable truth is that EV batteries have higher than expected failure rates and they are costly to repair, while their actual condition is difficult to assess
