E-MOBILITY ENGINEERING 037 – May/June 2026

• Intro - Recent e-mobility technology trends include boosting performance with hydrogen power, adopting lightweighting practices in chassis design, enhancing the quality and safety of batteries and improving production test systems
• The Grid - Power converters for higher-power e-bike chargers, revolutionary packaging technology for smaller, isolated power modules that pack more punch, battery designs that extend EV range, a model for predicting battery RUL, the fastest private submersible ever built and much more
• In conversation: Jurij Kern - A career spent at the centre of in-wheel motor technology development might just be about to produce a revolution in automobile architecture
• Dossier: SeLv project - In an ambitious attempt to tackle the problem of reducing long-distance haulage emissions, the SeLv project demonstrates the potential of hydrogen fuel cells as range extenders for use alongside batteries in EV trucking
• Focus: Production tests - Challenges in production testing must be overcome if automakers and EV supply equipment manufacturers are to keep up the projected volume of electric car sales globally
• Insight: Battery manufacturing - Translating lab-based promise of battery performance into mass-produced reality is one of the most complex industrial challenges of the e-mobility era
• Deep insight: Lightweight chassis bonding - Lightweighting is becoming an increasingly important aspect of how the auto industry is responding to environmental regulations around range and emissions
• Focus: Battery safety - Preventing thermal runaway is the most critical safety challenge in battery pack design; one that requires an integrated system solution
• PS: Fleet-level battery state of health - Large-scale analysis of battery state of health revealed that EV batteries are more durable than public perception might suggest
