Cell-to-chassis

Moving to cell-to-chassis architecture means significant changes to EV structures and materials, finds Nick Flaherty Manufacturers of electric vehicles (EVs) are placing increased emphasis on pack design optimisation. Moving from modules to packs and even to direct integration with the chassis can promote lighter weight, less space, higher energy density, and lower material and assembly costs. However, this drive toward cell-to-chassis (C2C) architecture comes with a range of engineering challenges with respect to cooling, materials and assembly processes.

In conversation with Mike Bassett

Mike Bassett, Head of Engineering at MAHLE Powertrain, speaks to Will Gray about hybridisation, EV innovation and why the future of vehicle propulsion has many routes Mike Bassett leads approximately 180 engineers and technicians tasked with innovating the technology behind MAHLE Powertrain’s advanced propulsion systems. Having initially been schooled in the thermodynamics of ICE engines, his route has followed a fascinating path as the world pivots from petrol, via hybridisation, to a currently EV-focused future.

AI and battery management systems

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.

Metal rupture discs offer robust relief

OsecoElfab has developed a family of pressure-relief systems for lithium ion battery applications for heavy-duty, offroad e-mobility applications, writes Nick Flaherty. The low-profile, specialised, metal rupture discs support custom battery design to improve safety. They provide robust emergency relief and pressure equalisation in a single device in the event of outgassing by the battery cells.
