BMW moves to two-motor architecture

BMW is using two different types of motor in its sixth-generation electric powertrain, writes Nick Flaherty. The Gen6 eDrive system rolling out later this year redesigns the powertrain for 800 V operation, and adopts cylindrical rather than prismatic cells that are part of the vehicle’s structure.

Overmould rib process for electric aircraft

The National Institute for Aviation Research (NIAR) at Wichita State University has developed a thermoplastic rib structure to simplify the manufacture of eVTOL systems, writes Nick Flaherty. The fully automated hybrid thermoforming and injection overmoulding process cuts production time from 100 hours to two minutes, marking a major breakthrough in aerospace manufacturing efficiency. By integrating two key polymer processing techniques, the process enables production of high-performance, lightweight components with greater design flexibility and cost efficiency.

AI for battery material discovery

SandboxAQ has developed a new approach to using artificial intelligence (AI) for the discovery of new battery materials, writes Nick Flaherty. The company has combined a chemical simulation platform with the transformer AI frameworks in large language models to create what it calls a ‘large quantitative model,’ or LQM.

Electric ferry targets 2026

Incat in Australia is constructing a 78 m hybrid electric ferry that will be ready for operation in the first half of 2026, writes Nick Flaherty. The 78 m craft, as yet unnamed, has flexible propulsion options with a fully electric battery system of up to 12 MWh as well as hybrid and generator-assisted options. The system supports charging at rates up to 10 MW to reduce the turnaround time.

Robot charging for Rotterdam

Rocsys has demonstrated its robot self-charging system working with electric trucks in a port in the Netherlands, writes Nick Flaherty. The Rocsys platform includes the first interoperable robotic hands-free charging system for ports, logistics and robotaxi industries. The demonstration was part of the European Magpie project to automate activity at ports and logistics centres.

Battery pack designed for second life

A European project has developed a battery prototype designed for ease of assembly and disassembly of battery components, writes Nick Flaherty. The battery pack developed as part of the MARBEL project with car maker Stellantis uses a wireless battery management system (BMS), artificial intelligence (AI) and a digital twin capable of predicting a battery’s remaining useful life, as well as its state of charge and health.
