How Camfil cleans up the battery production process

Battery anodes and cathodes are typically made from slurries of active chemical powders and supporting substances such as binders and solvents applied to foil substrates, before being dried, cut and combined into ‘jelly rolls’ or laminates to form the core components of cells (writes Peter Donaldson). The process inevitably...

Xerotech battery system

Unlike road EVs, off-highway vehicles need different battery solutions but in only small batches. Rory Jackson looks at how this company addresses that For on-highway vehicles, electrification is now seen as the way to go, but the future for electrified off-highway ones such as construction dozers, mining trucks and so on is less clear.

Autocraft takes us through its battery repair process

Autocraft EV Solutions now offers its highly automated and guided Revive battery repair and remanufacture system in service in both static and mobile versions (writes Peter Donaldson). We recently took the chance to discuss the system with Dr Sara Ridley, engineering & quality director of Autocraft Solutions Group, who has seen it through its development and early deployment. Dr Ridley explained what happens when a dealer needs a replacement for a battery in a customer’s car. “They log on to their web portal, which patches them through to ours. They tell us which battery they have a problem with, and we dispatch a replacement with all the packaging and paperwork they need,” she says.

Moulding method for pack covers

Materials firm Sabic has successfully moulded an EV battery pack top cover using low-pressure injection moulding (writes Nick Flaherty). The trial of the process is part of Sabic’s Bluehero initiative to show the manufacturability of large EV battery components using thermoplastic injection moulding. This specific form of...

Busbars and interconnects

Large EV battery packs can contain thousands of cells that have to be connected to form modules and packs, then connected via busbars to other driveline components such as inverters and DC-DC converters to make robust and reliable connections quickly and efficiently in confined spaces while keeping costs down. That has made...
