ROSS DCB-5 blender masters dense battery powders for EV production

Powder blenders don’t often steal the spotlight in EV engineering but the ROSS 5 cubic foot Double Cone Tumble Blender Model DCB-5 deserves a close look. Engineers tackling battery materials know the challenge of blending high density powders into uniform mixes. This machine steps up for small to mid scale processing with the toughness to […]

5 A battery simulator

Pickering Interfaces has developed a simulation card that supplies up to 8 V and 5 A on each of four channels for testing battery management systems at the desktop, writes Nick Flaherty. The PXIe card, which handles up to four channels, each with a 5 A source or sink, is small enough to sit on an engineer’s bench rather than in a 19 in rack.

Battery thermal barriers

New materials from carbon nanotubes to intumescent polymers are opening up innovative ways of providing thermal management in e-mobility battery packs, as Nick Flaherty finds out. From mica sheets to thermal gap fillers and aerogels, there are now more options than ever for managing heat flow through a battery pack and powertrain, and for mitigating the effects of thermal runaway.
