Dow launches conformal coating for harsh environments

Dow has unveiled a new conformal coating it calls Dowsil CC-2588. It is an abrasion-resistant silicone-based material that protects PCBs and electronic components against high humidity and corrosion. The coating is virtually odourless and cures at room temperature. It can be sprayed on in a single pass and dries to a film thickness of 50-200 […]

Tesla Octovalve analysis

It’s not often that we get the opportunity to dig into the details of an important EV subsystem from the point of view of an independent engineering team, but that is what Cory Steuben of Munro & Associates provided at the recent Battery Show and EV Tech online event (writes Peter Donaldson). The subsystem was the Tesla Model Y’s heat pump, in particular...

Battery Cooling

As liquid-based cooling for EV batteries becomes the technology of choice, Peter Donaldson explains the system options now available. Although there are other options for cooling EV batteries than using a liquid, it is rapidly taking over from forced-air cooling, as energy and power densities increase. It is emerging as the dominant technology...
