Double-sided ceramic power module for drive inverters

Engineers in Germany have developed a double-sided ceramic power semiconductor module for more efficient cooling of silicon carbide (SiC) power devices in e-mobility designs (writes Nick Flaherty). The ceramic module developed in the FuCera project dramatically cuts the size of drive inverters by providing more efficient cooling and allows vertical interconnection within the ceramic substrate […]

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...
