Not to steal thunder from the OP site but WeberAuto has amazing YouTube videos on a LOT of EVs, systems, transaxles, motors, gearboxes, and everything.
Are you looking into fixing the drivetrain or the "car stuff" around that? I'd rather not fiddle around with the 400 V system of my EV, but I think most of the other things are still the same.
Any similar course for EVs would start with high-voltage safety. If you're doing any high-voltage work, you'd start by physically isolating the high-voltage battery from the rest of the car by pulling the main isolation fuse. Then, you'd check everything with a voltage detector just to be absolutely sure. And you'd wear electrical insulating gloves whenever touching anything that could potentially be live.
All high-voltage components in your EV are well protected and clearly marked in bright orange: there isn't much danger of accidentally running in to them when working on anything else.
There's an aura of mystery around EVs (e.g. people assume they're all some self-driving black box magic), so it may be useful to teach how they work even if people aren't going to do DIY repairs.

The professor that teaches it (John Kelly) is amazing and very well experienced in the industry: https://www.weber.edu/automotive/j_kelly.html
