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.
