Does anyone do home maintenance/repairs on EVs and Hybrids?

[fatjon]

Mine needs a brake check about every 50k (rarely use them other than to clean the disks up) and maybe some transmission oil every 100k. I reckon I can handle it.
With dealer fault diagnosis like “the battery is going flat because you left an iphone cable plugged in”, or “we charged the 12v battery all night and it’s reading 11.99 volts so it’s perfect…”

I think I’d rather do it myself.

Ah the internal resistance of skin wasnt doing you any favours then which is why over 50V is normally an issue for humans.

Which is directly related to voltage (assuming your resistance is the same). Simple ohms law.

How did you manage to get a bad burn from just 5v?

That's not an electric shock though. I always remove my ring when around power of all sorts. Electric shock is skin resistance & most humans with dry skin will be 1000's of Ohms hence no electric hock hazard.

And for those PHers who enjoy a bit chronographic wrist time, take your watch off. The large area metal back and a sweaty wrist make for lower resistance...

Yes, watches and rings do have a significant level of sweat underneath.

Fitted a tow bar to our Ioniq 5 without any drama. Followed the Hyundai process to isolate the traction battery and 12V, then it was all regular car processes there on.

Had our BMW i3 for 5 years, not much has needed doing to it, with MOT get brake fluid changed every 2 years, at home have fixed window washer and heated seat needed fixing thats it

I work in the larger end of the motor industry, and last week one of our development engineers got a bit shock 48v but God knows what current. He had followed all the correct procedures, and touch something that should have been free of charge and wasn't.

Just invest in a pair of insulated gloves.

with elecric cars you have to be VERY careful with electric cars, especially when a circuit says a low voltage, it could indeed be a low voltage across these two ponts but with respect to earth it may be a lot higher.

think on it as like a battery it may be 24v but it could be 800v between the battery and earth.

Id touch a 5v supply put my fingers across it or even hand to hand as 5v will not drive enough current through you. there would have been other factors involved.

that explains it - you got burned from the effects of that short through your ring. not from the passage ofcurrent through you.

People will get used to them though. With ICE cars you have things like poisonous gases from the exhaust, diesel injectors at 20k PSI to blast diesel into your body, highly flammable liquids and vapours to accidentally set on fire, spark plug voltages in the kV range, and plenty of already very hot things to burn yourself on. Most of those existing dangers that people are used to working around go away - but some are replaced by new and different things to injure yourself with.
