Do EVs have a battery isolator switch or similar, to allow welding?
I dunno the answer to this one steffo, but some other useless info for ya
I might be worng here, just some info I had during a convo over some beers
I think the likes of Tesla dont support utilising the power from the car for any other reason except powering the car. Some smarties apparently found a way to bypass this but Tesla have advised that will void the warranty etc on the batteries themselves. I heard the reason for this is it could deminish the life and capacity / distance of the batteries etc......ah, there ya go, quick googles

Funily enough however other leccy car vendors do allow and provide provisions for it, like Hyundai perhaps.
