Do electric cars use the main battery to power electronics through AC outlet?
I know that on gas powered cars the alternator is used to power electronics, but am wondering if electric vehicles use the main battery.
The reason I'm asking is because I'm thinking of getting a electric cargo van and put a solar panel on the roof to charge the main battery so I could power a gaming laptop for long periods of time.
I wanted to go "off the grid" and still game on my laptop, would the main battery power my laptop?
Sorry if this is a stupid question, I don't know much about cars.
