IIRC they use PKI with your keypair bound to your account. So if you own a Tesla and hack it you can pretend another car is that Tesla. You can also hack someone else's car but then they'd have to pay for your charging and that'd probably be stealing or something like that.
If I had an electric car I'd try to figure out the auth protocol, surely software-wise it's possible to pretend that a Tesla is plugged in (worst case is that there's a cryptographically secure key exchange, and someone would have to extract the key from a Tesla).
Hah, an adapter that pretends to be a Tesla that plugs between the supercharger and your car, that would fit in a cyberpunk-ish 2021.
