Some EV's charge with AC chargers (the car has an onboard AC to DC convertor) and some with DC chargers (no onboard convertor necessary). The Porsche Taycan is capable of charging with both. But what I dont get is that DC is better and faster than AC. So yeah, still a muppet for having a license plate bragging about AC charging!
Going by the sentiment lately, AC could mean other things as well and insistence of 'Forever' adds high probability to that word as well but lets not go there..
