Charging protocols for hotel installing charger (any ideas?) The Hilton Austin is nice enough to be installing a J1772 70A charger. What should I tell them to do with the spot? I told them to paint the ground of the parking spot 'EV only' and have signs saying spot is for pure EVs, not plug-in hybrids. They should then put maybe a 110V and a NEMA 14-50 outlet in the two spots next to it for people with mobile chargers. They said that if demand increases enough, they would install another charger in the valet area (the new one is going in the parking garage). Thanks.
