See my post above. A GM dealer that is servicing Bolts that needs to be able to charge several a day fully within a reasonable time frame, and needs a DC charging station on the premises to qualify to sell/service Bolts.
So... an idiotic dealership requirement justifies this lunacy?
The best way to charge more EVs is to have more plugs. That's multiple L2's overnight. No reason for a low power expensive DC charger at a dealership. If they need a DC charger, install the fastest one... drop the $40-60k it costs per plug. Install 2-4 plugs. Can't afford the $200k? Simple, don't install DC charging. Makes much more sense to install 10-20 J1772 plugs for the $15k.
