So suppose we build a DCQC with more than 2 of chargers at 150kW or higher. We would use Schedule 26. Think https://www.plugshare.com/location/163287 or similar
Service fee of $110.51, Demand charge of $12.55/kW, $0.06556 per kWh
If one car per month charged 80kWh at 150kW, the total electric bill per car would be $1,998.25, at peak seasonal rates.
Ouch.
If one car per hour charged 80kWh at 150kW, and 5 cars maximum, the total electric bill per car would be $9.65. That's right, twelve cents per kWh, at peak seasonal rates. And one car per hour would be fairly light usage, probably never a wait for a charge, even on busy weekends.
Of course this is only part of the cost. Site costs, buying and eventually replacing the DCQC chargers, charger efficiency, maintenance, line painting, signage, security, credit card fees and probably things I didn't mention will all drive up the cost. And price would include profit.
