Agreed. Demand charges are deal killers for affordable fast-charging though. Maybe there is a sweet spot just below the demand charge threshold, maybe 30-40kW "urban" fast chargers could fill this niche affordably.That's certainly true, but we don't have the pricing structure standardized and reasonable.
I've checked out a few CCS/SAE charging stations in Virginia and the DC Metro area, and it seems to me that if you have to resort to using these on a regular basis, you've basically blown the EV cost benefits to ****.
240 volt, 32 amp, 7.5 kW charging at home seems to be the sweet spot.
The pricing on the East Coast seems to be standardizing around $0.35/kWh, give or take. That includes Virginia and DC Metro. That's pricey, but for highway chargers, I'm happy to pay it. Especially if my next EV can charge around 100kW.
