The fast charger is the expensive part, the dispenser is not nearly so. Just like a gas station, dispensers to chargers are many-one. I was being a bit glib when I said the dispenser is a fancy switch (esp if the lines are cooled) but only just a bit.

I see a report that has Tesla’s cost as 43k per installed dispenser. That is a fully load cost, not the marginal cost of dispenser but it is good enough.

Looking at listings for gas stations for sale (with a convenience store but no auto repair), I see about 150-300k per dispenser. That isn’t exactly apples to apples but suffice to say it isn’t exactly cheap and much closer to representing the cost than the cost of a pump (which is I assume cheaper than a dispenser).

At least the Tesla implementation of their latest stuff, dispenser to faster charger ratio is 1:1. Their older design would gang 2 dispensers to a single 150kW combined charge rate, but new ones are 250kW per dispenser for each port simultaneously.
