Measured by revenue less cost of operations (opex) and cost to carry capex (interest or opportunity cost) is there any proof that non-Tesla DC fast chargers are making any money from charging? Breaking even?
If they are, why aren’t more companies getting into installing chargers for profit?
If they aren’t, how do we ever get to sustainable, operational infrastructure that meets consumer expectations like the gas stations they’re used to?
to lower capex costs, i think we should run these DC charging stations from diesel or natural gas generators.
We can thereby skip the expensive grid and transformer upgrades ?
It’s been done with batteries. The idea is that they take energy from the grid at a low cheap rate (sometimes from solar panels) and then when a car comes by, discharge rapidly into it. There are multiple vendors with battery backed DCFC.
