There is no money in DCFC. The numbers simply don't make sense, especially given the current state of DCFC standards. Using government grants for this is just wasting money. CCS/CHAdeMO at this stage should not be installed at all. Force SAE to come out with reasonable 400 amp standard that then nominally 150-200kW, depending on what voltage you want to state that at (we know it's really 135 kW) and then we can start talking about ROI.
Simply, in order to make money on an existing DCFC, it has to cost a tremendous amount of money per kWh and the utilization rate has to be high enough that people are likely frustrated to use that charging network, as there can't be many idle, non-charging stations. Right now, the Tesla Superchargers are often far under-utilized, with many, many hours a day where there is zero charging or 1 vehicle charging. On a 6 or 8 plug station, utilization rates are likely under 5% on a daily basis.
