Fast charging will be perfectly profitable in the longer term. There just isn't a large enough established base of EVs to create enough demand yet. But once there is, there will be plenty of customers willing to pay a premium for the fastest, best-located chargers with the best amenities and services on site.
Fast charger operators can make significantly higher margins on reselling electricity than anyone is making on gasoline.
Demand charges are an issue when demand is limited and spiky, but this will be alleviated through increased scale. More customers charging results in a smoother, more predictable demand curve. On-site battery storage is another solution.
It isn't the standard now. All other manufacturers have switched to CCS Type 1 Combo. Tesla is the last holdout.
Tesla sells J1772 chargers and they will sell a CCS adapter. The next step is to put CCS plugs on the chargers and then CCS inlets on the cars.
“How do we democratize access to electric vehicles? That’s a very important part of our strategy,” Mark Fields, who joined Hertz as interim chief executive officer earlier this month, said in an interview. “Tesla is the only manufacturer that can produce EVs at scale.”
A standard that no one else uses is not much of a standard. All other manufacturers have switched to CCS Type 1 Combo. Eventually Tesla will switch too.
