The grid upgrade can cost millions for a DC fast charging station.
The inverter to make the DC power can cost 100,000.
Why not skip all this and have a diesel engine coupled to a 400V DC generator, thereby skipping the inverter and grid upgrade?
I think this would be cheaper, and lower capex and operational costs. Not to mention, most streets have natural gas lines which could power the diesel engines with a cheap and clean burning fuel. Natural Gas is very cheap around 4c/kwh. A 20% efficient generator, would yield 16c/kwh.
Making your own power has a really high cost per kWh. You can’t beat the price of big power. A diesel is such short sighted thinking. It has happened for temporary reasons.
Just run the power lines as once it’s run the line will charge cars for a half century. The amortized cost is fuck all.
Mobile generators will be the kind of festivals and other events where a lot of cars go to remote places like festivals in the middle of nowhere. That captive audience will pay a steep price.
