Are those charging poles different power to what a genny puts out???
Either single phase at a much higher rate than a genny, roughly 7 kw continuous, 3 phase at around 22kw and fast DC at 150kwand ultra fast DC at 200kw. It is expected, when the truck EV charging rolls out, around 500kwDC to 800kwDC, or the battery swap method that takes half the time to add 400km of electric fuel to the time taken to add 400kms of diesel.
Generally, the faster the charge, the more expensive, the 7kw is around 25c kwh, the 3 phase 22kw around 33c kwh and the rapid and ultra rapid DC at around 62c kwh, so around $240 to recharge a 400kwh battery and around 2 hrs. So you would only use the ultra rapid DC chargers is you were in a hurry. The cost for the 800kw truck DC charging is as yet an unknown, but estimation are around $1 kwh to $1.20 kwh and this will be via battery to battery charging, the donor battery will most likely be a tired truck battery rebuilt to a higher voltage and recharged via solar or cheap power during the day when the grid actually pays people to take excess grid supply to store in batteries. The aim is to decentralise the load points so wind and solar farms don't have to push the power all the way to the city where it would normally be used, it can be stored in more remote areas and accessed as needed.
