So, is that an average cost of $3.25 per gallon of amps? Or $3.25 per litre of voltage?
$3.25 for ~30 KWh (charging rate for these things is about 65 KW).
So, 330 of the things in Estonia, they each support one vehicle at a time...~8000 EV's per day supported by the entire network, assuming that every one of them is being used 24/7?
Hmm, wonder how far your average EV goes on 30 KWh....
You seem to lack experience with electric vehicles, so let me enlighten you. I have driven a Leaf 12 000 miles the last year and know a thing or two:
Most EV owners will use these stations very rarely. Charging is usually done at night or at work when the vehicle is parked anyway. Any ordinary electrical outlet will supply enough energy in 8 hours for a lot of driving. Assuming 230V/10A 8 hours will give 230*10*8*0.9 ~= 16 kWh of energy (90 % charging efficiency) This is enough for at least 80 km, possibly more than 100 km, depending on roads and driving style. Most places, at least in my country, 16A is available most places which would add 60 % to the above figures.
Quick charging is only ever used if you want to go much farther than usual, which should happen rarely. Few people will buy an EV if the daily commute cannot be done on a single charge, possibly charging in both ends. Luckily, most people commute much shorter than the range of current EVs and with this quick charger network, they can cover longer distances when needed, albeit spending some time charging. Thus this network can service a lot more than 8000 cars. It will be interesting to see if this will result in mass adoption of EVs in Estonia. The infrastructure is certainly there, but I fear EVs are still a tad too expensive for a population that isn't too rich generally.
