agree, for the most part, but you at missing the point that it all depends what we are talking about.

If it is level 1 charging then it takes HOURS ( can't even get from empty to full on a decent EV even if it is plugged in all night) and all your guys will definitely be using it at the same time but it uses about as much power as a refrigerator. Are your worried that your neighbors fridge might be working at the same time as yours?

If it is a level 2 charger then it takes hours (it is done before morning) but it uses about as much power as having an electric oven on.


but if it is fast charging like the OP originally mentioned the first thing to realise is that power consumption will change depending on how full the battery is. If it is empty it will draw the most power and fill the battery fast but as the battery fills it will slow down and drain less electricity, that is why the numbers tend to be how long it takes to go from 10% (considered empty) to 80% (full enough not to be wasting your time waiting for it to get fuller)

BMW i3’s -- 80 % -- 20 minutes
LEAF’s -- 80% --30 minutes
Miev --80% -- 30 minutes
Tesla -- 80% -- 40 minutes

so these will be a big drain on the power utility possibly in the first 1/2 hour of charging but 2+ hours is a long time and the guy that plugged in his car at 5 won't be much of an issue by the time the other neighbor plugs in his car at 5:30 and almost a none issue when the other neighbor plugs his in at 6:00 and done by the time the guy in the back plugs his in at 7:00.
