EV owners will set their cars to pause charging between 5 and 8PM to avoid the time of typical peak demand
We investigated and found that our peak demand was hot afternoons. Air-conditioning uses far more kWh than stoves because once the AC is running it’s left on until bed-time (or all night in some cases). Meanwhile, refrigerators run for a few minutes and stoves are turned off after an hour or so.
So perhaps any permission to draw current for EV charging should allow for the weather!
Sure. The peak can vary from season to season and place to place. A load management system would sort things automatically and is probably part of an ultimate solution. However, shorter term, ad hoc solutions for the first X% of plug-in vehicles can work and buys time to work out what is really needed for the building, to educate owners, build support and save up for what might be needed. While all this is happening, you don’t need to hold people back if you don’t let them pull too much current and avoid adding to a reasonable guesstimate of when the building peak would be.
