AC uses 3kw’s and many homes have two, so during a heat wave, it seems like those transformers should already be severely overloaded.
A clear saving grace of EVs is that there is a lot of hours during the evening to charge a car (and most aren’t going from zero). Coordination on when to start and trickle charging across the whole evening seems like a much cheaper way to stretch the grid’s capacity than mass upgrades.
- _ea1k 4y agoI agree. His wording is interesting though: "it is not unusual" - Maybe he means some case with exceptionally small houses in a climate where AC is not needed and not installed and noone uses electric heat? Coordination is an in interesting aspect. The nice thing is that these cars tend to have internet connections and the ability to remotely control charging. In my area, we are already seeing utilities experiment with offering incentives to allow remote control to improve load management. The technical solutions in many cases no longer require additional hardware.
