When I was working for the EV place in the 90s that was one of the things they considered. When on 3 phase power you could actually put power back into the grid. We literally ran the meter backwards. The idea was all these battery packs could be used to even out local power demand surges (it could also correct for power factor which was cool). I find it amusing that now, over 20 years later, people mention this as a new idea.
Currently the way they handle it is with power pricing and offering cheaper rates later in the evenings (say after 9pm) to get people to charge after the early evening peak. Is that sustainable when more people do it is hard to say. I think some of the home chargers are smart enough now that you can tell them what hours to charge between.
One of the things I have noticed is a lot of the talk about EVs and the advantages is based on there not being many around. For example the 20 minute charging time on the road doesn't seem so bad if the charger is available which, with few cars on the road, is likely. They never mention the wait if you're the third in line for the charger say!
