It doesn’t need to be that smart. Just spreading the charging time across the full evening always would reduce load significantly without transformer level coordination or smart transformers. Kick off charging when grid capacity is lower than a certain threshold, and trickle into EVs based on how much charge is needed. EVs already let you specify when you want to leave in morning, so it’s a small extension to that.
