Be very careful who you trust on these issues. A typical level 2 charger is 30 amps by 220 VDC. That's 6600 watts. That's the equivalent of four standard 120 VDC, 15 amp household circuits. If two people using level 2 chargers would blow out a neighborhood transformer, there are significant design flaws with the local infrastructure, and the utility company has set themselves up for failure.
I'm not saying the increase in the number of EVs charging at night won't cause any problems at all, but utilities are heavily regulated. They have to provide reasons for rate increases, and this looks like a honey pot for them. Expect them to shout about it at the top of their lungs.
