I did something similar to this, only using 240VAC rather than 120VAC. I
have both NEMA 14-50 and J1772 power inputs to the charger. I used this
DPST relay with 240VAC coil to switch between them:

This relay is a good choice for this application. One important feature
is that its normally-closed contacts have the same voltage-current
rating as the normally-open contacts. This is not true for many relays
(read the fine print!)
Good point, the relay I was considering was only rated at 30A for the NO
contacts, and only 3A for the NC contacts! Back to digikey....
