Just plug it in whenever you plug the car in to charge, and unplug it when you unplug the charging cable. That will also allow you to leave the car plugged in but not charging for as long as you like. It's what I use, except my Battery Tender JR is only 0.75 amp.
I've wondered if a trickle charger could be installed permanently, and wired to draw its supply power from the J1772 AC lines 1 & 2, whenever the car is charging from an EVSE. You'd need to fuse the charger leads where they connect to the AC lines 1&2; and you'd need a charger which accepts either 120 or 240v.
It's not something I'm going to do, but it seems like it could be done.
