At home I use my old AV EVSE from my LEAF days. Even at only 30A I can almost always manage to fit my charging within my off-peak TOU rate plan window. I rarely use my UMC. My (probably) dumb question is, during a range charge using the AV EVSE, can the car balance the battery if it wants to, or do I need a a Tesla charger for that? I know this is handled by the battery management system in the car, but I wasn't sure if there was some special protocol necessary between the charger & EVSE to facilitate this.

The Model S communicates using the J1772 protocols for all A/C charging, including with the UMC and HPWC - it just has a different connector geometry. That being the case, I don't see how there would be a problem with the balancing.

How do you define "a lot of time"? My range charges on my AV EVSE @ 30 A don't seem to take all that long. Sure, the last few miles take half an hour, but I suspect that once the rate on a HPWC drops to 30 A, the time to completion is the same for both EVSE's.
