So you CANNOT balance a pack at an L2 or an L3 unless its a station that is free and always on (needs no card, smartphone access, etc.) Now L3's that are free and only require a button to be pushed will also not balance the pack.
To balance a pack, it requires multiple power on cycles.
I don't know about later models, but both 2011 and 2015 will hold L2 (or L1) charging active until charge is complete so cell balancing will function on public L2 EVSEs. Charging current will cycle down to very low levels during balancing so public charging cost could be high if charges are based on time instead of energy. I think the balancing shunts are also active during DCQC so some cell balancing happens, but car will not get a full charge when using DCQC.
