Sorry, but what is load balancing, and why would I want it?
Load balancing and load management is the ability for two or more chargers to communicate to each other to prioritize charging and to limit the charging load/current to meet the limitations that the building wiring might have. Here's an example;
You run a 50 amp circuit to your garage. One circuit, 50 amps total. You have one EVSE and your Bolt uses 32 amps to charge.
The wife comes home, she says she wants a Bolt and you roll like a log and buy her one.
You buy a second EVSE, and you wire it to the same 50 amp circuit you installed by simply adding the charger directly or by adding a second NEMA outlet. Two outlets, both capable of 50 amps but you have a total of 50 amps total to play with. This, is not a code violation btw, in case someone was about to chime in with that rubberish.
If you have two EVSE's that load manage, you could tell them to split the power between them, or you could tell it to charge car #1 ASAP with 32 amps and give 8 amps to car #2 until car #1 is charged at which point give everything to car #2. You could split it 50/50. Both get 20 amps for a total of 40 amps (taking into account NFPA capacity limits), and when one finishes charging before the other, the remaining car gets all it can take.
That is load sharing/management. I installed 125 amps into my garage (wanted a Tesla) so I don't 'need' load balancing, but I still would like it if I could pull it off. Some EVSE's do it, most don't. Some do it on their commercial line, but not the residential line (ChargePoint).
