I hooked up my new Plugshare charger with WiFi. I noticed that every 2 hours it does a quick charge again. Would this be just topping up the battery?

From what I know, the Volt will constantly be conditioning the traction battery between charges. If you're near the car during those times, you'll hear your Volt's coolant pumps and possibly radiator fans running.

I do not believe that it charges the 12V battery during those times. Most EV's only do that when traction battery is engaged: When it's charging or being used.

What EVSE are you using? I've been looking for a good one that has WiFi and doesn't cost $500. (Edit: Oh, is that a Charge point EVSE. That's what the app looks like.)
If that's true, then why doesn't the 12V battery go flat if the 12V system is burning something like 100~200W all the time, to power the BMS?

Or do you 'believe' that all the BMS and control electronics are working at 400V?

Think about it! Pretty obvious it is topping up the 12V system.
If the HV battery is engaged during the conditioning, it is not long enough to charge the 12V battery. I've read many times about Volt's having dead 12V batteries while plugged in.
