I had the same question when I was a newb. My volt advisor assured me that level 2 charging will not have any adverse affect on the volt battery. But I believe (I might be wrong) that if Chevy had installed a 6.6kw charger instead of a 3.3 one, we might see battery degradation as leafs have seen. There's a reason why nissans give you a warning about the using the DC fast carge too much. Plus there has been a Tesla owner who has apparently over-supercharged his Tesla and it now forces a slower than normal supercharge, which he got all bent out of shape about in the Tesla forum, causing other Tesla members to question whether it was true as their beloved vehicle was getting dissed in the process.
Part of the reason for this battery longevity is that GM designed it to stop charging before the battery is competely full, and prevents you from using hte battery before it is completely empty, so a full charge andfull drain is really only a partial fill and drain. Batteries start to degrade at the extreme Speeds (fully charged or fully empty) plus the temperature management system goes a long, long way in keeping the battery in tip to' shape. The OP probably won't see this in Cali but when the car is really cold and unplugged for awhile, the ICE will start suddentyl upon powering up, and propel the car on generator only until the batteries warm up enough to where it is safe to discharge or charge the battery. It has it's own self-preservation mode.
