Thought on charging % each day?

Batteries are usually top balanced, meaning balancing is done near 100% SoC. Less common, batteries are bottom balanced near the lower end of their useful SoC. There's also active balancing which I suppose could be done at any SoC, but I haven't heard of this being implemented in EVs.

The balance method isn't discussed anywhere that I've found yet, but my hunch is the Bolt uses top balancing, which means it wouldn't balance when hilltop reserve is used. That said, it probably doesn't make that big of a difference, and occasional full charges to balance would correct any accumulated imbalances.

I'd be curious to learn how the Bolt does balancing, but in everyday use, it probably doesn't matter much if we are charging to full or not.
