Don't know about the Prius BMS, but the Honda Insight limits charge to between 20% and 80% of capacity.

I've been looking at adding a second battery pack in parallel on mine. (Lots of mountains hereabouts, and it irritates me when regen has the pack completely charged when I'm only halfway down.) Some people have apparently done this, and it seems to work ok.
