The one case I know of involved an unregulated bad boy charger left on the pack unattended and forgotten. It's always a good idea to have some kind of upper bounds sanity check built into your charger controller. For example, if your battery is 250 amp hours and the charger has delivered 500 amp hours, stop charging and set an error condition, even if no other charging algorithm rules have been fulfilled.
