Making batteries idiot-proof ... questions
Bob Axtell email (remove spam text)
NOTHING is idiot-proof, as idiots are cunning and very resourceful,
MUCH more so than design engineers..
But I have discovered that building a 12V NiMH pack, and installing
a Maxim one-wire thermometer is about as good as it gets. You use the
thermometer to monitor both charging AND battery failure, in that a bad
cell heats up when being charged AND being used. You use a simple
PIC to monitor battery voltage, so if it overheats before topping off (15V),
the battery pack is defective.
Don't fiddle with NiCADs, the technology is considered by MOST US states to
be too toxic to be sold anymore.
