Battery pack electronics

by Hfuy on Mon Nov 15, 2010 5:38 pm

Has anyone had any experience implementing the various lithium-ion protection and charge estimation ICs that are out there? I've looked at TI's BQ series and Maxim's DS series, and they all seem to be reliant on, or at least intended to communicate with, significant electronics in the host system. What I'm after is something that I can implement as a gas gauge (with LEDs, or whatever) and protection circuit (in order to prevent the whole thing from catching fire or exploding if mistreated).

There are a few ways to approach this, but I'm after one which doesn't cause me to need to retrofit every device that'll be powered by the battery with lots of onboard intelligence.
