APPLICATION NOTE 131
Lithium-Ion Cell Fuel Gauging with Maxim Battery Monitor ICs


Abstract: This application note describes to the user how to improve remaining capacity estimation for Li-ion
battery packs beyond the accuracy level of using a coulomb counter alone. It outlines a methodology using
Maxim battery monitor ICs along with fuel gauging software that comprehends the effects of battery cell age,
as well as the charge discharge rates of the application, on the remaining capacity of a Li-ion battery pack. The
result is a low-cost, but highly acc
