bq34z100EVM Wide Range Impedance Track™ Enabled
Battery Fuel Gauge Solution
Tom Cosby
This evaluation module (EVM) is a complete evaluation system for the bq34z100 wide-range fuel gauge for
lithium ion, Nickel metal hydride (NiMH) and Nickel Cadmium (NiCd) chemistries when combined with an
EV2300 USB adapter and Microsoft
The circuit module includes one bq34z100 integrated circuit (IC) and all other components necessary to monitor
and predict capacity in one or more series cell Li-ion, Li-polymer, or LiFePO4 battery packs. The minimum
series cell count for PbA, NiMH, and NiCd chemistries must exceed 3.3-V stack voltage. The circuit module
connects directly across the battery stack. With the EV2300 interface adapter and software, it is possible to
read the bq34z100 data registers, program the chip for different pack configurations, log cycling data for further
evaluation, and evaluate the overall functionality of the bq34z100 solution under different charge and discharge
conditions.
