bq20z60EVM-001 SBS 1.1 Impedance Track™ Technology
Enabled Battery Management Solution Evaluation Module
This evaluation module (EVM) is a complete evaluation system for the bq20z60/bq29330/bq29412 battery
management system. The EVM includes one bq20z60/bq29330/bq29412 circuit module, a current sense
resistor, two thermistors, and Windows™-based PC software. The circuit module includes one bq20z60
integrated circuit (IC), one bq29330 IC, one bq29412 IC, and all other onboard components necessary to
monitor and predict capacity, perform cell balancing, monitor critical parameters, protect the cells from
overcharge, over discharge, short circuit, and overcurrent in 2-, 3- or 4-series cell Li-ion or Li-polymer
battery packs. The circuit module connects directly across the cells in a battery. With the EV2300 interface
board and software, the user can read the bq20z60 data registers, program the chipset for different pack
configurations, log cycling data for further evaluation, and evaluate the overall functionality of the
bq20z60/bq29330/bq29412 solution under different charge and discharge conditions.
