bq20z70EVM-001 SBS 1.1 Impedance Track™Technology
Enabled Battery Management Solution Evaluation Module
This EVM is a complete evaluation system for the bq20z70/bq29330/bq29412 battery
management system. The EVM includes one bq20z70/bq29330/bq29412 circuit
module, a current sense resistor, two thermistors, an EV2300 PC interface board for
gas gauge interface, a PC USB cable, and Windows™-based PC software. The circuit
module includes one bq20z70 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 bq20z70 data registers, program the chipset
for different pack configurations, log cycling data for further evaluation, and evaluate
the overall functionality of the bq20z70/bq29330/bq29412 solution under different
charge and discharge conditions.
