bq20z655EVM and bq34z651EVM SBS 1.1 Impedance
Track Technology-Enabled Evaluation Module
This evaluation module (EVM) is a complete evaluation system for the bq20z655/bq29412 and
bq34z651/bq29412 battery management system. The EVM includes one bq20z655/bq29412 or
bq34z651/bq29412 circuit module and a link to Windows
bq34z651/bq29412 battery management system. The EVM includes one bq20z655/bq29412 or
bq34z651/bq29412 circuit module and a link to Windows
®
-based PC software. The circuit module includes
one bq20z655 or bq34z651 integrated circuit (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 over-current 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 or EV2400 interface board and software, the user can read the bq20z655 or bq34z651 data
registers, program the chipset for different pack configurations, log cycling data for further evaluation, and
evaluate the overall functionality of the solution under different charge and discharge conditions.
