bq40z80EVM Li-Ion Battery Pack Manager Evaluation
This evaluation module (EVM) is a complete evaluation system for the bq40z80 battery management
system. The EVM includes one bq40z80, two bq771807 secondary protectors, and a link to Microsoft
Windows
based PC software. The circuit module includes one bq40z80 integrated circuit (IC), two
®
bq771807 secondary protectors, 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-, 4-, 5-, 6-, or 7-series cell Li-ion or Li-polymer battery
packs. The circuit module connects directly across the cells in a battery. The bq40z80EVM can use the
on-board EV2400 or an external EV2400 interface board and software to read the bq40z80 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.
