Enabled Battery Management Solution EVM
The
bq20z45EVM-001
evaluation
module
(EVM)
is
a
complete
evaluation
system
for
the
bq20z45/bq29412 battery management system. The EVM includes one bq20z45/bq29412 circuit module,
a current sense resistor, two thermistors, and a link to Windows
a current sense resistor, two thermistors, and a link to Windows
™
-based PC software. The circuit module
includes one bq20z45 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, overdischarge, 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 bq20z45 data registers, program the chipset
for different pack configurations, log cycling data for further evaluation, and evaluate the overall
functionality of the bq20z45/bq29412 solution under different charge and discharge conditions
