-based PC software.
The circuit module includes one bq3055 IC, one bq29440 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-series, 3-series, 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, users can read the bq3055 data registers,
program the chipset for different pack configurations, log cycling data for further evaluation, and evaluate
the overall functionality of the bq3055/bq29440 solution under different charge and discharge conditions.
