Abstract

This evaluation module (EVM) is a complete evaluation system for the bq40z50 or bq296000 battery management system. The EVM includes one bq40z50 and bq296000 circuit module and a link to Microsoft®Windows® based PC software. The circuit module includes one bq40z50 integrated circuit (IC), one bq296000 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 1-, 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 bq40z50 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.
