Overview

The bq78z100EVM-532 evaluation module (EVM) is a complete evaluation system for the bq78z100 or bq294502 battery management system. The EVM includes one bq78z100 and bq294502 circuit module and a link to Windows™ based PC software. The circuit module includes one bq78z100  integrated circuit (IC), one bq294502 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 1- or 2-series cell Li-ion or Li-polymer battery packs. The circuit module connects directly across the cells in a battery. With the EV2400 interface board and software, the user can read the bq78z100 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 using HDQ communication protocol.
