The bq28z610 EVM evaluation module (EVM) is a complete evaluation system for the bq28z610 or bq294502 battery management system. The EVM includes one bq28z610 and bq294502 circuit module and a link to Windows™ based PC software. The circuit module includes one bq28z610 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 Ev2300 or EV2400 interface board and software, the user can read the bq28z610 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 I2C communication protocol.
