1.1 Introduction

The EVM includes one BQ41Z90 and BQ77216 circuit module and a link to Microsoft®Windows® based PC software. The circuit module includes one BQ41Z90 integrated circuit, one BQ77216, 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 3- to 16-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 BQ41Z90 data registers, program the chipset for different pack configurations, log cycling data for further evaluation, and evaluate the overall functionality of the design under different charge and discharge conditions.
