TIDA-00050

This reference design is designed for the bq20z65/bq29412 battery management system. It includes one bq20z65/bq29412 circuit module and a link to Windows™-based PC software. The circuit module design includes one bq20z65 integrated circuit (IC), one bq29412 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 2-, 3- or 4-series cell Li-ion or Li-polymer battery packs. The reference design connects directly across the cells in a battery. With the EV2400 interface board and software, the user can read the bq20z65 data registers, program the chipset for different pack configurations, log cycling data for further evaluation and evaluate the overall functionality of bq20z65/bq29412 under different charge and discharge conditions.
