This evaluation module (EVM) is a complete evaluation system for the bq20z95/bq29412 battery management system. The EVM includes one bq20z95/bq29412 circuit module, an EV2300 PC interface board for gas gauge interface, a PC USB cable, and Windows™-based PC software.
The circuit module includes one bq20z95 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 circuit module connects directly across the cells in a battery.
With the EV2300 interface board and software, the user can read the bq20z95 data registers, program the chipset for different pack configurations, log cycling data for further evaluation, and evaluate the overall functionality of the bq20z95/bq29412 solution under different charge and discharge conditions.
The EV2300 is a USB-based interface board for a PC that can be used to evaluate battery fuel gauge circuits designed with Texas Instruments' ICs. The EV2300 has connections on it for a USB cable and also accepts inputs from a battery fuel gauge circuit's communication port (SMBus or HDQ). By running the appropriate PC software for the corresponging fuel gauge IC, the EV2300 interface board allows the user to evaluate the battery fuel gauge circuit.
