The Texas Instruments bq27320 system-side li-ion battery fuel gauge is a microcontroller peripheral that provides fuel gauging for single-cell li-ion battery packs. The device requires minimal system microcontroller firmware development. The bq27320 uses the compensated end-of-discharge voltage gas gauging algorithm for fuel gauging, and provides information such as remaining battery capacity, state-of-charge, run-time to empty, battery voltage, temperature and state of heatlh.
External temperature thermistor NOT included
Production Software for Single Cell Battery Fuel (Gas) Gauges
Overview
SingleCellbqProduction offers a full suite of robust tools to assist with the process of configuring, calibrating, manufacturing and tracking printed circuit boards utilizing TI Battery Battery management products. This includes features that allow writing a golden image followed by different types of calibration to provide desired levels of accuracy and finally validating limits for calibration parameters to spike out any inconsistencies in material. SingleCellbqProduction offers three(3) levels of access to allow strict control over the manufacturing process with the assembly line operator only having access to the "Start" button. In addition, SingleCellbqProduction supports upto 12 parallel stations from a single computer and has inbuilt capability to maintain log files for the processed printed circuits boards. Requires EV2300. The bqMTester hardware is incompatible with some single cell gauges.
