The Texas Instruments BQ27Z561-R2 Impedance Track™ gas gauge solution is a highly integrated, accurate 1-series cell gas gauge with a flash programmable custom reduced instruction-set CPU (RISC) and SHA-256 authentication for Li-ion and Li-polymer battery packs. The 1-series cell capability includes parallel cells for increased capacity.
The BQ27Z561-R2 gas gauge communicates through I2C-compatible and HDQ one-wire interfaces and includes several key features that can help facilitate accurate gas gauging applications. Integrated temperature sense functions (internal and external options) enable system and battery temperature measurements.
The integrated SHA-256 functionality helps enable secure identification between systems and packs. The interrupt and BTP functions facilitate the BQ27Z561-R2 device to inform the system when a specific state-of-charge (SOC), voltage, or temperature condition occurs. The low-voltage operation enables the system to continue monitoring the battery even in deeply discharged conditions. During low-activity situations, set the device to the low power coulomb counting (CC) mode, which enables the device to continue coulomb counting, while reducing operating current significantly.

Description:
BQ-BATTERY-PROGRAMMER-SW software development kit (SDK) is a collection of robust software command line tools that assist with the process of programming, testing, or assembling packs that use TI Battery management products. The executables in this software work with the MKST-3P-ALT-EV2300 MKS Technology alternative for EV2300 communications transceiver. The executables work with a single station but can be extended to multiple stations by using additional software and GUI from MKS Technology Inc. . Support for multiple stations is not included in this software.
There are multiple executables in the download, usually one per family of products. Older products such as BQ20xxx and BQ30xxx are also supported. Examples using the C++ programming language API and Python® programming language are provided for custom development.
Requirements:
Features:
Getting started:
1. Download the software
2. Run the installer
3. The executables, C API and Python API files can be found in the install location
4. Run the command line executable without arguments to get usage help. Refer to Readme.txt in the install folder for more information and how to get help using the command line.

General notes
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. SingleCellbqProduction supports 1 station from a single computer and has inbuilt capability to maintain log files for the processed printed circuits boards. The bqMTester hardware is incompatible with some single cell gauges.
Operating systems: Windows XP, Windows 7, Windows 10
Requires: MKST-3P-ALT-EV2300 (MKS-SAI-001), Precision voltage and current source/sink for calibration.
