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.

Features
BQ27Z846-FW is a firmware-only release that can be flashed onto any existing BQ27Z846 hardware. The firmware incorporates the patented Dynamic Z Track™ technology to create a pack-based solution that provides a rich array of features for gas gauging, protection, and authentication for 1-series cell Li-ion and Li-polymer battery packs
Using its integrated high-performance analog peripherals, the BQ27Z846-FW firmware measures and maintains an accurate record of available capacity, voltage, current, temperature, and other critical parameters in Li-ion batteries and reports this information to the system host controller over an I2C compatible interface. SHA-1, SHA-256, and ECC authentication, with secure memory for authentication keys, enables identification of genuine battery packs.
