Overview
BQ40Z50-DEVICE-FW is a firmware-only release that can be flashed onto any existing BQ40Z50 hardware ( such as the BQ40Z50, BQ40Z50-R1, BQ40Z50-R2, … device ). The firmware incorporates the patented Impedance Track™ technology to create a pack-based solution that provides a rich array of features for gas gauging, protection, and authentication for 1-series, 2-series, 3-series, and 4-series cell Li-ion and Li-polymer battery packs.
Using its integrated high-performance analog peripherals, the BQ40Z50-DEVICE-FW firmware measures and maintains an accurate record of available capacity, voltage, current, temperature, and other critical parameters in Li-ion or Li-polymer batteries and reports this information to the system host controller over an SMBus v1.1 compatible interface. SHA-1 authentication, with secure memory for authentication keys, enables identification of genuine battery packs.
Features
The BQ40Z50-DEVICE-FW firmware is usable on any previous version of the BQ40Z50 hardware

Battery Management Studio (bqStudio) Documentation
Battery Management Studio (bqStudio) offers a full suite of robust tools to assist with the process of evaluating, designing with, configuring, testing, or otherwise utilizing TI Battery management products. This includes features that provide full access to registers and data memory including support for real-time watching, graphing, and logging, an easy interface to send commands, direct low-level communication and I/O, as well as automated and guided support for configuration, calibration, performing a learning cycle, and generating useful files for taking the device to production.
Older products such as bq20xxx and bq30xxx are not supported in bqStudio. Download the specific evaluation software from the appropriate product page.
Requires: EV2400 or MKST-3P-ALT-EV2300
SDK, API, and Programmer installer

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.
Overview
Several TI Fuel Gauge products support authentication for anti-counterfeit protection of battery packs. The selection of the battery authentication scheme between SHA and ECC is left to the user to decide. bqKeyPackager is provided to package the key, and bqKeyProgrammer is provided to program the key onto the selected gauge. The purpose of these two standalone tools is to allow an OEM to encrypt authentication keys in a file and send to a packmaker. The packmaker can then use this file as the data source for bqKeyProgrammer to program the key(s) into a gauge. The key will not be visible to the packmaker.
Features
Supports multiple TI gauge devices that support authentication
Supports SHA1, SHA256, and ECC key packaging depending on the device
Keeps key hidden from packmaker for additional security in the manufacturing process
Requires EV2300, EV2400 or MKST-3P-ALT-EV2300
