Overview

BQ40Z50 family of gauges firmware is a firmware-only release that can be flashed onto any existing BQ40Z50 hardware (such as the BQ40Z50, BQ40Z50-R1, BQ40Z50-R2, … devices). 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 family of gauges 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.

Release Information

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:

  • Hardware: MKST-3P-ALT-EV2300
  • Supported operating systems: Windows (32 and 64 bits)
  • Software: Microsoft Visual Studio 2010 C++ Runtime redistributable

Features:

  • Collection of command line executables for Windows
  • Small executable size with few dependencies
  • Fast programming
  • Supports BQFS/DFFS and SREC file formats
  • Provides C API for custom code development
  • Callable from other programs for automation
  • Portable design simplifies deployment
  • Separately downloadable support software to enable legacy software like BQEVSW and ADVANCED-BQMTESTER to work with MKST-3P-ALT-EV2300

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.

What's new

  • Added support for BQ78350 and BQ34Z100
