Overview

The bq40z80 EVM includes one bq40z80, two bq771807 secondary protectors, and a link to Microsoft Windows based PC software, which can be used to monitor and predict capacity, perform cell balancing, monitor critical parameters, protect the cells from overcharge, over-discharge, short circuit, and overcurrent in 2-, 3-, 4-, 5-, 6-, or 7-series cell Li-ion or Li-polymer battery packs. The circuit includes an on-board EV2400 interface to USB so the software can read bqz40z80 data registers, program the chipset for different pack configurations, log cycling data for further evaluation, and evaluate the overall functionality of the solution under different charge and discharge conditions.

Features
  • 2s-7s battery gauging with protection
  • Supports internal and external cell balancing
  • Multiple GPIOs and LED support
  • Protection features include:
    • Over and under voltage
    • Short circuit in charge and discharge

Release Infomation

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
TI's Standard Terms and Conditions for Evaluation Items apply.
