Release Information

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

Overview

bqProduction Hi-cell software offers a full suite of robust tools to assist with the process of configuring, calibrating, manufacturing and tracking printed circuit boards utilizing TI Battery management products. This includes features that allow writing a golden image followed by different types of calibration to provide desired levels of accuracy, writing date of manufacture, writing unique serial numbers, and finally validating limits for calibration parameters to spike out any inconsistencies in material. bqProduction Hi-cell software 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. bqProduction Hi-cell software supports a single station from a single computer and has inbuilt capability to maintain log files for the processed printed circuit boards.

Requires

MKST-3P-ALT-EV2300

Mode of operation dependent: Requires 1mV, 1mA accurate external power supplies able to supply current required for calibration.

Features

  • Support for MKST-3P-ALT-EV2300
  • Uses industry standard Motorola SREC format golden image programmer
  • Calibration and test automation
  • Unique serial number assignment/programming
  • Supports bq34z100-G1, bq34110, bq78350

MKST-3P-ALT-EV2300 is used as a substitute for EV2300. Separate installers may be provided for each family of products and build numbers may vary by device family.

Limitations: Recommended display resolution is 1920x1080 with maximum 125% scaling. The GUI may not show password fields and/or buttons may be moved out of the visible area when using other display settings.

 

What's new

  • Uses MKST-3P-ALT-EV2300 instead of EV2300
  • Adds support for bq78350 family of gauges
  • Separate installers for each family of products

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.

Release Information

Important Note: The latest chemistry updater for bqStudio requires bqStudio 1.3.86 or higher.

 

Instructions for bqStudio Chemistry database update:

  • 1. Download the "bqStudio Chemistry Update zip" file and save with extension *.zip
  • 2. Connect an impedance track(IT) enabled gauge to the PC and open Battery Management Studio(bqStudio). bqStudio must autodetect the gauge. Alternatively select impedance track enabled gauge from selection list.
  • 3. From bqStudio "Help" menu select "Update Chemistry". When prompted point bqStudio to the downloaded zip file. Upon successful update, a confirmation message will be shown.
  • 4. For chemistry updaters later than 1090, you must use bqStudio version 1.3.125 Build 10 or later. 

Instructions for bqEVSW Chemistry database update:

  • Run the installer to update the chemistry database used by bq Evaluation / bqEasy software
