Impedance Track is a trademark of Texas Instruments.
The bq20z80 SBS-compliant gas gauge IC, incorporating patented Impedance Track™ technology, is designed for battery-pack or in-system installation. The bq20z80 measures and maintains an accurate record of available charge in Li-ion or Li-polymer batteries using its integrated high-performance analog peripherals. The bq20z80 monitors capacity change, battery impedance, open-circuit voltage, and other critical parameters of the battery pack, and reports the information to the system host controller over a serial-communication bus. It is designed to work with the bq29312A analog front-end (AFE) protection IC to maximize functionality and safety, and minimize component count and cost in smart battery circuits.
The Impedance Track technology continuously analyzes the battery impedance, resulting in superior gas-gauging accuracy. This enables remaining capacity to be calculated with discharge rate, temperature, and cell aging all accounted for during each stage of every cycle.

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.

Description:
BQEVSW-MKST-UPDATE software is a software update for BQEVSW (bq Evaluation Software) and BQEASY (bq EV-Easy) to allow it to work with the MKST-3P-ALT-EV2300 MKS Technology alternative for EV2300 communications transceiver. This update installs a program that allows switching the USB transceiver target in software like BQEVSW and BQEASY from/to EV2300 to/from MKST-3P-ALT-EV2300.
The program requires administrator privileges.
Requirements:
Features:
Getting started:
1. Download the software
2. Run the installer and check the option to create shortcuts
3. Run the program using shortcut named BQEVSW-MKST-UPDATE from Start menu/Desktop
4. Allow administrator privilege when/if prompted
5. On the GUI window that opens, select the target transceiver to support and follow steps to switch
6. Connect matching transceiver and start BQEVSW, BQEASY or other similar software.
Note: BQMTESTER-MKST-UPDATE and BQEVSW-MKST-UPDATE both update the same software components. Switching the USB transceiver using any of these shortcuts will also switch it in the other.
| Important Note: The latest chemistry updater for bqStudio requires bqStudio 1.3.86 or higher. |
