BQ20Z40: automation tool for mass production

Oscar C
Prodigy 20 points
Part Number: BQ20Z40
Other Parts Discussed in Thread: MKST-3P-ALT-EV2300, BQ-BATTERY-PROGRAMMER-SW

Tool/software:

Hello,


there is a pcba with the bq20z655 gas gauge which needs to be tested for mass production
The current test procudure specifies the use of the bq evaluation software and the EV2300 module
however, it is a manual process. Is there any tool (Command Line Interface) to automate the process for mass production?

Some of the test item includes:

1. programming senc file
2. pack voltage calibration
3. CC offset calibration
4. Calibrate voltage
5. Cell overvoltage
6. Temperature calibration
7. Current calibration

Best,

    Hello Alan,

    Thansk for the reply! Becasue this is my first post, I'm not sure how exactly it can take. Is there any contact to reach out by email? It would be great to follow up the discussion by that means. If additional equipment/hardware/software will be required for the testing, it is suitable to get quoation/estimation by email

    Thanks,

    Oscar

    Hello,

    The BQ-BATTERY-PROGRAMMER-SW SDK is the most suitable command-line tool for automating the mass production testing of bq20z655 gas gauge PCBAs. It supports all your test requirements (programming .senc files, voltage/current/temperature calibration, CC offset calibration, and overvoltage testing) and can be integrated into an automated test setup.

    Hello Jose,

    Great! I will take a look.

    Thank you guys

    Hello,

    Is there any document where this SDK is used and implemented using Python? Can you guy share it?

    It would be useful to take a look in the calibration process (voltage/current/temp) using this software and the MKST-3P-ALT-EV2300 board

    Thank you in advance,

    Oscar

    Hello,

    While the BQ-BATTERY-PROGRAMMER-SW SDK includes Python examples for custom development, specific documentation for the bq20z655 and MKST-3P-ALT-EV2300 calibration process is not available. The SDK’s Python examples, found in the install directory, provide a starting point for automating voltage, current, and temperature calibration. Use the outlined calibration process, referencing the bq20z655 TRM and SDK Readme.txt for command details.
