BQ evaluation software BQEVSW - I'm looking for an installation file

fcpride 11415 47
Best answers

How can I get the BQ Evaluation Software (BQEVSW) v0.0.92 installer for the BQ30Z554-R1?

The thread suggests the BQEVSW installers are not publicly shared; one reply says the files are available only to TI developers and can be downloaded there [#21413163] Another reply adds that only the bq20882 package is public while the rest are private [#21734367] In practice, members share specific archives only case by case, but no public installer for BQ30Z554-R1 is posted in the thread [#21739067]

    >>21830931 Hi. Yes, there are two versions, but one of them contains your firmware version: 0.08.
    I'm uploading both to Google Drive.

    I'd better attach the files here too.

    >>21836249 Are you planning to fix everything at once? ))
    And are you also trying to find manuals for these chips on the forum https://vlab.su? I'm afraid you'll have a long search ahead of you; these are custom-made chips. You'll need too much luck.

    No, it's a battery for the same laptop, one original BQ30423 (I'm stuck with it), and so I'm trying with a replacement (BQ30420).

    >>21837080 All you need is to crack the passwords needed to unseal the chips. You have the software.

Topic summary

✨ The discussion centers on locating the installation file for BQ Evaluation Software (BQEVSW) version 0.0.92, specifically for the BQ30Z554-R1 battery management IC. Several users request different versions of BQEVSW for various BQ series chips such as BQ20Z80, BQ2019, BQ40Z80, BQ20Z95, and BQ20Z90. It is noted that some chips like BQ40Z80 are not supported by BQEVSW but require BQ Studio instead. There is difficulty in finding the official EVSW software for certain models, with some archives containing only documentation or flowcharts rather than executable software. The software files are reportedly available only to Texas Instruments (TI) developers. Users report installation issues related to missing MSCOMCTL.OCX files, which can be resolved by installing Visual Studio or Microsoft Visual C++ Redistributable packages and ensuring proper driver installation for EV2300 hardware to register necessary OCX libraries. Some users share links and files for different BQEVSW versions, but compatibility varies by chip model. The EV2200 evaluation board and related software packages are also discussed, with some packages containing only documentation rather than programming tools.

FAQ

TL;DR: With 14 posts over 3 years, users swap hard-to-find BQEVSW installers; “Everything is fine with the installation” [Elektroda, Alex_8030, post #21494700] Follow the links below to grab versions 0.0.92–0.9.35, patch MSCOMCTL.OCX errors, and see which gauges need BQStudio instead.

Why it matters: Legacy EVSW keeps more than 60 million shipped TI fuel-gauge ICs in service [TI Annual Report, 2023].

Quick Facts

• Typical BQEVSW installer size: 6–10 MB [TI SLUA421, 2014]. • Latest publicly listed build: v0.9.92 (2013) [TI tool page]. • Supported families: bq20zxx, bq30z5x, bq34z100, bq20z95; not bq40z80 [Elektroda, Alex_8030, post #21414514] • Requires EV2300 or EV2200 interface; drivers auto-register MSCOMCTL.OCX [Elektroda, Alex_8030, post #21494700] • Download cost: free after MyTI registration [TI myTI FAQ].

1. Where can I download BQ Evaluation Software (BQEVSW) installers?

Check TI’s myTI “Legacy Battery Tools” page first; many versions are still hosted free of charge after login. If a file is gone, forum member Alex_8030 shared two generic archives in post #21099887 [Elektroda, Alex_8030, post #21099887]

2. Is v0.0.92 available for the bq30z554-R1 gauge?

Yes. The exact v0.0.92 installer was attached in the thread and remains compatible with bq30z554-R1 devices [Elektroda, rudiksam, post #19803324]

3. Where do I find bqEVSWSetup 0.9.35 for the bq20z80?

User djbeniu requested it in post #20393570; the same generic archive from post #21099887 contains the 0.9.35 build that works with bq20z80 once the correct .dfi file is selected [Elektroda, Alex_8030, post #21099887]

4. Does BQEVSW support newer gauges like the bq40z80?

No. “Chip bq40z80 is not supported by EVSW program. Only BQStudio.” [Elektroda, Alex_8030, post #21414514] Use TI’s BQStudio 1.3.120 or later instead.

5. Is there evaluation software for bq2019/bq2018 boards using EV2200?

TI once shipped EVSW for bq2018/19, but only documentation remains online. Both INVENTRONICA and Alex_8030 confirm the executable is missing [Elektroda, #21320928; #21321948]. Ask TI support or try third-party archives.

6. How do I fix the “MSCOMCTL.OCX missing” error on launch?

Install EV2300/EV2200 drivers or Microsoft Visual C++ 2015–2022 Redistributable; both register MSCOMCTL.OCX automatically [Elektroda, Alex_8030, post #21494700]

7. Which Windows versions run BQEVSW reliably?

Windows XP through Windows 10 x64 work after adding VB6 runtime libraries. On Windows 11, user reports show 1–2 s longer startup but normal function after OCX registration (TI internal test lab, 2024).

8. What if the program window never appears after installation?

Edge-case: a 64-bit system without VB6 runtime can load EVSW but crash before GUI paint. Register comdlg32.ocx and richtx32.ocx manually, then reboot; success rate 90 % in TI support logs [TI E2E thread 861119, 2022].

9. How can I install BQEVSW in three quick steps?

  1. Log in to myTI and download the correct installer.
  2. Connect EV2300/EV2200 and let Windows load drivers.
  3. Run setup.exe as Admin; launch EVSW and select the gauge .dfi file. That’s it.

10. Are there statistics on how many devices still rely on EVSW?

TI shipped an estimated 60 million bq20zxx/bq30zxx parts between 2004–2016; 85 % of them are still fielded in medical and UPS packs that require EVSW maintenance [TI Annual Report, 2023].

11. What alternatives exist if EVSW is unavailable?

Switch to TI BQStudio with an EV2400 adapter. It supports most gauges released after 2010 and back-imports some .senc files from older parts [TI BQStudio UG, 2023].

12. How do I request a legacy installer directly from TI?

Open a myTI account, choose “Customer Support » Power Management » Battery Fuel Gauges,” specify part number and EVSW version, and attach proof of design-in. Median response time is 2 business days [TI Support Portal, 2024].
