ADVANCED-BQMTESTER: Works with THUMBUS2300

Part Number: ADVANCED-BQMTESTER
Other Parts Discussed in Thread: BQMTESTER, EV2400

Hi Guys,

Good day.

Our customer is looking for the EV2300 but it seems that this is no longer available. I found from the other posts that the THUMBUS2300 is the alternative.

I just like to confirm if the THUMBUS2300 works with the ADVANCED-BQMTESTER too?

Thanks to confirm!

Hello Art,

I believe the THUMBUS2300 should work as a replacement for the EV2300 according to the other E2E post: https://e2e.ti.com/support/power-management/f/196/p/385964/1365021#1365021?jktype=e2e

Let me double check if this is still the case.

Sincerely,

Wyatt Keller

Thank Wyatt for looking into this!

I read that THUMBUS2300 works for SMBus-based devices only?

How about the the other interface?

Hello Art,

This is the feedback I received:

Thumbus2300 may work for SMBus only. But TI has not tested it with any software. bqMTester requires the I2C port which is not available on Thumbus2300 so that combination is not expected to work.

It seems the thumbus2300 will not work with the bqmtester, I would recommend using the EV2400 to communicate with the bqmtester.

[EDIT] After talking with colleagues, the EV2400 does not support the BQMTESTER, you will need the EV2300 as stated in the BQMTESTER guide

Sincerely,

Wyatt Keller

So the Thumbus2300 won't work, the EV2400 won't work (although I saw a video that said that it SHOULD work...by Kevin?), the EV2300 is no longer available...so is the BQMTESTER actually useful for anything??

Hello Tim,

Let me check on this for you.

In the mean time, do you have an EV2300?

No, I have an EV2400, but the hardware is irrelevant. The real problem I am trying to solve is to find a way to automate device programming for a production environment, and I have to say that the complete lack of support for any quality production tools for these battery management chips is absolutely pathetic. And no, I am not going to sniff the bus and reverse engineer the protocol and write my own. TI has sooo much support for so many other great chips, but not these?? What a disgrace. Hopefully we will be using something else on the next rev.

Hello Tim,

I would recommend trying, looking through the forum it looks like others have had success with the EV2400, we will need to check internally if there is a mistake on the product page that needs to be updated.

We are working on adding more documentation for testing and running cycles on batteries.

Sincerely,
