Hi,

i evaluate right now the bq27530evm board and i was wondering how to write the chemistry information of my battery pack in the chip.

With the bq27510 i'm was using bqeasy. Exist something similar for the bq27530?

Regards,

Alex

The tool to use for chem ID programming is bqConfig:

This tool can also guide you through setting up some of the other parameters as well. It is similar to bqEasy, but it is standalone rather than a plugin.

Hi,

thank you for the reply.

I've installed the tool but as you can see an error occur on scanning although some informations from the bq27530 are displayed in the status line (see attached file).

So no further action can be taken. Did you have any idea what is the reason?

If you send me your SENC file in a private message I can update the chem ID for you.

Which are the steps for creating the SENC file?

I'm able only to export the data flash contents as a .gg file.

Were you able to get bqEVSW to work? If so, you read out the SENC file using the I2C Pro Screen. Write 000f to address 00. This will put the gauge in ROM mode. Then at the bottom you can read out the SENC file.

Reading the SENC file issues an error. See the attached picture.

At the moment i have no idea why I'm not been able either to use bqconfig or to read SENC file using bqevsw.

I will try on another computer.

The installation on another pc was helpful. Now I'm able to use bqconfig. Now I will try to update the chemistry in the bq27530. If any problems occur i will post it.
Many thanks for your help and recommandations.

I have a additional question.
My chemical ID 2012 is not available in bqconfig. The chemistry updater software found on ti web can only update the bqEVSW. Exist a way to do this also for bqconfig?

Regards,
Alex

Just to make everyone aware - bqConfig is an older, outdated tool which has been obsoleted. However, note that the bq27530-G1 is now supported by the latest release of bqStudio.

Thanks,

Terry
