BQSTUDIO: Battery Characterization

Part Number: BQSTUDIO

Hi, 

I have a Lithium Ion battery and I am planning to use BqStudio to find out the ChemID in order to either pick a ROM type gauge (if the deviation is less than 3%) or go with a Flash type. I have read the technical documents and the forum but I still have the following questions:

- It looks like the process would take around 20 hours to generate the data because of the timing requirements. I was wondering if we need to exactly follow the required time for relaxation? Can it be more than 2 hours (SLVA725A - step 3.1.3) and/or more than 5 (SLVA725A - step 3.1.5). The company is not normally open 24 hours...

- I saw in the forum that it can be possible to find the CHEMID for a battery without actually performing the testing. Do you have a database where I can check if this battery is there? 

Thanks.

  • Hi Leinho
    When you install bqstudio, go to the chemistry tab and search through by nomenclature to see if you will find your cell with an exact match. Alternatively, there is a chemdat.txt file in the bqstudio location as shown below on your computer. it will contain the list of all the chem ids. You need to make sure the id matches.
    C:\ti\BatteryManagementStudio\chemistry


    you can also automate the chem id identification process so you don't have to be there when it is running. We have a hardware tool you can use to do this. It is GDK

    thanks
