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
