BQ34Z950: Error in Battery Capacity Calculation (Relative SoC and Absolute SoC)

Part Number: BQ34Z950
Other Parts Discussed in Thread: BQSTUDIO, BQ2050, EV2400

Dear All,

I am using BQ34z950 as a BMS for my battery pack. I have a battery pack of 16800mV 43200 mAh. Every time I read the Relative State of Charge(0x0D) register via SMBUS it shows 100, and Absolute state of charge(0x0E) shows 152. How to get correct values of these registers(since I think something is wrong). I write the Design Capacity(0x18) = 43200 mAh and design Voltage (0x19) = 16800 mV. 

Should I have to set the AtRate(0x04) with the value of current read from(0x0A)? Or I am leaving something behind?

Please help!!!!!!!

Regards,

Aman

  • Hi Aman,

    ASOC is remcap / design capacity. Please check the design capacity to ensure it is proper. If so, please check remcap and FCC to see if they're proper.

    Ensure that the device is using a learned pack.

    If issues persist, please describe the events leading up to a state of ASOC of 152. Please also describe the configuration steps that have been taken with the gauge and also provide a GG file.

    Sincerely,
    Bryan Kahler
  • Dear Bryan,

    Thanks for the reply. As per you asked I checked the remcap and FCC. Remaining capacity = 65335, FCC = 65335.

    I read all the configure register and values are as below.

    Regards,

    Aman.

  • Hi Aman,

    Thank you for including the settings of the device, however, some settings seem to be missing such as the RA tables and more. More information is needed.

    Please describe the events leading up to a state of ASOC of 152. A log file that captures the event in bqStudio would help along with your description.

    Sincerely,
    Bryan Kahler
  • Dear Bryan,

    Please tell me what exact register do you need or what setting I need to configure? Problem is I don't have EVM to read with bqStudio . I am configuring this via SMBus from uC. So I all I can do is read or write some registers and fill a sheet of it to show you.

    Today I send PFKey to Manufacturer Access of BQ and now the remcap is showing 0 and FCC = 7893.

  • Dear Bryan,

    Here is my values read from the BQ34z950. All RaTable and all. Sorry for being late.

    I don't know the float values are stored so I put the 4 bytes buffer of it as I readBq34z950 Settings Rtable.xlsx. If you can help to decode this that will also be very helpful.

    Regards,

    Aman.

  • In BQstudio there is not any BQ34z950 .bqz file. Please tell me how am I suppose to configure the bqstudio with EV2400 for BQ34z950. 

    Regards,

    Aman

  • Dear Bryan,

    Any Help!!!!!
  • I looked some previous threads regarding the BQ34z950 evaluation software. You guys ask for email to send. Please provide me on.
