BQ40Z50: bqProduction SBB

Part Number: BQ40Z50
Other Parts Discussed in Thread: BQPRODUCTION

Hi,

I used HPA495 and bqproduction software for bq40z50.

Currently, I used for 4S battery pack. It is good for 4S application.

But I wonder how to use for 2S battery pack?

I don't have manual and cable connection for 2S battery application in HPA495.

Please give me information for using 2S application.

Thanks,

Best regards,

HJ

    HI

        There is no much difference for 2s test, as bqproduction only calibrate cell1, BAT and Pack voltage, you only need to connect Cell 1-, Cell1+, Cell2+ and Pack+ to your target board. Please refer to below document for details

    Hi Steven.

    Thank you for your replying.

    But it is big different about pack+ voltage.

    4S pack+ voltage is 14.8V.

    2S pack+ voltage is 7.2V

    When connect 2S application, the pack+ is still 14.8V.

    My connection is below;

       [HPA495]             [2S board]

    1. CELL1- connect batt-

    2. CELL1+ connect 1st cell(3.6V)

    3. CELL2+ connect 2nd cell(7.2V)

    4. CELL3+ is not connected.

    5. CELL4+ is not connected.

    6. PACK+ connect 2nd cell(7.2V)

    7. PACK- connect pack-

    Is it right connection?

    Which number write in pack voltage 14.8V or 7.2V?
