BQ40Z50-R3-DEVICE-FW: Resetting Pack to Appear New for Golden SREC

Part Number: BQ40Z50-R3-DEVICE-FW

Hello,

After I get my cell chemistry, learning cycle, and configuration in place, I'd like to save aside a "golden SREC" to use to flash additional parts. 

Before I do that, is there any mechanism to reset much of the info that the BQ tracks that is specific to a given part? (fault counts, cycle count, max charge/discharge current values, etc.) Or, do I have to manually go through and reset everything? 

Thanks!

    Hello,

    You can reset, but make sure to dump out a gg.csv file if you want to preserve any information prior to the reset.

    Are you referring to these commands:

    15.1.24 ManufacturerAccess() 0x0028 Lifetime Data Reset
    Sending this command resets Lifetime Data in data flash to help streamline production testing.

    15.1.25 ManufacturerAccess() 0x0029 Permanent Fail Data Reset
    Sending this command resets PF data in data flash to help streamline production testing.

    15.1.26 ManufacturerAccess() 0x002A Black Box Recorder Reset
    Sending this command resets the Black Box Recorder data in data flash to help streamline production testing.

    If I understand these correctly, I could issue them as necessary before saving aside my "golden SREC", so this seems like what I want. Thanks!
