BQ78Z100: Lifetimes 更新

Part Number: BQ78Z100
Other Parts Discussed in Thread: BQSTUDIO

請教一下  生廠時燒入 校正後出貨至客戶端

客人充滿電後  發現

Lifetimes
Cell 1 Max Voltage , Cell 2 Max Voltage
Max Charge Current

都未更新 , 會是什情況造成

  • 您好,请参考TRM 12.2.18 AltManufacturerAccess() 0x0023 Lifetime Data Collection确认是否使能Lifetime Data collection

  • 確認是有開啟的   經驗證  我先完整放電  在充電就會更新了

    所以只有短暫充飽電是不會更新的 對吧

    另外請教一下 0x0071 0x0076  不知是對應讀取到哪個欄位

    客戶分位所設檢驗電池訊息如下

  • 您好,lifetime更新请参考下面的内容:

     Once the monitored value deviates out of original value more than specified value stored in dataflash, a timer is initiated with the value of LT Update Time, the most deviated value until the timer expires will be stored in dataflash. 

     0x0071 0x0076 请您在bqstudio的菜单栏点 Window/Preferences/All Global Settings 选择 Show Advanced Views. 这时参数的实际地址都会显示在data memory 中。
    如果您想把这份新的地址下载下来可以在Window/Preferences/Data Memory item选择Export All Columns. 您再导出gg文件的时候就能看见新的地址栏。
