BQ34Z100EVM: Update Status卡在0x05迟迟不更新

Part Number: BQ34Z100EVM


根据官方文件 ,放电开始时VOK位会置1,但我实际加负载放电时,VOK没有跳变,仍然保持VOK=0。

等我放电完之后,静置五小时以上,upstate无法变为06。

之后我试着加了一下负载,此时VOK又跳变为1了。 技术手册上没有说明这是怎么回事。

  • 您好,数据手册介绍4. When discharging starts, ensure that the VOK bit is set. The gauge has the data flash parameter Dsg Threshold that determines the minimum current needed to enter the DISCHARGE state. If it discharges with less than this current, the VOK bit will not be set. The gauge will never go into the DISCHARGE state, and the Ra tables will never be updated. Update Status will be 05. Either decrease Dsg Threshold in the data flash, or increase the discharge rate.
