电池放电至3%的时候,插入充电器电量会跳到0再上升。这个会是什么原因引起的呀?

您好
Is this right after programing golden image on the device? If so, right after programming the golden image, did they send the reset command, and do a quick discharge for the gauge to adjust to the new battery?
I took a closer look at their files, and see the FD bit gets set when the jump happens. If I remember correctly, there is a bit which does not allow the SoC to jump to 0% unless the FC threshold is reached. They cound modifty those, but I don't have the .gg file to confirm what is their settings. Can you share it?
您好
我能看到设置项。我发现他们的设置是仅在电量剩余0%时才触发FD(功能禁用)。他们本可以切换到基于电压的设置,但除非刚连接充电器时存在噪声,否则我不明白为何会出现这种情况。如果存在电压振荡,那么很可能是仪表突然检测到极低电压,从而强制将电量显示为零。
如果他们在连接充电器前先松开电池,还能看到跳火吗?
