专家们好! 我们在使用BQ40Z80时遇到了与引用的帖子几乎相同的问题:
我们使用额定容量为9500mAh的电池,电量计经过校准,化学ID经过挑选(误差4.7%),虽然未经过完整GoldenLearing,但经过一定次数的放电循环,可以观察到FCC显示已经比较准确。
但容量显示上有点问题:当电池从0%开始充电时,FCC显示约7830mAh,RCC稳步增加。当电池从100%开始放电时,一旦电池电压低于CUV设定值,RCC突然从大约3800mAh跳到0,FCC从最初大约正确的7830mAh跳至4432mAh,放电FET自动关闭。这可能是什么原因?
Hello experts!
We encountered almost the same issue as the referenced post when using BQ40Z80: We use a battery with a rated capacity of 9500mAh, with a calibrated energy meter and selected chemical IDs (with an error of 4.7%). Although it has not undergone complete GoldenLearning, after a certain number of discharge cycles, it can be observed that the FCC display is already quite accurate.
But there is a problem with the capacity display: when the battery starts charging from 0%, the FCC displays about 7830mAh, and the RCC steadily increases. When the battery starts discharging from 100%, once the battery voltage drops below the CUV set value, the RCC suddenly jumps from approximately 3800mAh to 0, the FCC jumps from the initial correct 7830mAh to 4432mAh, and the discharge FET automatically shuts off. What could be the possible reason for this?
Thanks for your generous response!
