我想請問
若我放電過程會超過40度
是否會影響SOH的計算
Star Xu:
您好,不会影响SOH的计算。
SOH is calculated as QMax*IR@25C. You can see the gauge calcualation at [SOHFC@25C Q] register. In this equation I = DesignCapacity/SOH Load rate (default C/5). R is from the Ra table of the gauge. This value is then divided by Design capacity to report a %. The only thing that could really impact you would be 1) Writing Design Capacity wrong2) QMax update very small3) Ra update very large.

Wang Leo:
[SOHFC@25C Q]這個在哪裡可以看的到

Wang Leo:
另外在文件中有提到QMAX在超過40度會不更新,那這樣不會影響QMax*IR@25C這個公式嗎?

Star Xu:
您好,SOH是根据学习到的Qmax计算的,需要完全充放电,不完全充放电时,SOH可能无法计算和更新。
