Hello
I need to have a certain amount of reserved capacity, not negligible (say 1000mAh, around 10%) and started to make some testing.
I noted that:
- The DF:FCC is the correct chemical capacity (9900mAh)
- The SMBus reported FCC 0x10 is the usable capacity and is equal to DF:FCC-ReservedCapacity (8900mAh)
- SOH unfortunately is affected by the Reserved Capacity because it returns (DF:FCC – Reserved Capacity)/ DesignCapacity, showing 89% (8900mAh / 9900mAh)
So I thought to cheat the design capacity setting it = Cells Design capacity - Reserved Capacity (8900mAh)
SOH is now coherent and does not alert the user misleading the idea of an inefficient battery: 100% (8900 mAh / 8900mAh).
At this point what happens if in my configuration if I also have FCC_LIMIT=1 in CEDV configuration ?
At the next learning cycle, if suppose the gauge will learn a real 9700mAh, will the DF:FCC be capped to Design capacity (8900mAh) causing the SMbus 0x10 to report 7900mAh ?
Or the DF:FCC will be capped considering th Reserved Capacity, in a way so that SMbus 0x10 will report 8700mAh ?
Thanks in advance
Pietro
