Hi there,
My question is really easy,
What is the best algorithm, the "Impedance track" (IT) or "Compensated End-of-Discharge Voltage" (CEDV)?
I have read several pdf regarding this topic, at seems that the IT is better because take in account 2 key points more:
- Aging
- Self-discharging
I have to choose one of them. In my application the batteries achieves the requirements but on the limit. I mean that the nominal specs are enough; but I'm pretty sure that after some charge/discahrge cycles the batteries will lost some capacitive, and consequently won't accomplish the requirements.
Acording to TI pdf, seems that the IT algorothim is the better option because "meas" the impedance batery, which means that I can get all the capacity available in the batery. On the other hand the CEDV makes some "estimation" and consequently there are always some safe range wasted, I mean some remaining capacity on the battery which is not use.
What do you think? IT or CEDV?
Thanks a lot
