Other Parts Discussed in Thread: GPCRB
Gentlemen:
I am encountering a situation with a design for which I could use your assistance.
I have created several packs for a customer who has some extreme low-temperature requirements. When the pack is discharged at low temperatures (around -20°C), he reports that the capacity reading remains at 100% for approximately 10 minutes after the pack begins charging, and still reports approximately 25% SoC at the pack voltage cutoff. He has not mentioned having the same problem at room temperature or at elevated temperature.
Does the bq40z50-R1 take cell temperature into account when calculating remaining capacity? I am aware that the capacity of LiFePO4 cells is temporarily reduced when operating at low temperature. How can I compensate for this when operating the pack at low temperature?
