BQ27510-G3: Calibrating wide temperature range batteries

Part Number: BQ27510-G3
Other Parts Discussed in Thread: GPCRB

Hi. I want to make the gauge learn from some wide temperature range batteries, and they are capable of charging/discharging within the temperature range of -10C~80C. I would like to run the learning cycle in 70C and 0C to see the performance of these batteries in extreme conditions. If I run the learning cycle in normal temperature conditions, it may generate incorrect results if the batteries will be used in extreme temperature conditions.

The gauge itself works within the temperature range of -40C~85C, which shouldn't be a problem. But the learning cycle has temperature requirements, which is 10C~40C, IIRC.

So the question is: Is there any way to lift the temperature requirements for a learning cycle?

    Hello Tian,

    You should not perform the learning cycle outside of the 10-40degC temperature range. You should use the GPCRB tool for temperature corrections if needed. I would recommend testing first with the learning cycle completed, if there are any issues then we can examine them.

    Sincerely,
