Other Parts Discussed in Thread: BQ25792, GPCRB
Hello,
We use it on the battery protection board and during testing, it was found that when the temperature drops to a certain value (such as -20 ° C),
the battery capacity read through I2C is 0 (the actual capacity should not be 0, it should be close to 70%),
and we also read it as 0 through the Battery Management Studio tool (as shown in the figure below).
At this time, we restore the temperature to room temperature, and the battery capacity reading value remains unchanged, always 0.
What is the problem? Is there a solution?
best regards!
