Hi Team,
I want to ask a question about the setting of register 0x3B bit [15:14], bq24780S
These are bits to set battery depletion threshold to let IC exit LEARN mode and boost mode
Here is the things
For example, my battery pack’s cut off voltage is 12V, full-charged voltage 17.8V
So it’s a 3V to 4.45V cell basically
Base on datasheet’s instruction, 3V/4.45Vx100%=67.41%
I will set bits [15:14] to [1:1] to avoid my battery pack cut-off during boost mode
But however for LEARN mode
This threshold is too high so that the battery is not discharge completely for gauge learning
So how to trade off it?
Best regards,
Hardy
