Other Parts Discussed in Thread: BQ40Z50, BQSTUDIO
1)Hello experts, In the 4s application of the BQ40Z50, it was found that after over-discharge, after the discharge MOS was turned off, the charging could not be recovered.
Note 1: When the DC power supply is charged at a rate of 1v/ms, it is found that the flag bits ASCCL and ASCC turn red, and the charging rate can be recovered at a rate of 0.1v/ms.
Note 2: The test is a finished battery.
Note 3: After discharging the battery to over-discharge protection, use the DC power supply to charge it. The DC power supply model is Chroma 62006P-30-80.
2)ASCC setting parameters are as follows.
Question 1: Is ASCC protection related to the DC power output rate?
Question 2: Is there any other explanation for the above question?
