BQ40Z50-R2: Golden Learning failed, Updata Status is always 0X04

Part Number: BQ40Z50-R2
Other Parts Discussed in Thread: GPCCHEM

HI,TI engineers

I do not know why I failed to study Golden Learning. In the S2 phase, the FC is set, and after 2 hours of inactivity, it is found that REST = 1, VOK = 0, but the Updata Status is always 0X04 and does not change. Did not continue to learn. (SLUA903: 3.2.1 An alternative method.I used the method of GAUGE_EN = 0 to disable in the S0 phase, and let it stand for 5 hours, then turn on GAUGE_EN = 1, and start charging in the S2 phase)

Repeating the S0-S2 stage several times is the result. Searching gg.csv, I found that the EoC has been updated. 

Battery pack configuration 4S3P,When choosing chemistry ID:5267, I used the following options,Found that the battery model is inside。

The gg file is as follows:

  • Hello Li,

    Please share the log file as well as the .gg from before and after the test. This is the best way for us to help.

    One of the most common reasons is the wrong chem ID is uploaded (please check by using the GPCCHEM tool, not only by matching the name) or you don't get the 90% DOD change required on the first cycle.

    Sincerely,

    Wyatt Keller
