Hello,

1- Term Voltage is set incorrectly. This should be set to lowest discharge voltage. Right now the gauge understands that the lowest voltage is 32V. This is a 1S gauge, so the typical lowest voltage is between ~2.7 to 3V

Term Voltage

32767

2- Resistance update for the first grid point looks abnormal. This can cause FCC drop at end of charge. It looks like this cell has been cycled a couple of times. What was the initial Ra table? You might want to reset it to what it was after learning Ra table for first time. This might have been a symptom from setting lowest voltage incorrectly.

How is Ra0-14 and Rax0-14 distributed? Can you help introduce it.

I didn't understand that the first 9 grid points are spaced 11.1% DOD apart, and the last 6 grid points are spaced 3.3% DOD apart.

Ra anomaly; Can you help analyze which errors could cause abnormal updates here?

Hi Alex,
The gauge has 15 grid points. At these points the gauge run simulations and update Ra table. See this document to understand more about resistance update. https://www.ti.com/lit/an/slua450a/slua450a.pdf

To help you analyze the abnormal updates in Ra_0, I will need more info in the use case. It looks like the battery has been cycled. Have you been getting Qmax updates frequently? Can you attach the initial srec golden learning file?

Please attach the initial srec and the latest srec.

Hi Alex,

See the concerning changes between initial gg and 7 cycles later.

the IT Cfg class parameters should never be updated. These are fixed values. How did Term Voltage change from 2500mV to 32767mV? Please be careful when writing to DF. Normally in the field, the gauge should be SEALED to prevent DF writes.

It looks like the cell has only been cycled 7or 8 times. This is still a fresh pack. I suggest to re-program the initial golden image (srec). Then Seal the device and run a few cycles. See if the R_a 0 value changes abnormally again. If it does, please reach out again with this manner.
Looks like every other grid point updated ok.

HI Jose

I reprogrammed the initial golden image (SREC), but I found that the voltage was around 3V when the SOC was 0%. I set Term Voltage to 2500mV.

The attachment is log.

Also, I would like to inquire about the Ra0 (0) update exception. Was it caused by the last DOD0 collection exception after it was fully charged?Or
Is there any other possibility?

Is there such a correspondence between DOD and Ra table(red font)

Hi Alex,

You are testing constant current, please change Load Mode to constant current. If this does not work, you can potentially decrease term voltage to 2300mV and increase remaining capacity to report 0% right at 2.5V. See section 3 in this App Note. https://www.ti.com/lit/an/slua948/slua948.pdf

Gas Gauging

IT Cfg

Load Mode

In regards to Ra_0:
If DOD0 is different from DODatEOC (DOD when Valid Charge Termination occurs), then there’s a problem with either DOD0 or DODatEOC. Looking at your log file, it looks like you charge up to ~3596mV. But, the highest voltage on your ChemID is 3375mV. This can create discrepancies in DOD0. To compensate the gauge will increase the Ra_0 to increase the IR drop at end of charge so that DOD0 matches DOD_at_EoC.

Question:
Did you match a ChemID? or did you send your cells for ChemID creation?

The GPCRA0 tool will output the right value you need for Ra_0.

Hi Jose

1、After changing the load mode, I will continue testing;

2、“the highest voltage on your ChemID is 3375mV”，How was this calculated? Can you introduce it. Thank you very much.

3、chemID is sent to TI for testing;

The test results are as follows:

ChemID #4162 is complete!

Hi Alex,
Good to know the ChemID was created.

It looks like this is an LFP chemistry. This will explain why the DOD0 does not correspond to the first OCV voltage. For this we have LFP_RELAX bit. Which looks like you already have it set.

What must be done is use GPCRA0 too to obtain the right Ra_0 value.
