Hello Jonathan,

You can find these registers on the TRM found in the product website.

https://www.ti.com/lit/ug/sluubk0b/sluubk0b.pdf

1. The battery status register consists of flags related to the status of the battery including charge/discharge status, battery mode, gauge initialization among other flags.

2. This consists of flags such as charging voltage/current rate of change, high/low voltage regions etc.

3. This registers consists of flags for the gauging status, IT gauging, VOK etc.

4. See point 1.

5. Operation Status A and B registers consist of flags describing the current operating state of the gauge.

6. Manufacturing Status consist of flags indicating status of features of the gauge before manufacturing.

Regards,

Siddharth

Hi Siddharth,

For charging status what's the difference between :

FC?
TC?
VCT?

Which one of these flags is enabled when Pack reaches 100%

1. FC denotes Full Charge

2. TC is terminate charge

3. VCT is valid charge termination.

FC is enabled when the pack reaches 100%

Hello Jonathan,

Do you mean the current FW version of the gauge? You can find the FW version and build by clicking on the FW_VERSION/FW_BUILD command in the commands tab.

Siddharth

Hi Siddharth,

I've sent the commands as instructed and nothing showed the FW version of the gauge?,

is there a console or some sort of display that is meant to pop up?

See screenshot:

Hello Jonathan,

If you expand the results section, you might see 0x0211 (v2.11). This is the firmware version of the gauge. You can see this is consistent with the firmware version listed in the dashboard (4500_2_11).

Siddharth

Hi Siddharth,

thanks for those details

as for manufacturing access section

I believe there 's different manufacturing access for different functions such as PF,Fuses,FET control that we may use to troubleshoot, or test the device
