Dear, All
"3. GPC - Optimize room and low temperature performance. Includes (2)."
Log data was uploaded to the above system.
As a result, due to problems, I have two questions about the bq 27421-G1 Technical Reference.
The first question is about Qmax Cell 0 formula.
"6.4.2.3.1 Qmax Cell 0"
The following equation is described.
Qmax (mAh) = Qmax Cell 0 × Design Capacity / 2^14
If Qmax Cell 0 is Default value, does this mean the same value as Design Capacity?
In this case, in GPC_report
Qmax, mAh: 233195
And it was output.
This value does not match.
What should I consider?
The second is the setting value of Ra.
The following values were specified as NewRa.
DOD Ra, mOhm
0 2
0.111 2
0.222 2
0.333 5
0.444 3
0.556 3
0.667 4
0.778 5
0.81 6
0.841 5
0.873 5
0.905 6
0.937 10
0.968 26
1 32
An expression to convert it to a value for setting R_a RAM from this value was not found.
Please tell me this equation.
Thanks, Masami M.
