Other Parts Discussed in Thread: GPCRB
Hi sir,
A customer have inquiries on using BQ27542-G1.
could you please help me to clarify them?
When I using BQ27542-G1,
during the 0 degree charging process, the battery capacity is from 24% -- > 1% -- > 100%
So for this error, I learned about this file 'Golden GG Maker and Resistance Temperature Compensation Optimizer'.
GPCRB can be used for temperature compensation.
But I don't know how to implement it and how to provide correct information
------------------------------------------------------------------
Required Data
The GPC tool requires a single .zip file containing one configuration file, two data files at room and low
temperatures and one configuration parameters file (gg file) as input. The name of the .zip file is not
important. The .zip file should contain following files:
•config.txt
•roomtemp.csv
•lowtemp.csv
•gg.csv
--------------------------------------------------------------------
Q1.config.txt : what information should be included, how to make this file?
The configuration file is a text file named config.txt and is an ASCII text dictionary containing the following
information:
• ProcessingType = 4 <Determines the type of tool used. Value should be 4 for Resistance Temperature
Compensation Optimizer and Golden GG Maker tool>
• ChemID = <Chemical ID selected or released for your cell. Selection can be performed using GPC:
Chemical ID selection tool>
• NumCellSeries = <Number series cells for which voltage data in the log are reported. Note that if your
battery pack has 3 series cells, but your log file is for a single-cell voltage as is recommended, this
value should be 1>
• VoltageColumn = <Zero-based column number for the voltage data in your data logs>
• CurrentColumn = <Zero-based column number for the current data in your data logs>
• TemperatureColumn = <Zero-based column number for the temperature data in your data logs>
• ElapsedTimeColumn = <Zero-based column number for the elapsed time data in your data logs>
Typical settings are:
ProcessingType=4
ChemID=3514
NumCellSeries=1
ElapsedTimeColumn=0
VoltageColumn=6
CurrentColumn=4
TemperatureColumn=1
Q2. roomtemp.csv : room temperature charging (C / 20) -- > Room Temperature standing (2H) -- > Room temperature discharging (1c) - > Room Temperature standing (5H):
is the procedure correct, should Chem ID be included?
Q3.lowtemp.csv : low temperature charging (C / 20) -- > Room Temperature standing (2H) -- > low temperature discharge (1c) - > Room Temperature standing (5H):
is the procedure correct, should Chem ID be included?
Q4.gg.csv : (whether to include Chem ID)
Thank you for your response about the four questions.
Regards,
