Other Parts Discussed in Thread: EV2400, BQSTUDIO
Hi:
I am new user.I first want to get Chemistry ID by GPC tools.
I record data by bqstudio,HW:EV2400.
8662.config.txt
ProcessingType=2 NumCellSeries=1 ElapsedTimeColumn=0 VoltageColumn=1 TemperatureColumn=2 CurrentColumn=3
Why I record charge current appear -1~ -18 mA in the charge stage?
ElapsedTime,Voltage,Temperature,Current
9535,4170,32.0,3
9540,4170,31.9,-2
9545,4170,32.0,0
9550,4171,31.9,-7
9555,4170,32.0,6
9560,4169,31.9,11
9565,4170,31.9,2
9570,4170,31.9,2
9575,4170,31.9,0
9580,4169,32.1,-9
9585,4170,32.0,0
9590,4169,32.0,12
9595,4170,32.0,15

9620,4170,32.1,7
9625,4171,32.0,13
9630,4170,32.1,7
This condition is correct?
The GPC report give correct answer.

Warning: Last OCVpoint has non-zero current I= -0.09 Please make sure you have a 5 hr relaxation period after the end of discharge.
I worry problem in our Hardware device.
Please help me.
