Other Parts Discussed in Thread: GPCCEDV
我已经通过www.ti.com.cn/.../GPCCEDV三个步骤得到GPC报告,下一步该怎样做?判断报告是否符合,然后将log数据的那组电池的固件导出来作为量产文件烧录到其他电池?

您好,请参考下面的报告例子
GPC CEDV tool, rev=46
Configuration used in present fit
NumCellSeries=5
CellTermV=3000
ChemType=1
VoltageColumn=1
CurrentColumn=2
TemperatureColumn=3
ElapsedTimeColumn=0
FitMaxSOC%=12
FitMinSOC%=6
LearnSOC%=7
CEDV parameters resulting from the fit. If EDVV bit is set to 1, EMF and EDVR0 have to be multiplied by the number of serial cells when written to data flash
EMF 3399
EDVC0 119
EDVC1 0
EDVR1 6693
EDVR0 95
EDVT0 2799
EDVTC 9
VOC75 19725
VOC50 19065
VOC25 18770
Recommended SOC deviation tolerance at EDV2 point is < 5% for low temperature and <3% for room and high temperature
Deviations for this set of parameters are given below for each file
file SOC error, % pass
roomtemp_lowrate.csv 1.64633293725334 1
roomtemp_highrate.csv 0.210781856331618 1
hightemp_lowrate.csv 1.84509116228294 1
hightemp_highrate.csv 0.722007649606207 1
lowtemp_lowrate.csv 1.05855412810899 1
lowtemp_highrate.csv -0.316459549357137 1
Deviations are within recomended range. CEDV parameters are suitable for programming the gauge
上面的CEDV的参数就可以用。
您好,报告中给出的这部分参数

VOC50 19065
VOC25 18770
将参数修改以后还需要做完成的学习才能生成量产文件。
之前做了6个状态的循环是为了得到CEDV的相关参数。
