BQ4050: LEARN SOC推荐 5到12%,是否可以设置更高,比如19,如果接受附件的误差,超出范围会有其他什么影响?

Part Number: BQ4050

GPC CEDV tool, rev=60
Configuration used in present fit
NumCellSeries=4
CellTermV=2000
ChemType=6
ElapsedTimeColumn=0

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 2876
EDVC0 1101
EDVC1 0
EDVR1 127
EDVR0 3342
EDVT0 5296
EDVTC 11
VOC75 15464
VOC50 14653
VOC25 14217


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
