BQ34Z100-G1推荐的chemical ID

Other Parts Discussed in Thread: BQ34Z100-G1, BQ27426

您好,我使用的电池是Sanyo NCR18650GA(3450mAh),通过BQ34Z100-G1采集的数据,使用GPC工具获得的chemical ID推荐如下,下面也有Sanyo NCR18650GA的chemical ID 1580,但推荐的最佳ID是2348,对于BQ34Z100-G1来说我应该怎么选择哪个chemical ID?下面的警告是什么意思,是否可以忽略?

Chemistry ID selection tool, rev=2.5

Configuration used in present fit:
ProcessingType = 2
NumCellSeries = 7
ElapsedTimeColumn = 0
VoltageColumn = 1
CurrentColumn = 2
TemperatureColumn = 3

Best chemical ID : 2348 Best chemical ID max. deviation, % : 1.87
