BQ27Z561-R2: 松下 NCR18650BD 做出来的ChemID 是 2052 但是在TI的Chemistry中对应的是2072 这是什么原因?

Part Number: BQ27Z561-R2


你好:

我的问题是:

我用松下 NCR18650BD 做出来的ChemID 是 2052  但是在TI 的 Chemistry中对应的是2072 这是什么原因? 是哪里有问题?

我用的是充电测试设备采集的数据,按照0.5C CC-CV  4.2V  截止电流小于1/100C  搁置2小时 然后用0.1C放电 放到2.5V  搁置5小时。  得到的数据 上报到TI 得到的报告就显示是2052 这个CHEMID

Best generic ID 3142		
Warning: Deviation for best generic ID is above recommended level for this device / family. Consider using another device, flash based gauge or RAM programming of custom ID.		
		
		
Device / Family #2		
Generic Chem ID	Device/ Voltage/ Chemistry	max DOD error, %
354	bq27621:  (ALT_CHEM2) 4.35V LiCoO2	18.48
1202	bq27621: (default) 4.2V LiCoO2	20.85
1210	bq27621:  (ALT_CHEM1) 4.3V LiCoO2	22.91
Best generic ID 354		
Warning: Generic ID Deviation is so high that it is most likely due to anomaly in the data. Please check that data files have recomended format, units and test schedule
