TI中文支持网Other Parts Discussed in Thread:BQ40Z50, BQ27426, BQSTUDIO
Dear:
下文是官网的回复，我用的是bq40z50的芯片，电池组是3p4s，单体电芯容量是2300mAh，
有两个问题：
1，对于“Best chemical ID : 1153 Best chemical ID max. deviation, % : 14.11” 的意思是，
（1） 有一个匹配的ID1153的电芯，是吗？ ——你能告诉这个电芯在哪里可以找到规格书。
（2）14 11 分别是指什么意思
请分别回复。

Star Xu：
您好
1，推荐的ID是1153，对应的规格书请根据Chemistry ID列表中对应的厂家型号在相关网站查找。
2，Chemical ID max. deviation14.11%，误差过大，一般推荐误差在3%左右。您使用3p4s学习还是用的单个cell学习。
如果是用4S3P学习的，建议用单个cell学习试一下。

您好，CHEM ID 误差偏大不建议使用。
