Other Parts Discussed in Thread: BQSTUDIO
你好,我看网上GPC数据偏差都是1以下,我这边测试偏差2左右了,刚好达到3%的临界点。请问有什么经验可以提高精度吗?
1、官方推荐是5/30/50℃,我这边测试是用0/25/45℃,是否推荐的好点。
2、高倍率和低倍率电流分别多大最好,我用的是0.3C/0.7C
3、测试是单体测试还是成组测试好,我用的是成组测试,3S1P。
烦请TI的工程师们经验分享下,全部一个一个去验证太花时间了,感谢,

您好,Simple Guide to CEDV Data Collection for Gauging Parameter Calculator (GPC)文档中有介绍
低温典型值0°C or 5°C
常温典型值 25°C or 30°C
高温典型值 40°C or 50°C
