使用BQ76940,级联方式,管理24节电池,在2A,5A,8A时候,出现异常的值,并且值都是多0x1000
目前使用75mv 100A分流器,麻烦帮忙看下可能是什么原因。

您好,请参考下面内容:
To confirm, the erroneous voltage only happens at 2A, 5A and 7A? If so it sound like it is a software issue. Have you looked into our example code?
Another possible scenario is that like mentioned in Question 6.3 Why does my voltage (or current) read erratically? of our bq76920, bq76930, bq76940 AFE FAQ document.
It could be the data is between one of these boundaries causing the error.
