BQ76940+BQ78350电池电压校准错误

Other Parts Discussed in Thread: BQ76940, BQ78350

使用BQ78350+BQ76940做BMS,采用15节LI-PO电池,目前使用EV2300通过SMB总线可以和BQ78350通信。

问题1:进入Calibrationbq78350页面,做所有的校准,均报错,

下面的状态栏显示:Raw calibration block size returned after command 0xF081 or 0xF082 is an incorrect length.

这是什么原因?

问题2:读取电池状态的时候,15节电池的电压可以正常读取,TS1,TS2和TS3的温度也正常,但是,Cell Temperature不正常,这是啥问题呢?
