Other Parts Discussed in Thread: BQ78350, BQSTUDIO
用bq76930+bq78350设计了一个电池管理电路，用来管理8节18650锂离子电池串联连接，原理图及电池连接示意图如BATBoard.pdf所示：
每节电池电压实际值为4150mV左右，但在bqStudio上显示的值却为4500mV左右，显示界面如下：
请问电池电压测量为什么不准确？为什么测量值比实际值偏高约300mV?电路设计是不是出了问题？谢谢！
您好，请参考下面建议
1- We noticed Schottky diodes are being used, which can cause error measurements. Can you change to conventional diodes and see if it fixes the issue? These should be conventional diodes. For more information reference to this E2E.
2- For a 8-series connection, we recommend to short VC9-VC8 and VC4-Vc3 cells
3- Filter components must be present at the supply pins. Please see attached video.
Note: Please ignore cell connections from VC10b and above as the BQ76930 only supports up to 10S.
