Problem：
中文：应用BQ76930作为前端来采集电芯电压，板上电芯连接如下：
VC0 - VC1----Cell1
VC1 - VC2----Cell2
VC2 - VC4----Cell3
VC4 - VC5----Cell4
VC5B - VC6----Cell5
VC6 - VC7----Cell6
VC7 - VC9----Cell7
VC9 - VC10----Cell8
发现一部分电池包存在上位机读取的电芯数值与实际用高精度万用表测量数值差异较大的情况，如图所示
从表中可以看出Cell1-Cell4万用表测量值和上位机读取值相近，但Cell5-Cell8两个种方式的测量值差异较大，超出了我们的规格，请问是什么原因导致这种差异？
English：Apply BQ76930 to collect the voltage of the battery cell, and connect the battery cells on the board as follows:
VC0 - VC1----Cell1
VC1 - VC2----Cell2
VC2 - VC4----Cell3
VC4 - VC5----Cell4
VC5B - VC6----Cell5
VC6 - VC7----Cell6
VC7 - VC9----Cell7
VC9 - VC10----Cell8
we found that some battery packs had significant differences between the cell values read by the upper computer and the values measured with a high-precision multimeter, as above in the figure.
From the figure, it can be seen that the measurement values of the Cell1-Cell4 multimeter are similar to those read by the upper computer, but the difference between the measurement values of the Cell5-Cell8 multimeter and those of the upper computer is significant, exceeding our specifications. What is the reason for this difference?
