关于BQ77PL900的vout输出电压,请教各位?



在手册上有这么一段话:

The total pack voltage can also be monitored. The PACK voltage output is enabled or disabled by
FUNCTION_CONTROL [PACK].
VOUT3 = (Total pack voltage) × 0.02 when PACK = 1
The total pack voltage can also be monitored. The BAT voltage output is enabled or disabled by
FUNCTION_CONTROL [BAT].
VOUT4 = (Total battery voltage) × 0.02 when BAT = 1

但是在测量的时候,误差总是很大不知道为什么,使用万用表直接测量这两个管脚时,上面的电压也比BAT+和pack+上的电压要低一些,不知道为什么,

希望能得到解答。

谢谢
