BMS63EN connection problem

BMS63EN connection problem

I connected AEK-COM-ISOSPI1 and BMS63EN through PinMap provided by SPC5.
However, I found two problems.
1. When the input voltage is 56V, when I measured the voltage of Cell0, the voltage was measured as 10V~12V, and the voltage of other cells was measured as 2V. I confirmed that the voltage of the cells was gradually decreasing.

2. When I disconnected the ISOfrequency connection to AEK-COM-ISOSPI1, I confirmed that the voltage of Cell0 was measured as 4.2V, and the voltage of the remaining cells was 3.7V.
(However, communication did not work.)

There is also a problem in case 2. (When AEK-COM-ISOSPI1 and BMS63EN are separated, each cell voltage is measured as 4V.)

How can I solve the problem?

Hey,

 

Could you let me know if you were able to figure out the issue? I am also facing a similar problem where I have connected the slave BMS69EN with the cells and voltage is not being read correctly. 

 

Any help would be appreciated. Thanks!
