The 
BVS is an integrated system consisting of:
BVS Control Unit (BVS-CU)
Cell Voltage Modules (CVM)
String Voltage module (SVM) (optional)
String current module (SCM) (optional)
The BVS system identifies a potential battery malfunction by monitoring the following cell parameters from an array of the cell voltage modules CVM:
Cell voltage
Intercell connection voltage
