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 system of Battery voltage supervisor identifies a potential battery malfunction. That is done by monitoring the following cell parameters from an array of the cell voltage modules CVM:

• Cell voltage
• Intercell connection voltage
