Description
The Battery Voltage Supervisor is a battery monitoring system for real-time data gathering and viewing.
This system’s main role is monitoring battery voltage values during a battery discharge testing in order to meet IEC, IEEE and NERC requirements.
The Battery Voltage Supervisor is an integrated system consisting of:
– Control Unit for BVS or BVS-4 (BVS-CU)
– Cell Voltage Modules (CVM or CVM-4)
– String voltage module (SVM) (optional)
– String current module (SCM) (optional)
The BVS-CU performs monitoring and measurements data acquisition from the Cell Voltage Modules and transfers this data to a PC. In addition, the BVS-CU provides power supply to all connected modules. Cell Voltage modules are used to measure cell parameters.
Depending on the type of cell voltage modules used, DV Power provides two models of Battery Voltage Supervisors:
- – BVS – One cell voltage module (CVM) measures one cell
– BVS-4 – One cell voltage module (CVM-4) is connected to 4 cells and measures the voltage of each cell
BVS and BVS-4 systems act as an add-on to the Battery Load Unit (BLU) series of devices while performing a battery discharge test, providing detailed analysis of an individual cell’s condition. The system identifies a potential battery malfunction by monitoring the cell voltage parameters from an array of the cell voltage module.
In addition, the BVS-CU provides ambient temperature measurements on multiple locations (4 temperature channels). Overall string voltage and string current measurements can be achieved by using optional string voltage module (SVM) and string current module (SCM).
The Cell Voltage Modules detect cells that fail a discharge test based on measured voltage values, so these cells can be safely removed from the battery string.
Data acquisition and extensive analysis capabilities of data collected from the modules is available in the DV–B Win application software suite, providing a user data viewing, tracking and generation of comprehensive reports.
