Battery Voltage Supervisor – BVS

Overview


The Battery Voltage Supervisor (BVS) is a battery monitoring system for real-time data gathering and viewing. The BVS main role is monitoring battery voltage values during a battery discharge testing.

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

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 CVM 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 are available in the DV–B Win application software suite, providing a user data viewing, tracking and generation of comprehensive reports.


Main Features

  • Efficient analyzer for battery discharge testing
  • Automated string and cell voltage, and intercell connection voltage, string current and ambient temperature    measurements during capacity tests
