Battery voltage recorder BVR22 is designed to serve as a support tool for cell voltage measurement during battery capacity testing.
During capacity testing, cell voltage, temperature, inter-cell connection voltage, and specific gravity should be measured to determine failing cells in the string that should be replaced.
Furthermore, IEEE standards for stationary battery applications stipulate periodical measurement of overall string voltage, as well as cell voltage and temperature.
The BVR22 is the perfect tool for that purpose. All measurements are automatically saved in the device’s internal memory. Additionally, DV-B Win software helps the user to download all measured results. Furthermore, the user can create test reports and export them to various formats.
The BVR22 is a rechargeable handheld device intended for performing monthly battery inspections and support tools during capacity testing. The list of the applications of this instrument includes:
The BVR22 model provides Bluetooth communication with an external density meter, for transferring electrolyte-specific gravity and temperature readings.
The BVR Battery Voltage Recorder is designed for battery capacity testing, routine battery inspections, and detailed battery condition monitoring. It records cell voltage, string voltage, temperature, and other critical battery parameters to help identify weak or failing cells.
Cell voltage measurement helps identify underperforming or failing cells within a battery string. Early detection allows maintenance teams to replace defective cells before they affect overall battery performance and reliability.
The BVR22 can measure cell voltage, string voltage, DC current, cell temperature, electrolyte temperature, ambient temperature, and inter-cell connection voltage, providing a comprehensive assessment of battery health.
