Battery voltage recorders from BVR series are designed to serve as a support tool for cell voltage measurement during battery capacity testing. \n \n
During capacity testing, cell voltage, temperature, inter-cell connection voltage, and specific gravity should be measured in order to determine failling cells in the string that should be replaced.
Furthermore, IEEE standards for stationary batteries applications stipulate periodical measurement of overall string voltage, as well as cell voltage and temperature.
The BVR Series is the perfect tool for that purpose. All measurements are automatically saved in 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.
BVR series includes two models: BVR11 and BVR22. These are rechargeable handheld devices intended for performing monthly battery inspections and support tools during capacity testing. The list of the applications of these instruments includes:
Efficient supplement to BLU series of battery load units during battery discharge testing
Monthly inspections of large battery banks
Ambient temperature measurement
Current measurement using current clamps
USB and Bluetooth communication with PC
Simultaneous string voltage and current measurement to analyze a discharge test process
The BVR22 model provides Bluetooth communication with an external density meter, for transferring electrolyte specific gravity and temperature readings.
The Battery Load Unit – BLU340A is a stand-alone or a PC-controlled battery capacity test set, based on the state-of-the-art technology, using the\n most advanced power electronics solutions with coolers and fans integrated into device itself.\n The BLU340A device is a lightweight solution (20,6 kg / 45.4 lb.), developed to meet a customer’s wide ranging test procedure requirements (standardized\n as well as customized).

BXL is an extra load unit designed to be used with DV Power’s BLU series battery testers. However, this unit is a universal add-on device. Because of that, it is compatible, as an additional load, with any other discharge/capacity tester in the market.\n
\n
In case when discharge current exceeds the capacity of a single BLU device, BXL can increase the discharge capacity. There are no limitations on the\n number of extra load units that can be connected in parallel to the main battery tester.
\n
A system of BLU and BXL instruments enables performing the capacity test in an accurate, user-friendly way. Also, all instruments are in accordance\n with battery testing standards: IEEE 450-2010, IEEE 1188-2005, IEEE 1106-2015, IEC 60896-11/22, and other relevant standards.
\n
These units can be used on any type of battery string, such as lead-acid, Li-Ion, Ni-Cd, etc. They test battery strings with voltages in the range\n of 5,25 – 500 V DC. On the other hand, current up to 250 A can be discharged through the BXL internal structure.
\n
The instrument simulates a constant resistance load during the discharge test. Several resistances can be set for different battery nominal voltage\n levels. This makes BXL extremely flexible in selecting its load capabilities.
DV Power battery voltage supervisor – BVS, is an accurate battery voltage monitoring system which determines the state of health of battery systems. It monitors important battery parameters such as battery voltage\n , inter-cell connection voltage, and ambient temperature. Because of that, it can be a support tool for capacity testing.
\n
The BVS voltage supervisor is an integrated system consisting of:
\n
\n
BVS Control Unit (BVS-CU)
\n
Cell Voltage Modules (CVM)
\n
String Voltage Module (SVM) (optional)
\n
String Current Module (SCM) (optional)
\n
\n
It is an ideal testing tool for maintenance, troubleshooting and performance tests on individual stationary batteries and battery packs in critical\n backup energy solutions.
\n
BVS-CU provides ambient temperature measurements on multiple locations (4 temperature channels). Overall string voltage and string current monitoring\n can be achieved by using an optional string voltage module (SVM) and string current module (SCM).
\n
CVM modules detect cells that fail a discharge test based on monitored voltage values. As a result of that, these cells can be safely removed from\n the battery string.
\n
Data acquisition and analysis of data collected from the modules are available in the \n DV-B Win application software suite. They provide data viewing, tracking, and generation of comprehensive reports.
