Battery Voltage Recorder BVR22 is a handheld device intended for measuring string voltage, single cell voltage, inter-cell connection voltage, ambient / cell temperature. This device operates as an additional cell analysis tool during battery discharge testing with BLU series of devices. It also provides simultaneous battery current / voltage measurement in real time, for battery capacity determination during discharge testing with different battery load units on the market.
BVR22 can be used for measuring battery voltage while the battery is either connected or disconnected from the network, during battery’s periodic maintenance tests. BVR22 measures and records data in its internal memory, with an ability of storing measurements for up to 200 different strings. Measured parameters are displayed on the 2.8 inch color display.
Due to its ability to cover a wide voltage measurement range of up to 600 V DC, large battery banks as well as single batteries can be tested and supervised with this device. Download of collected data to an external computer is available via USB and Bluetooth communication. Detailed analysis and trending of battery banks and single batteries’ state of health is enabled by using DV-B Win software application set.
- Automatically measures, time-stamps, stores voltages in less than 1 second
- Simultaneous string (cell) voltage and DC current measurement, for use in the discharge test
- Voltage measurement range: ± 600 V DC
- Cell (electrolyte) temperature
- Ambient temperature
- RFID cell recognition
- Easy transfer of measured data to DV-B Win software
The software provides the possibility of setting additional parameters (cell voltage, string voltage, capacity and time) for alarming and ending the test. The setting of the profile modes is graphically displayed.
Using DV-B Win software all results saved in device’s internal memory can be downloaded and presented in several forms. The communication with PC can be established with USB cable or by using the optional Bluetooth module. Single-cell voltages can be shown in the table, histogram graph, as well as line view in order to present the behavior of all cell voltages during the discharge process. A test report of collected data can be generated and user-customized for comprehensive battery state-of-health assessment. Numerical and graphical results may be exported from DV-B Win in selectable formats such as Excel spreadsheet, PDF and Word.
