Battery Voltage Recorder BVR11 is a handheld device intended specifically for measuring string voltage, single battery voltage and ambient temperature.

BVR11 can be used for measuring voltage and temperature parameters while battery is either connected or disconnected from the network. BVR11 measures and records voltage and temperature data in its internal memory, with an ability of storing up to 1000 measurements. Measured data is displayed in the form of histograms on the 2.8 color display.

Due to its ability to cover a wide voltage measurement range of up to 500 V, large battery banks as well as single batteries can both 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.

DV-B Win

DV-B Win software provides a full range of parameters for detailed battery testing and analysis. Setting battery parameters (cell voltage, string voltage, capacity and test time duration) for alarming and acknowledging failing cells is enabled. Setting of profile modes during battery discharge testing is an additional option, and graphically displayed. Using DV-B Win during discharge process, current, voltage and capacity values as well as the waveforms can be observed. All measured data from BVR series of devices is graphically displayed in histograms and table views as well.
