Testing
WARNING
See the chapter "2.2 Safety instructions"
on page 8. for safety precautions.
1]

9.2 BVM - Battery Voltage
Monitor
The BVM (Battery Voltage Monitor) is a battery volt-
age measurement device that is used for monitoring
of cell voltages and battery blocks in battery banks
commonly found in electrical power sub-stations, tel-
ecom facilities and computer data center UPS systems.
in conjunction the TORKEL unit, and test data man-
agement software, such as PowerDB or TORKEL Win,
the BVM enables a completely automated battery
bank capacity test to be performed.
BVM is available in three kits:
▪
BVM150 with 16 BVM units
▪
BVM300 with 31 BVM units
▪
BVM600 with 61 BVM units

The BVM is designed in modular form where one BVM
device is used for each battery or “jar” in the string
to be tested. it measures the voltage for each battery
cell and each unit can handle up to 20 V. The BVMs
connects to the batteries in a “daisy-chain” fashion,
thereby providing easy and economical expandability
to meet the testing requirements for small-to-large
battery bank systems. Up to 240 BVMs can be daisy-
chained in a single battery bank under test.
The included dolphin-style battery clamp can be easily
removed and exchanged with different styles of stand-
ard banana plug clamps and/or extension cables to
accommodate any battery connection requirement.
There is an Activity LED on the BVM that flashes when-
ever an individual BVM transmits data back to the data
acquisition host computer. This LED activity is useful for
indicating that the device is functioning properly.
