The best proven method for
determining whether a battery will perform is to test it under load
conditions. Proper load testing is the only way to determine where the
battery resides on its expected life curve. The Albér BCT-2000 capacity
test system will test any battery in service today.
Load testing is essential for any storage battery system that protects
equipment or a critical service. Because the battery is almost always the
least reliable component, load testing with the BCT-2000 should be done on
a regular basis to ensure reliability. The BCT performs battery load tests
using load banks or, in some cases, the actual system load.
Capacity
Test
The BCT-2000 performs a capacity test using a programmed, constant current
or constant power load. This test predicts reliability and remaining
battery life before replacement is necessary.
Integrity
Test
An integrity test, using a high current momentary load, lets you identify
weak cells and conduction paths.
Data
Acquisition Module and Data Logging Unit
The BCT is a combination load control and data logging system consisting of
a data acquisition module and a laptop computer data logging unit. The data
acquisition module acquires all cell voltage, overall string voltage, and
current readings and is available in 128 cell and 256 cell versions. The
computer data logging unit displays the programming parameters for the
test.
The BCT's proprietary
interface circuits and custom software control all standard Albér
continuous and momentary load units. The standard BCT-2000 can be
programmed to apply a constant current or constant power load on any
battery string up to 600VDC. During a load test, the system records overall
voltage, load current, and up to 256 cell voltages. Programmable alarm
levels warn of low voltages and can automatically pause testing before any
cell reaches reversal or an unsafe state.
