Operating Manual
NOTE: 100% discharge is never 0 volts for any battery type. There is an industry standard for each chemistry:
Lead-Acid is 1.775 volts per cell
Nickel is 0.9 volts per cell
Lithium is 2.8 volts per cell.
The 100% discharge voltages may vary slightly between different manufacturers and may be dependent on
temperature. It is recommended to verify this voltage from the battery manufacturer’s specification.
Hardware
In the orange area select the CBA unit that is going to be used. If the CBA units are connected in parallel to
increase the current, then enter mulitiple units. When using an amplifier for even more current, select that here
as well.
Test Type
Mission
Profile
This is a simplified discharge test. There is an option to run
a test until it meets the requirements of the application (Pass)
or run until the battery is depleted before the minimum time is
reached, the test fails.
Discharge
Using a constant current discharge, the battery voltage lowers
until the cut-off voltage is reached and the test stops.
Charge
Monitor
Using this test, the CBA will strictly be used to monitor the
voltage; the CBA will not draw any load from the battery.
Time
Discharge
This test will discharge the battery until the user specified
duration has expired, and then stop the test. This differs from
the normal Discharge Test, which would discharge a battery
until cut-off voltage has been used.
Power
Profile
The test continuously increases the load by the Current
Increment while the voltage is graphed versus current or
versus power. Using a voltage versus power graph, the peak
power output of a battery or power supply can be accurately
measured.
Duty Cycle
The CBA draws a load for a set duration, then stops drawing a
load for set duration, and then repeats until the cut-off voltage
is reached. The load can be configured to be constant
current, constant power or constant resistance.
