Multiple
CBA tests the battery or supply given user defined
programming profile. Each step of the profile can
be configured for load amount and duration, and the
load amount can be confgured as constant current or
constant power. The profile can also be imported from
other analysis tools.
Constant
Power
The CBA draws constant power from the supply or
battery under test. As the battery voltage decreases
during discharge, the load resistance is decreased, thus
increasing the load current to maintain constant power
per Ohm’s law: P=V*I
Constant
The CBA acts as a constant resistance to draw a
load from the supply or battery under test. As the
battery voltage decreases during discharge and the
load resistance is held constant the load current will
decrease per Ohm’s law: R=V/I
C h a r g e /
The CBA discharges the battery, and the CBA Charge
Controller activates a charger to recharge the battery. The
software can repeat this process for a specified number
of cycles. The voltage during the charge/discharge cycle
are measured, the capacity during the discharge cycle is
measured, and optionally the current of the charge cycle
is measured.
Dynamic
Similar to a discharge test, but the software GUI (graphical
user interface) allows the user to change current draw
without having to stop and start a new test.
Internal
Runs a quick test to measure the internal resistance
of the battery. This is done by measuring the terminal
voltage and voltage under the specified test load, then
calculating the internal resistance by performing a
voltage divider calculation with the CBA’s resistance.
WARNING:
Never hook the CBA to a battery that has something else connected and that is not totally ground
isolated. To test a charge in the charge monitor mode, the charger must be totally electrically isolated from the
computer ground.
