Information
The following information is available about Battery Characterization.
Parameter
Description
Where to find:
State
Locked Out: A characterization cannot start. See Lock
Out Remaining (below).
Inoperative: Battery characterization data is not
loaded, End Voltage is below the characterization end
point, or the bus voltage or battery current is
unavailable.
Inactive: Battery Charge State is Floating or Charge .
 See Battery Charge State on page 36.
Active: The battery is being characterized.
DCTools: Control Process >
Battery Characterization
Maximum
Remaining Time
The maximum time to the end of the currently active
Battery Characterization.
 This value is not available for the initial
characterization.
Lockout Remaining
The time remaining until a Battery Characterization can
be started (after the last ac power fail). Set by the
Lockout period.
Count Down
The time to the start of the next scheduled Battery
Characterization.
 This value is N/A when a characterization is in
progress or Battery Characterization is
Disbaled.
Offset Voltage
The adjustment to the bus voltage being applied due to
the Battery Characterization. While a Battery
Characterization is running, the rectifiers are turned
down to force the battery to carry the load.
Initial Characterization
Use the following procedure to characterize a battery for the first time.
 This will provide the most accurate characterization data. However, if the characterization data
from a battery of the same size and type is available, then this can be added to the Battery
Characterization Table manually. The following characterization is then not required.

 It will take at least 10 hours to characterize a battery.
 During a Battery Characterization the bus voltage will gradually reduce to the battery end
voltage. Ensure that this will not affect the operation of any equipment connected to the dc
power system.
1 Check that all battery strings are connected and any LVD contactors are connected.
 During a battery characterization, LVD contactor disconnection is inhibited. If any LVD
contactor is configured to connect during a battery discharge then set it to Manual Connect to
prevent operation during the battery characterization.
