Scheduled Battery Characterization
Use the following procedure to schedule regular
Battery Characterization
discharges.
Each Battery Characterization discharge will update the characterization data and ensure the
Battery Time Remaining value is as accurate as possible.
1
Check that all battery parameters are set to the correct values. See Batteries Configuration
on page
2
Enable
Battery Current Limit
(see details on page
3
Check that the load current is at least 2% of the C10 capacity of the batteries (
Battery
Capacity
) and 150% of the
Battery State Threshold
. See Batteries Configuration on page
If the load current is less than 10% of the C10 capacity of the batteries, then Battery
Characterization will take longer than 10 hours.
4
In DCTools go to:
Control Processes
>
Battery Characterization
. Set the following parameters:
Battery Characterization
Enable:
Enabled
End Voltage:
Set to the voltage per cell when the battery is regarded
as fully discharged.
In general, use the same value as for the
LVD Disconnect
Voltage
(see LVD Configuration on page
).
End Voltage
must be at least 0.02V/Cell above the
Minimum System
Voltage
per cell.
The Minimum System Voltage is viewable in DCTools
at Control Processes > Voltage Control. It is not
configurable.
Interval:
Set to the required interval between scheduled
characterizations (at least 90 days to avoid excessive
battery cycling). Or, set to zero if only manual
characterizations are required.
Lockout:
Set to the period when a characterization will be
inhibited, after an ac supply failure.
During any subsequent battery discharge the SC100 will display an estimate of the
Battery Time
Remaining
and the
State of Charge
(SOC). See Battery Time Remaining on page
Input/Output (I/O)
The following section describes the I/O functions available with a single IOBGP I/O board.
Additional SiteSure-3G input/output (I/O) modules or IOBGP I/O boards cannot be connected to
the SC100.
