Low Battery Temperature Compensation is enabled,
temperatures monitored between this point and the Battery Low
Temperature Voltage Increase Threshold (A) will result in a
proportional increase of plant voltage to a level corresponding to
C*(D-A)*cells-per-string above the limit.
Battery Low Temperature Voltage Increase Threshold (A):
This is the lower temperature where, if Battery Low
Temperature Compensation is enabled, the temperature
compensating feature will have increased system voltage to a
level corresponding to C*(D-A)*cells-per-string above the FSP.
System voltage will be increased proportionally at any
temperature between this point and the Nominal Battery
Temperature (D) Slope.
Battery High Temperature Voltage Decrease Rate (Slope)
Per Cell (E): This is the slope rate for the voltage decrease per
cell when the battery temperature is above the Nominal Battery
Temperature (D) Slope.
Battery Low Temperature Voltage Increase Rate (Slope) Per
Cell (C): This is the slope rate for the voltage increase per cell
when the battery temperature is below the temperature at which
there is no voltage compensation (Nominal Temperature, D).
Battery Low Temperature Voltage Compensation Increase
Enable: This feature must be enabled in the appropriate
configuration menu in order to compensate at the lower
temperatures. This feature increases plant voltage rather than
decreasing it based on temperature. The capability to enable this
feature separately from high temperature compensation is
provided so that equipment loads sensitive to high voltages can
be protected.
Battery Temperature Compensation Enable: Battery
Temperature Compensation (slope thermal compensation) must
be configured to “enabled” in order for the feature to be active.
