To determine the number of cells in the battery pack,
*
divide the Nominal Voltage setting (page 64) by the battery
chemistry's nominal volts-per-cell.
Lead Acid: 2.0 V/cell, nominal.
Other: Consult the manufacturer's data sheet.

RANGE
0.900 – 3.000 V The reset voltage level is checked only once, when KSI is first turned on.
Note that the BDI Reset Percent parameter also influences the algorithm
900 – 3000
that determines whether BDI Percentage is reset to 100%. Reset Volts Per
Cell should always be set higher than Full Volts Per Cell.
Reset Voltage Level = Reset Volts Per Cell × number of cells in the
battery pack.*
0.900 – 3.000 V The full voltage level sets the Keyswitch Voltage that is considered to be
100% state-of-charge; when a loaded battery drops below this voltage, it
900 – 3000
begins to lose charge. Keyswitch Voltage is viewable in the programmer's
»
Monitor Battery menu.
Full Voltage Level = Full Volts Per Cell × number of cells in the battery
pack.*
0.900 – 3.000 V The empty voltage level sets the Keyswitch Voltage that is considered
to be 0% state-of-charge.
900 – 3000
Empty Voltage Level = Empty Volts Per Cell × number of cells in the
battery pack.*
0 – 600 minutes Sets the minimum time for the BDI algorithm to count down the BDI
Percentage from 100% to 0%. The BDI algorithm integrates the time the
0 – 600
filtered keyswitch voltage is below the state of charge voltage level. When
that cumulative time exceeds the Discharge Time / 100, the BDI Percentage
is decremented by one percentage point and a new state of charge voltage
level is calculated.
State of Charge Level = ((Full Voltage Level - Empty Voltage Level)
× BDI Percentage / 100) + Empty Voltage Level.
0 – 100 % When a battery has a high BDI percentage, its float voltage at KSI On
can sometimes cause false resets. The BDI Reset Percent parameter
0 – 100
addresses this problem by allowing the user to define a BDI Percentage
value above which the BDI Percentage variable will not reset.
When KSI is first powered on, the BDI Percentage variable will reset
to 100% only if ((Keyswitch Voltage > Reset Voltage Level) and (BDI
Percentage < BDI Reset Percent)).
