BDI MENU
The source of the BDI percentage displayed by the 3301T can be either the 3301T's internal BDI
calculations or RPDO1. The parameters on the BDI menu are used for the internal calculations.

ACCESS LEVEL
DEFAULT VALUE
Field Intermediate
Specifies the battery's nominal voltage:
0
0 = 12/48/80V
1 = 24/60/96V
2 = 36/72V
The BDI algorithm requires that the nominal voltage
is correctly specified.
Field Intermediate
Specifies the battery cell voltage above which the
battery is considered charged.
2.350V
Charge Full must be at least 0.200V above
Charge Empty.
Field Intermediate
Specifies the battery cell voltage above which the
battery is considered as starting to charge.
2.100V
Charge Empty must be at least 0.200V below Charge
Full and at least 0.010V above Discharge Full.
Field Intermediate
Specifies the battery cell voltage at which the state
of charge is considered 100%.
2.040V
Discharge Full must be at least 0.120V more
than Discharge Empty and must be between the
following values:
• Charge Empty − 0.010V
• OCR Reset − 0.030V
Field Intermediate
Specifies the battery cell voltage at which the state
of charge is considered 0%.
1.730V
Discharge Empty must be at least 0.120V less than
Discharge Full.
Field Intermediate
Specifies the battery cell voltage above which the
BDI percentage is reset to 100%. OCR Reset is
2.090V
checked only once; the check occurs when the
3301T is powered up.
OCR Reset must be at least 0.030V above Discharge
Full and at least 0.010V less than Charge Empty.
Field Intermediate
Specifies the minimum time for the BDI algorithm to
decrease the BDI percentage from 100% to 0% or
30 minutes
increase the percentage from 0% to 100%.
Field Intermediate
Specifies the BDI percentage below which lift lockout
is activated.
10.0%
TPDO1 transmits the lift lockout status.
