Curtis 1310 User Manual

Individual parameters are presented as follows in the menu charts:
Battery Discharge Indicator algorithm
The 1310 contains a sophisticated battery state of charge algorithm. Setup properly, this
algorithm can track the remaining battery charge (in percent) using only a voltage reading from
the B+ Power tab (or J1-24). To achieve any accuracy, it is critical to set the BDI parameters
correctly for the vehicle, battery and normal duty cycle of the application. Note that many of the
parameters are in volts per cell. A normal 24 volt battery has 12 cells.
The remaining battery capacity is automatically updated into the value named;
BDI_Percentage
There are 6 parameters that set up the tracking algorithm;
BDI PARAMETERS
Nominal Voltage
Nominal_Voltage
24 – 48v
1536 - 3072
Must be set to the systems nominal battery voltage. This is
used by the 1310 to determine the number of cells in the
pack for the BDI parameters below.
BDI Reset Volts Per Cell
BDI_Reset_Volts_Per_Cell
0.00 – 3.00v
0 - 3000
At power on, The BDI is reset to 100% if the battery is
measured above this setting. Typical value is 2.09v. Reset
Volts must be set above Full Volts.
BDI Full Volts Per Cell
BDI_Full_Volts_Per_Cell
0.00 – 3.00v
0 - 3000
The BDI will output a 100%, full, while the average voltage
per cell reading is above this setting.
BDI Empty Volts Per Cell
BDI_Empty_Volts_Per_Cell
0.00 – 3.00v
0 - 3000
The BDI will output a 0%, empty, when the average voltage
per cell reading is below this setting.
BDI Discharge Time
BDI_Discharge_Time
0 – 600 min
0 - 600
The time it will take the BDI to go from 100% to 0% at
maximum current draw.
BDI Reset Percent
BDI_Reset_Percent
0 - 100%
0 - 100
If the previous BDI % value was above this point at power up,
the BDI will NOT reset, even if the battery is measured above
the Reset Volts level. This will prevent a slightly discharged
battery from “floating” and reseting the BDI at every power
up.
