9.7.1 Program 621: Deep Discharge NiCd battery HAWKER
Name according to manual: Deep Discharge with Cell shorting for HAWKER with C
1
21: NiCd battery HAWKER
select Batteryprocessing:
P6: Deep Discharge
Enter:
Number of cells
Rated capacity
Step 1:
Discharging with C
1
until a voltage of 1 V for each cell is reached.
In case no automatic cell tester is connected:
After 48 minutes a signal requests the measurement of the single cells voltages.
Otherwise: Cell measurement takes place automatically
Continue with discharging with C
1
until the voltage of 1 V multiplied by the number of interconnected
cells is reached.
Step 2:
Afterwards discharging with C
10
until a voltage of 0.5 V for each cell is reached.
The connection of an automatic cell scan adapter is required
Step 3:
Deep discharging with device integrated 1 Ohm resistors over each cell for 24 hours.
End of program
Example:
Connected is a 24 V battery with mit 40 Ah.
The battery at first will be discharged with 40 A to 20 V. Afterwards discharging with 4 A to 10 V.
After that 1 Ohm resistors will be shifted over the cells.
Time monitoring:
Discharging with C
1
maximum 90 minutes, discharging with C
10
maximum 180 minutes.
