Battery charging function
A main charging cycle of the starting battery and the house battery is initiated in the following situations:
• After a standstill of the alternator
• After falling below the reset voltage
Fig.
on page 3
In all charging phases almost the entire possible charger current is available for the additional supply of DC loads
without discharging the battery.
The charging characteristics for fully automated continuous operation without monitoring are referred to as IUOU
characteristics.
1: Pulse charge
With a voltage between 8 V and 10.5 V, a current between 1 A and 2 A will be delivered every 5 s (timeout 4 h).
2: Reconditioning
With a voltage between 10.5 V and 12 V, an approx. 2 A current will be delivered (timeout 8 h).
3: Bulk charge
House battery (B1): With a voltage between 12 V and V
constant current will be delivered depending on the model:
• SCE320, SCE320B: 20 A
• SCE360, SCE360B: 25 A
Starting battery (B2): With battery voltage between 12 V and 14.4 V, a constant current of a 5 A will be delivered .
