The Titan battery charger

The Titan battery charger is a fully automatic charger for 12V, 24V or 48V batteries and is
powered by a mains voltage of 230Vac, 50Hz or 110Vac, 50 Hz for the Skylla-Tg 24/30
110V. It charges the battery according to the IUoUo characteristic, which is a 3-stage
charging characteristic. This characteristic is shown in illustration 1. While charging, the
Titan continuously measures the battery voltage and current and bases the charging voltage
and current on the measured values.

Assuming that the battery is discharged, the Titan charger starts charging in the boost-charge
mode. In this mode the battery is charged until the battery voltage reaches the boost voltage.
At this point the battery is charged to approximately 80% of its maximum capacity. This is the
end of the boost-charge mode and the Titan charger automatically switches to the equalize-
charge mode.
During the equalize-charge mode the charging voltage stays the same as the boost voltage but
the charge current slowly decreases. The duration of this mode is pre-selectable to 4, 8 or 12
hours. The standard time of the equalize-mode is 4 hours. After this time the Titan charger
automatically switches into the float-charge mode.
In the float-charge mode the charge voltage changes into the float voltage and the charge
current continues to decrease. This mode lasts for 20 hours.
After the float-charge mode the charger returns to the equalize-charge mode for 30 minutes,
this is to compensate for the normal leakage or self discharge of the battery.
