Charging characteristics
The charging characteristics are referred to as modified IU0U characteristics.
U/V
I/A
I Phase
The empty battery is charged with a constant current at the beginning of the
charging process, until the battery voltage reaches 13.8 V or 27.6 V. The
charging current falls slowly when the battery has reached this charging lev-
el. If the current falls below the 80% mark, the charger switches to the higher
charging voltage of 14.4 V/14.8 V or 28.8 V/29.6 V.
Note
I
The charging voltage and the time for the main charging phase
(U0 phase) can be selected by means of a switch panel (see chap-
ter "Setting the IU0U automatic charger (fig. 8, page 7)" on
page 48).
U0 Phase
Now the time that limits the main charging phase (U0 phase) to a maximum
of 8/16 hours is recorded. When the charging voltage is switched over, the
current is increased until the maximum is reached. It remains constant as
long as the battery voltage is below 14.4 V/14.8 V or 28.8 V or 29.6 V.
When the maximum voltage is established, the current drops again. The volt-
age remains constant (U0). During this main charging phase, which is limited
to 8/16 hours, the battery is charge completely.
