Modes of Operation
6.13.1 Mode A (Automatic)
In this mode, the charger charges the battery in conformity with a programmed charging profile. A charging profile
consists in turn of several charging stages in which each charging follows its own I / U profile. The I / U profile in
stage 1 is determined using the current level I
1
and the voltage level U
1
. The I / U profile in stage 2 is determined
using the current level I
2
and the voltage level U
2
.
Transition to the next charging stage occurs automatically if specific criteria are met (e.g. falling below a defined
charging current, charging of a specific charge quantity, the reaching of a fixed charging time etc.).
Charging example:
In stage 1 / phase I1, the battery is charged with a constant current I1 (if the voltage is < U1 and the charger
provides this current). The transition to phase U1 occurs if the defined voltage U1 is reached. Now the voltage is
constantly kept at U1 by reducing the charging current. This stage is referred to as
Main Charging.
