Starter battery charging process (battery I) –
Parallel circuit
Driving operation
During driving operation, the starter battery (battery I) is
charged by the generator of the vehicle. As long as the gen-
erator is running and the voltage of the starter battery goes
above 13.7 V, the supply battery and the starter battery oper-
ate in parallel. The supply battery is now charged by the gen-
erator. If the voltage of the starter battery drops below 13.2 V,
the parallel circuit is disconnected again.
Mains operation
(all voltage values with respect to a battery temperature of 20 °C)
When connecting to the mains of 230 V, the supply battery
is charged first. Once the supply battery reaches a voltage of
14,1 V, it is switched in parallel with the starter battery. If the
charging current rises to its rated value due to a user and the
battery voltage falls below 13.2 V, then the parallel connection
is automatically disconnected. The starter battery thus always
remains ready to start.

Charging process
Automatic
Automatic switching (Bulk phase)
OFF when battery voltage reached 14.4 V,
charging current < 14.5 A.
Automatic switching (Absorption phase)
Ten hours at a constant 14.4 V for gel or AGM batteries.
Four hours at a constant 14.4 V for liquid electrolyte batteries.
Automatic switching (Float phase)
Float phase, constant at 13.8 V
Temperature dependent control (optional)
The values of the automatic switching refer to a battery
temperature of 20 °C. When using a temperature sensor at
the battery II, these values vary as a function of the battery
temperature.
High temperature –> Lowering of the threshold values.
Low temperature –> Higher threshold values.
Application
Parallel operation, buffer operation, general charging
operation.
