1.2.2.1 Battery charging ...
... on mains supply
living-area battery:
control system * thyristor controller
charging characteristic * IUoU
maximum charging voltage * 14.3V
charging current * 16A within mains supply range, electronically limited
floating voltage * 13.8V, automatic change-over
new charging cycle
(change-over to boost-charge) * if battery voltage approx < 13.8V, about 5 sec delay
3-phase characteristic:
* boost-charge at 16A
(arithmetic mean, electronically limited)
up to maximum charging voltage,
* then equalize-charge at constant 14.3V
(selectable: 1h duration for lead-acid;
8h duration for lead-gel batteries),
* then automatic change-over to float-charge
at 13.8V.
If due to high loads the 13.8V floating voltage can't be provided the battery charger switches
over from float to boost-charge after a delay of approx. 5 sec.
safety circuits * overheat protected
* overload protection by electronic current limiting
* short-circuit protected by a FK2 automotive fuse
starter battery:
charging current * trickle-charge of starter battery with max. 2A
...by solar regulator
max. allowed charging
current (camping battery) * 14A
...while driving
charging current * simultaneous charging of starter and living-area battery by alternator,
batteries in parallel by cut-off relay, maximum charging current of
living-area battery by alternator must not exceed 30A.
See block diagram.
