1.2.2.1 Battery charging ...
... on mains supply
living-area battery
:
control system * thyristor controller
charging characteristic * IWUoU
charging current * 10A arithmetic mean or 15A eff at 230V mains supply and 12.0V
charging voltage. The charging current is mains supply dependent.
maximum charging voltage * 14.4V
float voltage * 13.8V, automatic change-over
new charging cycle,
change-over to boost-charge * when battery voltage is about < 13.8V
IW boost-charge at max 10A arithmetic
mean, electronically limited, up to
maximum charging voltage
Uo then equalize-charge at constant 14.4V
selectable: 20 minutes duration for lead-
acid, 6h duration for lead-gel batteries
U then automatic change-over to float-
charge at 13.8V
If due to high loads the float voltage of 13.8V cannot be provided, the battery charger switches over
from float to boost-charge.
safety circuits * short-circuit and reverse-polarity protected,
charger needs a connected battery with a voltage of > 2.5V
* safety fuse in mains circuit, 1.6A slow
* over-temperature switch in transformer
starter battery:
charging current * trickle-charge to starter battery with max 2A
... while driving
charging current * simultaneous charging of starter and living-area battery by alternator,
batteries in parallel by cut-off relay, maximum charging current into the
living-area battery must not exceed 30A, see block diagram.
1.2.2.2 Battery Monitor Module
switch-off voltage * approx 10.5V
minimum reset voltage
for 12V main-switch on
instrument panel * approx 11.0V
