Charging current distributor: ECL-76
Inverter: PerfectPower PP1002
The light system voltage UD+ is measured. If this voltage exceeds a variable voltage
value Ue (12.5 V – 14.0 V), the relay contact 30/87 (Batt. 2/Batt. 2) of the power relay is
closed. The starter battery and the additional battery are therefore connected in parallel
with low resistance and are charged together by the light system.
With UD+ > Ue, contact I2 is closed with I3. If the light system voltage falls below a
variable threshold value Ua (10.5 V – 12.5 V), due to an increased load because of the
air conditioner, relay contact 30/87 (Batt. 2/Batt. 2) is opened. Relay contact I2/I3 is also
opened.
This switches off the air conditioner compressor (the fan continues to run). The light
system now charges the starter battery (the fans consume little power). If the caravan has
a connecting cable between the two batteries, the additional battery is also charged.
If the charging voltage of the light system UD+ reaches the set voltage value Ue again,
the power relay and the control relay switch on again. The compressor motor starts again.
If the vehicle engine is not switched on (UD+ = 0 V) relay contact 30/87 (Batt. 2/Batt. 2)
is opened and relay contact I2/I3 is closed. The air conditioner can be operated and only
takes power from the additional battery. If the battery voltage falls below Ubatt = 10.5 V,
the inverter switches off.
