8.3.2 Energy balance of the living area battery
The living area battery has a limited power supply only. For this reason, the
electrical appliances should not be operated without a 240 V power supply for
a longer period of time.
Below, the calculation of the maximum operating time of the currently available
battery capacity is described.
„
Record the daily requirement. Note the switching on times and the power
output of the devices used (see table below).
Example: In the morning, three spotlights with 10 watts [W] each are lit in the bathroom
for 30 minutes.
„
Convert the power data into the required capacity in accordance with the
following formulas:
Power consumption [W] : 12 [V] = Current [A]
Current [A] x Operating time [h] = Capacity [Ah]
Example: 30 [W] : 12 [V] = 2.5 [A]
2.5 [A] x 0.5 [h] = 1.25 [Ah]
The table for a whole day could look like this:
„
Calculate the maximum effective energy with the following formula or
determine it with a special indicator unit:
Current capacity [Ah] : Deep discharge protection = Maximum effective
energy [Ah]
Example: 80 Ah : 1.3 (gel battery) = 61.5 Ah
„
Calculate the maximum operating time in accordance with the following for-
mula:
Max. effective energy [Ah] : Daily requirement [Ah] = Max. operating time
(in days)
Z
The example calculation refers to a new, optimally charged battery. The
actual effective battery capacity depends on the current charging condition
and the age of the battery. The current battery capacity can be determined
by means of special indicator units.
