BATTERY CONSUMPTION:
In these systems, batteries are used as components that energy is stored in during periods of time when
electricity supply is available from the mains. Then, if there is a failure in this supply, the batteries are
responsible for providing power to the connected components, allowing the system to run autonomously until
they are empty.
From an ideal point of view, it could be said that the battery should not consume power in standby (fully
charged and floating or when the device is completely switched off).
However, several modes of operation can be established for the batteries, in which they will be consuming or
supplying energy:
10.2.1
CHARGING MODE:
When AC input is present, the battery can be considered as another device that consumes energy. During
the constant voltage charging phase, the battery will be charged up to its rated capacity, whereas in
floating, the internal losses due to self-discharge will be compensated.
-During constant voltage charging (quick charging), the maximum charging current is limited to the
value set in the charger. The time spent in this charging period and the consumption will depend on
the level to which the battery has been discharged.
-The battery is considered charged when the charging current drops below a specific threshold that is
set in the charger. The batteries will then be kept at a floating voltage.
-Sometimes, when batteries are nearing the end of their useful life, their internal leakage current can
increase above the threshold value for going into float. To prevent constant voltage charging from
continuing indefinitely, a maximum constant voltage charging time is defined in the charger, after
which the charger switches to the floating state.
