Description and main characteristics
1.3.2. Battery charge
Battery charge starts following absence of alternating
current voltage (AC) or after a battery test.
The battery charge process starts with fast charge state.
The charger establishes a voltage setpoint (v_carga) and
controls battery current to ensure it does not exceed
maximum charge current (i_lim). Current is lost as the
battery discharges.
It switches from fast charge state to floating for either of the
following two reasons:
1.
The maximum time set for fast charge state (tlim_carga)
is exceeded.
2.
The battery current drops below a set threshold (i_flot).
Once the battery current drops below a minimum threshold
(i_flot) or maximum time is exceeded (tlim_carga), it passes
to floating state. In this state the charger establishes the
battery float voltage (v_flot). Following a float time interval
(t
min
_flot), it is taken that the battery is completely charged.
The unit remains in floating state until there is an absence of
alternating current or a battery test starts.
The image below shows the typical charge process of a
battery.
In order to extend the working life of the battery, battery
voltage is compensated in accordance with temperature
in floating state. A parametrisable variable (comp_flot)
can be used to adjust the voltage to vary by each degree
centigrade.
The compensation range is limited between a maximum
and minimum temperature (comp_t
min
and comp_t
max
).
Temperature compensation (hab_comp) can also be
enabled in fast charge state, and there is a voltage variation
setting by degree (comp_carga). Enabling this option is only
recommended when a study indicates that it is required.

1.3.3. Battery discharge and disconnection
In the event of absence of alternating voltage, the batteries
keep the equipment supplied for a specific time interval. A
disconnection process starts if end of battery life is reached
and the alternating voltage input is not restored.
The following operation guidelines are followed in the
disconnection process:
• The unit detects that battery life reaches its end using a
parametrisable setting (desc_v_min)
• The "End of battery life" alarm is enabled at this moment.
• If the AC input is not restored after a few minutes on
standby, the unit disconnects the battery and both the
unit and the connected charges therefore go off.
Apart from the normal discharge process, there are two
other reasons for the battery disconnecting:
• Minimum battery voltage (desc_inm). If it drops below
this threshold, the battery disconnects instantaneously.
• Maximum battery voltage (desc_v_max). If this level is
exceeded, the battery disconnects for safety reasons.
