When the Automatic equalization cycle has initiated, the charger applies an equalization voltage to the battery as long as the
current level stays below the equalization current percentage setting of the bulk current.
Duration of the Automatic equalization cycle
In the case of all VRLA batteries and some flooded batteries (algorithm number 0, 1, 2 and 3) automatic equalization ends when
the voltage limit (maxV) has been reached, or after a period equal to (absorption time/8) - whichever comes first.
For all tubular plate batteries (algorithm numbers 4, 5 & 6); and also for the user-defined battery type, automatic equalization will
end after a period equal to (absorption time/2).
For the Lithium battery type (algorithm number 7), equalization is not available.
When an automatic equalization cycle is not completed in one day, it will not resume the next day. The next equalization session
will take place according to the interval set in the 'Auto Equalization' option.
The default battery type is a VRLA battery and any user-defined battery will behave as a tubular plate battery with regard to
equalization.
Equalisation stop mode
Set how the equalisation will end. There are two possibilities, first is if the battery voltage reaches the equalisation voltage and the
second is on fixed time, where the maximum equalisation duration is used.
Maximum equalisation duration
Set the maximum time that the equalisation phase will last.
Tail current
Set the current threshold that will be used to finish absorption phase before the maximum absorption time expires. When the
battery current gets below the tail current for one minute, the absorption phase will end. This setting can be disabled by setting it
to zero.
Temperature compensation
Many types of battery require a lower charge voltage in warm operating conditions, and a higher charge voltage in cold operating
conditions.
The configured coefficient is in mV per degree Celsius for the whole battery bank, not per cell. The base temperature for the
compensation is 25°C (77°F), as shown in the chart below.
