4. Absorption time determined by tail current
In some applications it may be preferable to terminate
absorption time based on tail current only. This can be
achieved by increasing the default absorption time multiplier.
(warning: the tail current of lead-acid batteries does not
decrease to zero when the batteries are fully charged, and this
"remaining" tail current can increase substantially when the
batteries age)
Default setting, LiFePO4 batteries
LiFePO4 batteries do not need to be fully charged to prevent
premature failure.
The default absorption voltage setting is 14,2V (28,4V).
And the default absorption time setting is 2 hours.
Default float setting: 13,2V (26,4V).
These settings are adjustable.
Reset of the charge algorithm:
The default setting for restarting the charge cycle is
Vbatt < (Vfloat – 0,4V) for lead-acid, and Vbatt < (Vfloat – 0,1V)
for LiFePO4 batteries, during 1 minute.
(values for 12V batteries, multiply by two for 24V)
3.8 Automatic equalization
Automatic equalization is default set to 'OFF'. With the Victron
Connect app (see sect 1.12) this setting can be configured with a
number between 1 (every day) and 250 (once every 250 days).
When automatic equalization is active, the absorption charge will
be followed by a voltage limited constant current period. The
current is limited to 8% or 25% of the bulk current (see table in
sect. 3.5). The bulk current is the rated charger current unless a
lower maximum current setting has been chosen.
When using a setting with 8% current limit, automatic equalization
ends when the voltage limit has been reached, or after 1 hour,
whichever comes first.
Other settings: automatic equalization ends after 4 hours.
When automatic equalization is not completely finished within one
day, it will not resume the next day, the next equalization session
will take place as determined by the day interval.
