ABSORPTION
CHARGE
With battery voltage equal to Vmax (Maximum
voltage of the selected charging curve), will be
delivered a costant voltage equal to the
selected curve Vmax. The delivered current will
decrease as the battery state of charge
increases till about 3A. Timeout 6 hours.
DESULPHATION
An approximately 2A constant current will be
delivered, allowing the battery voltage to rise
independently to the maximum value of 15.8V.
This phase ends to the achievement of 15.8V.
Timeout 2 hours.
MAINTENANCE
This phase keep a constant voltage related to
the selected charging curve (Vmaint). This phase
has a 4 hours timeout for the LiFePO
4
charging
curve with maintenance ON (curve N°7), while
for the other curves there’s no time limit. If
during the maintenance phase the voltage
should fall below 13.15V for LiFePO
4
curve and
12.65V Wet curve and 12.8V and for the other
curves, charge will be restarted from the first
phase. Timeout 4 hours.
B2 - PHASE DISCUSSION
PULSE CHARGE
With voltage between 8V and 10.5V, a variable
current between 1A and 2A, every 5 seconds.
Timeout 4 hours.
RECONDITIONING
With voltage between 10.5V and 12.0V, an
approximately 2A costant current will be delivered.
Timeout 8 hours.
BULK CHARGE
With battery voltage between 12V and 14,4V,
will be delivered a 5A constant current.
ABSORPTION
CHARGE
With battery voltage 14,4V will be delivered a
14,4V constant voltage. The delivered current will
decrease as the battery state of charge increases
till about 3A. Timeout 6 hours.
MAINTENANCE
This phase keep a constant voltage of 13,5V.
Timeout 8 hours.
