B1 - PHASE DISCUSSION
PULSE CHARGE
With voltage between 8V and 10.5V, a current
between 1A and 2A will be delivered, 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 voltage between 12V and Vmax (Maximum
voltage of the selected charging curve), will be
delivered a constant current of: 20A model
SC320M and 25A model SC350M.
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
(ONLY IF SELECTED)
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.
