Charging Curve - Cristec YPOWER Série Manuel D'utilisation

3.3.5 Charging curve

BOOST in ON position
With this setting the YPOWER shore power unit delivers a 5-step charge curve IUoU + automatic weekly recycling
(switch E) + return to automatic BOOST : BOOST, ABSORPTION, FLOATING + REFRESH, REBOOST.
V BOOST: BOOST voltage (see table above)
V FLOAT: FLOATING voltage (see table above: voltage with no BOOST)
T BOOST: BOOST maximum duration (see table above – paragraph 3.3.2)
T ABS: ABSORPTION maximum duration (see table above – paragraph 3.3.2)
BOOST phase:
Starts up automatically when the charger is turned on if the battery is flat. The current is then at maximum output.
ABSORPTION phase:
Begins when the voltage has reached the maximum BOOST level. The current level starts falling.
These two phases combined last a maximum of TBOOST+TABS (depending on setting). If the current falls below 20% of
rated current, the FLOATING phase automatically kicks in. Duration and current intensity depend on how charged the
battery is.
FLOATING phase:
Starts after TBOOST or if output current has reached 20% of the charger's rated current. The voltage switches to the
FLOATING value and the rated current continues to drop.
