Charging Curve - Cristec HPOWER 12V/90A Manuel Utilisateur

3.4.5 Charging curve

BOOST in ON position
With this setting the HPOWER charger delivers a 5-step charge curve IUoU + automatic weekly recycling
(switch E) + return to automatic BOOST : BOOST, ABSORPTION, FLOATING + REFRESH, REBOOST.
V BOOST :

T BOOST :
T ABS :
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
2
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%
to the FLOATING value and the rated current continues to drop.
