Kärcher BR 45/40 Service Manual page 90

During the I constant phase, the charger is
–
charged with the nominal current (see typeplate
on charger) and the charge voltage will increase
slower or faster depending on the charge condi-
tion. After that, the charger will switch to U con-
stant phase.
In the U constant phase, the voltage remains con-
–
stant and the current sinks continuously. After
that, the charger will switch to I constant phase.
In the I constant recharging phase, the voltage will
–
rise to the values indicated in the diagrams and
the current value remains constant. After that, the
charger will switch to maintenance charge.
The recharging phase serves to achieve the com-
–
plete transformation of the active mass in all cells.
During the maintenance charge, the fully charged
–
battery status remains at constant voltage. The
maintenance charge has no time limits.
