To bypass the fast charge and start an equalization charge on a battery pack at any state of
charge, press and hold the “Equalize” button for three (3) seconds, the equalize light will
illuminate without flashing, and the charger will start a full equalization on the pack without a
fast charge. To cancel a requested equalization charge, press the Equalize button and the
Equalize LED will turn off.
CAUTION
Always run a full equalization charge
prior
to a fast charge on any
battery pack that has had a cell replaced to ensure the pack is
balanced.
5.4 Full / Over Charging
Full/Over Charging is a feature that allows the user to schedule a period of fast charge to 100%,
followed by a brief EQ-like period outside of the normal EQ window. This feature ensures the
battery is maintained for peak performance. The Over Charge feature resembles the
Equalization procedure in that Over Charging utilizes the Finish Current setting of Equalization.
If the vehicle is connected to the charger during the time window set by the user, and the feature
is enabled, Full/Over Charging will be performed automatically. The time window, as well as
the length of Over Charging, is set through the “Full/Over Charge Setup” submenu of the
“Charger Configuration” menu.
5.5 Reduced Charging
Reduced Charging allows the user to reduce power consumption during peak-rate periods. The
feature limits the output current to a predetermine rate during a user defined time window. The
current, as well as the time window, is set through the “Reduced Charge Rate Setup” Submenu
of the “Charger Configuration” menu. If the charger is actively charging during the time
window, and the feature is enabled, the charging current will be reduced to the user-selected
value. The current will remain at this level as long as the charge is within the specified window.
5.6 Viewing Charge Data or Fault / Warning Screens
While charging, the display screen is periodically updated with the latest charging data
including voltage, current, battery temperature, and battery state of charge. If there is a fault or
warning, the fault or warning message will be displayed instead.
Charging data
This screen displays the voltage, current, state of charge, and temperature of the battery. During
a charge, the screen will say "Charging" and the data will be updated periodically. See Figure
5.6.
