DVS Fast Charging System

5.5 Full / Over Charging

Full/Over Charging is a feature that allows the user to fully charge a battery to 100% and then
Over Charge the battery for a predetermined period of time. This feature resembles the
Equalization procedure in that Over Charging utilizes the Finish Current setting of Equalization.
However, this feature enables the user to set a time window when Full/Over Charge can take
place. It also allows the user to control the length of time that the battery is Over Charged. If
the charger is actively charging during the time window set by the user, and the feature is
enabled, Full/Over Charging will be performed. 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.

5.6 Reduced Charging

Reduced Charging allows the user to set a predetermined rate of current during a user defined
time window. The current, as sell 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.

5.7 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 5.5.
