3.2 – System Function
Charge Prole
The DVS provides a constant current–constant voltage–constant current (I-E-I) charge prole that precisely
controls the charge rate, and optimally charges the batteries by precisely adjusting the current in response to
the capacity, temperature, and age of the batteries.
Battery Monitor and Identier
The DVS works with a battery monitor and identier (BMID), which is a small monitoring device mounted on the
battery. The BMID enables the charger (power station) to adjust the charge automatically to match the requirements
of all of the batteries in the eet, eliminating mismatching batteries and chargers (power stations).
User Interface
The keypad and display on the front of the DVS (Figure 3) provide the user interface to the charger (power
station). The alphanumeric display panel constantly updates the charger (power station) and battery status, and
allows access into the programming menus through the keypad. Four status light-emitting diodes (LEDs) allow
the user to determine, from a distance, when the charge is in progress; at 80% complete, fully charged, or in
equalization. A Fault/Warning LED serves to alert the user to fault conditions.
