GLOSSARY
Charging Profile
The charging profile defines the rate of current charge over time. The charger adapts to the
battery’s age and level of discharge. Controlling the overcharge coefficient, whatever the
battery’s discharge level, reduces the amount of electricity consumed.
Cold Storage Profile
This is a charging profile that allows the configuration of the charger for use with batteries in cold
storage application. The profile is an IEI (constant current, constant voltage, constant current)
type with a number of user configurable parameters.
Gel-Bloc Profile
This charging profile is an IEI (constant current, constant voltage, constant current) charging
profile designed for gelled electrolyte type sealed lead acid batteries.
NXBLOC Profile
This charging profile allows charging of NexSys TPPL bloc batteries at rates of 0.2 to 0.7 C
6.
NXSTND Profile
This charging profile allows charging of NexSys 2V batteries at rates of 0.20 to 0.25 C
6
.
Opportunity Profile
This charging profile is used when opportunity charging is desired. It includes a start rate of up
to 25% of the battery’s 6-hour rated amp hour capacity and requires an equalize charge
performed once a week. The weekly equalize charge can be programmed to run automatically.
Operation
During opportunity charging the user can charge the battery during breaks, lunch or any
available time during the work day. The Opportunity Profile allows the battery to be
safely charged while it is kept in a partial state of charge between 20% and 80% of the
6-hour rated capacity during the work week. Sufficient time should be scheduled after
the weekly equalize charge to check and maintain electrolyte levels and allow the
battery to cool to ambient temperatures.
Daily Charge
When using the Opportunity Profile, the Daily Charge option can be set to add
additional charging time every day if the work schedule allows. This option should be
considered only when the daily work demand requires additional capacity.
STD Flooded (IEI) Profile
The profile is an IEI (constant current, constant voltage, constant current) type with a number of
user configurable parameters.
VRLA Profile
This charging profile allows for valve regulated lead acid batteries to be charged. This charging
profile is an IEIE (constant current, constant voltage, constant current, constant voltage) type.
