Storage
IEI (constant current, constant voltage, constant
current) type with several user configurable
parameters specifically designed for cold
storage applications.
GGel-Bloc
IEI (constant current, constant voltage, constant
current) charging profile designed for gelled
electrolyte type sealed lead acid batteries.
IIONIC™
The IONIC™ charge profile diagnoses the
battery status throughout the recharge phase
and adjusts its parameters to optimize the
charge of flooded battery technology. Short
current pulses injected during charge stimulate
gas formation in the active material, allowing
for a better density distribution of sulfuric acid
(homogenization) across the surface of the
plates. Being performed during the regular
charge, this sophisticated form of equalization
improves charge efficiency in terms of charge
time reduction and heat generation.
LI LITH
When a NexSys®iON Li-ion battery is
connected, the CAN communication between
the battery and charger is established and the
message “BMS CONNECTED” will be displayed
on the screen. The battery BMS will control the
charge current and voltage through the CAN.

5.4. Start charging
When a battery is connected to the charger, the control board senses the
voltage and after a short delay, the charger starts charging the battery
automatically if auto start is set to ON. Push the Stop/Start button if the
battery is already connected. When charging a NexSys iON battery, the
CAN communication between the battery and charger is established
and the message “BMS CONNECTED” will be displayed on the screen.
After few seconds, the battery will close the charge contactor to initiate
the charge. The charger will start the countdown process and will start
displaying the charge information.
5.4.2. Without a Wi-iQ®Device: If the Wi-iQ device adapter is not enabled
or no Wi-iQ devices are in range, effective charging starts after
the programmed delay. The charger uses Profile, Capacity and
Temperature settings programmed in the Configuration menu.
5.4.3. PAIRING with a Wi-iQ Device: If one or more Wi-iQ device adapters
are in range, the charger will turn on and apply current to the battery.
The display will show “SCAN” followed by “IQLINK”. This routine
determines which Wi-iQ device in range is connected to the battery
charger. Once the charger makes the determination, it downloads
data from Wi-iQ device, displays the battery S/N, updates the profile
capacity, and temperature for charging, and starts the main charge.
5.4.4. Charging current (2) is determined by the battery voltage and state
of the charge condition. Charging current declines automatically as
battery voltage rises during the charge. As the battery charges, the
graphical display will output various charge parameters including
the percentage of battery capacity (6).
When charging a NexSys iON battery, the battery BMS controls
the charge current and voltage. During the charge cycle, the BMS
through the CAN will send information to the charger to start,
stop and output the desired current and voltage. If the CAN is lost
during charge cycle, the charger will stop the charge and show the
off-charge display without the message “BMS CONNECTED”.
5.4.1. Delayed Start: If the charger was programmed for delayed start,
charging will begin following that delay. When the battery is
plugged in to the charger, the display shows the time remaining
before the programmed charging starts.
