5.2. Charge operation
5.2.1. Charger idle display:
With the charger in wait mode (no battery
connected) and without pressing the Stop/Start button, the display
will show the following information:
5.2.2. Connect battery:
Make sure the charger connector(s) matches the
battery connector(s). Plug the charger connector(s) to the battery
connector(s). For chargers with dual connectors, both connectors
must be connected in order to start a charge.
5.2.3.
NexSys
®
iON Li-ion batteries come with specific type of connector.
The NexSys
®
+ charger comes with one or two connectors (LI
Connector) depending on the charger model. When the charger is
equipped with two connectors, both connectors must be connected,
otherwise charge cycle will not start. Always connect connector 1
first. All NexSys
®
iON charger connectors are equipped with arcless
option called Late Make Early Break to prevent arcing if battery is
disconnected while charging.
5.2.4.
When CAN communication is established between the NexSys
®
iON
battery and charger, “BMS CONNECTED” will appear on the display
screen. If the text “BMS CONNECTED” is NOT shown, the charge
cycle will not start. Check CAN wiring and battery.

iON Batteries
5.4.2. Without a Wi-iQ
®
battery monitoring device
: If the Wi-iQ
®
battery
monitoring device adapter is not enabled or no Wi-iQ
®
battery
monitoring 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
®
battery monitoring device
: If one or more Wi-
iQ
®
battery monitoring 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
®
battery
monitoring device in range is connected to the battery charger. Once
the charger makes the determination, it downloads data from Wi-iQ
®
battery monitoring 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
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.
5.4.1. 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.
