Hawker electrolyte circulation system (optional accessory)
®
1. Application
The electrolyte circulation system is based on the principle
of pumping air into the individual battery cells. This system
prevents electrolyte stratification and the battery charge
is optimised using a charge factor of 1.07. The electrolyte
circulation is particularly beneficial for heavy duty use, short
charge times, boost or opportunity charging and in high
ambient temperatures.
2. Function
The Hawker electrolyte circulation consists of a pipe system
fitted in the cells. A Hawker Aeromatic diaphragm pump is
fitted in the charger or separately mounted on the battery or
vehicle. This diaphragm pump sends a low rate airflow into
each cell which creates a circulating air stream inside the cell
box.
The air stream is continuous or pulsed depending on the
battery voltage and pump type. The air supply is adjusted in
accordance to the number of cells in the battery.
The pipe system to the individual battery cells must follow
the existing electrical circuit. This reduces the risk of current
leakage in the presence of electrolytic gas causing an
explosion (EN 62485-3).
Wi-iQ (optional accessory)
®
Wi-iQ – the elevtronic device – will provide indications
according to the table below.
Tricolour LED
Green blinking = hardware OK
Blue rapid blinking = wireless identification
Red blinking = temperature warning > 55° C
Blue LED
Rapid blinking = wireless identification
Slow blinking = voltage balance warning
OFF - Flashing = electrolyte level is OK
Light is constantly on =
electrolyte level is low - please top up
The Wi-iQ is the electronic device that communicates
wirelessly to download the battery key information for better
diagnostics & service. The device is fitted to a main DC cable
on the battery to monitor and record data of current, voltage,
temperature and electrolyte level (via optional external
sensor). The LEDs on the Wi-iQ provide real time status of
battery's condition.
The information is transferred to the PC via USB by Wireless
communication.
Tricolour LED Blue LED
2.1 Use with separate pipe system
Air is supplied when the charger pipe system is connected to
the battery pipe system (with blue ring).
2.2 Use with automatic connection of the pipe system
Connecting the charge plug with integrated air supply auto-
matically supplies air to the battery.
2.3 Maintenance of air filter
Depending on the working conditions, the pump air filter
should be changed at least once a year. In work areas with
high levels of air-pollution, the filter should be checked and
replaced more frequently.
2.4 Repair and maintenance
The system must be checked for leakage. The Hawker charger
will display an error message to indicate leakage. Sometimes
in the case of leakage the characteristic charging curve is
switched over to the characteristic standard curve (without
electrolyte mixing).
Faulty parts and faulty pipe sections must be replaced.
Only Hawker original spare parts may be used, as these are
designed for the pump air supply and will ensure correct
functioning of the pump.
1. Operation
The Wi-iQ is suitable for use on all battery technologies
Voltage range is 24V – 80V.
The device records global data during the life of the battery.
It will store data for 2,555 cycles (complete history stored by
PC). The data can be analysed by the PC software program:
state of charge, temperature warnings and low electrolyte
level warnings.
2. Clear visibility
Selecting the Exception & Detailed Reports will provide
information on the condition of your battery and any actions
that are necessary. Wi-iQ Report will quickly enable you to
get a handle on your battery fleet charging & discharging
characteristics. With information by battery family (truck
type) you can see depth of discharge charts, cycles, charging
and much more.
3. Very easy to use
Plug in USB modem to the PC, scan the Wi-iQ and up-load
the data. Wi-iQ Report is a PC Software running on Windows
7, 8, XP or Vista. A USB wireless key is used for downloading
Wi-iQ data in to a SQL database.
