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 electrolyte circulation consists of a pipe system fitted
in the cells. The 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).
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
automatically 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 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 circulation).
Faulty parts and faulty pipe sections must be replaced. Only
original spare parts may be used, as these are designed for
the pump air supply and will ensure correct functioning of
the pump.
Electrolyte circulation system
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 or to smartphone via USB or by wireless communication.
1. Operation
The Wi-iQ is suitable for use on all battery technologies.
Voltage range is 24V – 120V.
The device records global data during the life of the battery. It
will store data for 2555 cycles (complete history stored by PC).
The data can be analysed by Wi-iQ Report or E-Connect app,
depending on Wi-iQ version fitted to the battery.
2. Clear visibility
Selecting the Wi-iQ Report or E-Connect app will provide
information on the condition of your battery and any actions
that are necessary. Wi-iQ Report or E-Connect app 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.
See the Wi-iQ User Manual for further details.
