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. The electrolyte circulation is particularly beneficial
for short charge times, boost or opportunity charging.
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 Fiamm Motive
Power 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
Fiamm Motive Power original spare parts may be used, as
these are designed for the pump air supply and will ensure
correct functioning of the pump.
