Aerosol Automatic Fire Protection For Changing and Charging Storage
Batteries
Introduction of electric powered vehicles
In trading and industrial activities, electric powered vehicles
such as fork lift trucks and pallet trucks (industrial trucks) or
mechanical sweepers (cleaning equipment) are powered by accumulator
batteries. To maintain the operational readiness of these vehicles,
the accumulator batteries - referred to as batteries below - must
be charged at regular intervals and maintained appropriately.
Why fires happen in charging storage batteries?
Although developments in recent years have seen more efficient and
lightweight batteries available (e.g. lithiumion), electric powered
vehicles normally use lead acid batteries. The electrolyte used in
these batteries is diluted sulphuric acid. During the charging and
discharging processes, the battery electrodes produce hydrogen gas
and other by-products. This creates a potential explosion hazard
which increases if the ventilation is insufficient or poorly
designed.
Meanwhile the chargers for industrial trucks and cleaning equipment
and electric road vehicles also needed protection.
How to choose the fire extinguisher?
- FireLess 0.3 aerosol fire extinguishing device was adopted, the
dose of each fire extinguishing device was 0.01kg, and the
discharging time of the fire extinguishing device was less than
20s.
- If you need a warning device to feedback the fire signal to the
driver, you can also equipped with CSIC1161(Fireless 0.5 sensor).
This fire warning and extinguishing device has the function of
early warning of battery fire. Before the battery open fire is
generated, it sends out early warning signals to the man-machine
interface (button/monitoring interface) in the driver area.
CSIC1161(Fireless 0.5 sensor)fire warning and fire extinguishing
device has the function of automatically starting the fire
extinguishing device. It can automatically start the fire
extinguishing device to extinguish the fire in case of a lithium
battery fire. At the same time, the man-machine interface
(button/monitoring software) in the driver area receives the
feedback signal of automatically starting the fire extinguishing
device.

Risks in battery that cause fires:
Fires in battery charging installations are usually attributable to
technical deficiencies in the electrical equipment and to failure
to observe safety measures.
Examples include:
• combustible materials stored or dumped in the immediate
surroundings;
• lack of servicing and maintenance leading to:
– increased contact resistance and degradation of insulation on
connectors and charge cables respectively;
– soiling and debris build up within the machine causing
overheating;
• insufficient ventilation;
• overload of the power outlet;
• missing or insufficient collision/impact protection.
