Battery Manufacturer Now Offers ATEX Batteries
The ATEX Directive 94/9/EC was formulated to ensure that other people who are used in flammable and potentially explosive situations take more safety precautions. The battery powered equipment they inside these types of environments, such as lamps, gas detectors, and air-monitoring devices, have to match the highest safety principles. The batteries are often known as ATEX batteries or intrinsically safe power packs.
The ATEX safety directive identifies electric components that have built-in safety qualities formulated to protect people who are employed under dangerous conditions and places the duty on appliance manufacturers for developing and testing their devices to ensure which it incorporates the many necessary safety qualities.
There are numerous different technical design selections available to comply with the ATEX directive, such as explosion-proof enclosures, specific protection devices and encapsulation. This includes the pre-certification standard of 'Intrinsically Safe' (IS) components such as batteries that don't produce sparks and cannot release electrical or thermal energy may result in any form of reaction, even in case the component is abused (for example short circuited).
Rechargeable Lithium-Ion, NiCd, and lithium-thionyl chloride (Li-SOCl2) are associated with IS batteries. The creation of the ATEX Battery or Intrinsically safe Battery Pack is essential and a great number of aspects must be looked into in addition to environmental conditions, regarding life cycle, performance and weight.
For long life, Lithium-Ion ATEX Batteries offer unrivaled nominal capacities, probably probably the most superior attribute is planned to be able to pay and discharged over a wide temperature range, in particular at low temperatures.
The Li-ion Battery is a low upkeep battery, plus that most other chemistries cannot nation. There is no memory and no regular cycling is necessary to extend the battery's life. In addition, the self-discharge is less than fifty % compared to Nickel cadmium and Nickel metal hydride, therefore Li-ion well suited to modern day fuel gauge products.
Benefits and Limitations of Lithium-Ion Batteries.
a. Comparatively low self discharge, self-discharge is less than half that of Ni-Cd and Nimh.
b. Minimal Maintenance, no occaisional discharge is required; no memory.
c. Substantial energy density, ability for yet increased capacities.
a. Subject to aging, even if not in use, storing the battery from a cool situation from 40 percent state-of-charge minimises the aging impact.
b. Subject to transportation laws, shipment of greater quantities of Li-ion batteries may also be subject to regulatory management. This restriction does not cover personal carry-on electrical batteries.
c. Calls for protection circuit, protection circuit restricts voltage and current. Battery is safe not really provoked.
d. Not fully mature, adjustments in metal and chemical combinations impact battery verification results, especially with some short assessment methods.
e. Expensive to manufacture, about 40 percent higher in cost than Ni-Cd. Better manufacturing approaches and substitution of scarce metals with lessened cost selections will doubtless lower the cost.
f. Moderate discharge informed.
The interest on Intrinsically safe batteries is clear, and various manufacturers are stepping up their companies offerings fulfill the demands of high-risk applications. Offshore oil rigs, nuclear plants and areas that handle flammable fumes all have requirements for intrinsically safe ATEX batteries.
