Secondary Batteries...

Standard covers recommended information for an objective evaluation of emerging energy storage technology by a potential user of any stationary application. Storage technologies are those that provide a means for the reversible storage of electrical energy (i.e., device receives electrical energy and can discharge electrical energy later). The storage medium may be electrochemical (e.g., batteries), kinetic (e.g., flywheels), electrostatic (e.g., electric double-layer capacitors [EDLCs]), thermal or other medium.

1.1 This Standard applies to emergency lighting and power equipment for use in unclassified locations and intended for connection to branch circuits 600 V or less. Intended to supply illumination, power or both automatically to critical areas and equipment in the event of failure of normal supply in accordance with NEC Article 700 or 701, NFPA 70, Life Safety Code, NFPA 101, Fire Code, NFPA 1, International Building Code (IBC) and International Fire Code (IFC).

NFPA 400 consolidates fundamental safeguards for the storage, use, and handling of hazardous materials in all occupancies and facilities. The Code does not apply to storage or use of hazardous materials for individual use on the premises of one- and two-family dwellings.

A resource for facts on safe response to electric and hybrid vehicle incidents involving damaged high voltage batteries, battery fires, extrication challenges, submersion, and charging stations. This document covers the vital aspects of EV/hybrid hazard awareness and procedures, including information from related NFPA codes and new consistent Moditech Rescue Solutions® vehicle diagrams.

1.1 These requirements cover electrical energy storage assemblies such as battery packs and combination electrochemical capacitor assemblies and modules that make up these assemblies for use in electric-powered vehicles as defined in this standard.

IEC 61427-2:2015 relates to secondary batteries used in on-grid Electrical Energy Storage (EES) applications and provides the associated methods of test for the verification of their endurance, properties and electrical performance in such applications. The test methods are essentially battery chemistry neutral, i.e. applicable to all secondary battery types.

This Standard provides a method of presenting technical information relating to the selection of storage batteries for photovoltaic systems and to the precision of that information.
Note: A distinguishing feature of photovoltaic (PV) power systems is the unpredictability and limitation on the amount of charging power available and hence on the charge-d ischarge cycles imposed on the storage battery.
1.2
This Standard includes procedures designed to verify the capacity, efficiency, and longevity of storage batteries.

Replace this clause of the RD with the following: 1.1.1 Equipment covered by this standard This Standard applies to UPS, whose primary function for this Standard is to ensure continuity of an alternating power source. The UPS may also serve to improve the quality of the power source by keeping it within specified characteristics. This Standard is applicable to movable, stationary, fixed, and built-in UPS for distribution systems up to 600 V AC.

(a) General requirements—(1) Batteries of the unsealed type shall be located in enclosures with outside vents or in well ventilated rooms and shall be arranged so as to prevent the escape of fumes, gases, or electrolyte spray into other areas.

(2) Ventilation shall be provided to ensure diffusion of the gases from the battery and to prevent the accumulation of an explosive mixture.
