Safety

The document presents general requirements that Telcordia and participating industry representatives view as applicable to large format non-aqueous rechargeable lithium batteries to replace or interoperate with conventional batteries (i.e., Lead-Acid, nickel-based); function seamlessly with DC power plants; and provide reliable backup power to load equipment in a network environment of a typical telecommunications service provider.

The document provides a 3-level system of VRLA String Safety and Performance Criteria based on Telcordia generic requirements documents. The VRLA string criteria levels are defined as follows: ? Level 1, Safety and Minimal Operability – minimum acceptable level of compliance needed to preclude hazards and degradation of the network facility and hazards to personnel, and needed to ensure battery operability at the installation time in controlled environments.

1.1 This standard covers molded-case circuit breakers, circuit-breaker and ground-fault circuit interrupters, fused circuit breakers and accessory high-fault protectors. These circuit breakers are specifically intended to provide service entrance, feeder and branch circuit protection in accordance with the National Installation Codes in Annex B, Ref. 1. This standard covers instantaneous-trip circuit breakers (circuit interrupters) specifically intended as part of a combination motor controller in accordance with the National Installation Codes in Annex B, Ref. 1.

1.1 These requirements cover electrochemical capacitors for use in equipment such as electronic products, uninterruptible power supplies, emergency lighting, engine starting, and power equipment. These energy storage capacitors, also known as electric double-layer capacitors, ultra capacitors, double-layer capacitors or supercapacitors, consist of either individual capacitors or multiple series and/or parallel connected capacitors with or without associated circuitry.1.2 These requirements do not cover electrochemical capacitors for use in hazardous (Classified) locations.

1.1 These requirements cover primary (nonrechargeable) and secondary (rechargeable) lithium batteries for use as power sources in products.

Safety standard for stationary batteries for energy storage applications, non-chemistry specific and includes electrochemical capacitor systems or hybrid electrochemical capacitor and battery systems. Includes requirements for unique technologies such as flow batteries and sodium beta (i.e., sodium sulfur and sodium nickel chloride). Includes construction requirements, tests and production tests. Also includes requirements for cells used in these systems such as lithium-ion, nickel, Lead-Acid and includes sodium beta and flow battery requirements.

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.

1.1 These requirements cover inverters, converters, charge controllers, and interconnection system equipment (ISE) intended for use in stand-alone (not grid-connected) or utility-interactive (grid-connected) power systems. 1.2 For utility-interactive equipment, these requirements are intended to supplement and be used in conjunction with the Standard for Interconnecting Distributed Resources With Electric Power Systems, IEEE 1547, and the Standard for Conformance Test Procedures for Equipment Interconnecting Distributed Resources with Electric Power Systems, IEEE 1547.1.
