This Recommended Practice describes installation practices for Energy Storage Systems (ESS) such as battery systems, flywheels, ultra-capacitors, and smart chargers used for electric vehicle (EV) vehicleto- grid (V2G) applications.<\/p>\n
Products and Applications Included<\/b><\/p>\n
Products and applications that are covered by this Recommended Practice include:<\/p>\n
While Compressed Air Energy Storage (CAES), Pumped Hydro Storage (PHS), and Thermal Energy Storage (TES) are not covered by this Recommended Practice (see Section 1.2), electrical equipment and components for use in CAES, PHS, and TES should be installed in accordance with this Recommended Practice.<\/p>\n
Products and Applications Excluded<\/b><\/p>\n
Products and applications that are not covered by this Recommended Practice, but that are discussed in informational Annexes, include:<\/p>\n
Electrical energy can be used to create hydrogen that can be stored for later use. Hydrogen is considered to be fuel rather than means of energy storage. As such, hydrogen is not covered by this Recommended Practice. Additionally, Superconducting Magnetic Energy Storage (SMES) is not covered by this Recommended Practice due to the extremely short discharge time and limited energy capacity that restricts its application to power quality applications only, and not to longer-duration energy storage applications.<\/p>\n
Regulatory and Other Requirements<\/b><\/p>\n
\nAll information in this publication is intended to conform to the NEC (ANSI\/NFPA 70). Installers shall follow the NEC, applicable state and local codes, manufacturer\u2019s instructions, and contract documents when installing Energy Storage Systems (ESS).<\/p>\n
\nOnly qualified persons as defined in the NEC familiar with the construction and installation of Energy Storage Systems (ESS) and ESS devices and system components shall perform the technical work described in this publication.<\/p>\n
\nAdministrative functions such as receiving, handling and storing, and other tasks may be performed under the supervision of a qualified person. All work shall be performed in accordance with NFPA 70E, Standard for Electrical Safety in the Workplace.<\/p>\n
\nGeneral requirements for installing electrical products and systems are described in NECA 1, Standard for Good Workmanship in Electrical Construction (ANSI). Other NEIS provide additional guidance for installing particular types of electrical products and systems. A complete list of NEIS is provided in Annex F.<\/p>\n
Mandatory Requirements, Permissive Requirements, Quality and Performance Recommendations, Explanatory Material, and Informative Annexes<\/b><\/p>\n
Mandatory requirements in manufacturer\u2019s instructions, or of Codes or other mandatory Standards that may or not be adopted into law, are those that identify actions that are specifically required or prohibited and are characterized by the use of the terms \u201cmust\u201d or \u201cmust not,\u201d \u201cshall\u201d or \u201cshall not,\u201d or \u201care required,\u201d or \u201cmay not,\u201d or \u201care not permitted,\u201d or by the use of positive phrasing of mandatory requirements.<\/p>\n
\nExamples of mandatory requirements may equally take the form of, \u201cequipment must be protected . . .,\u201d \u201cequipment shall be protected . . .,\u201d or \u201cprotect equipment . . .,\u201d with the latter interpreted (understood) as \u201c(it is necessary to) protect equipment . . .\u201d<\/p>\n
\nPermissive requirements of manufacturer\u2019s instructions, or of Codes or other mandatory Standards that may or not be adopted into law, are those that identify actions that are allowed but not required, are normally used to describe options or alternative means and methods, and are characterized in this Recommended Practice by the use of the terms \u201cmay,\u201d or \u201care permitted,\u201d or \u201care not required.\u201d<\/p>\n
\nQuality and performance recommendations identify actions that are recommended or not recommended to improve the overall quality or performance of the installation and are characterized by the use of the terms \u201cshould\u201d or \u201cshould not.\u201d<\/p>\n
\nExplanatory material, such as references to other Codes, Standards, or documents, references to related sections of this Recommended Practice, information related to another Code, Standard, or document, and supplemental application and design information and data, is included throughout this Recommended Practice to expand the understanding of mandatory requirements, permissive requirements, and quality and performance recommendations. Such explanatory material is included for information only, and is identified by the use of the term \u201cNOTE,\u201d or by the use of italicized text.<\/p>\n
\nNon-mandatory information and other reference standards or documents relative to the application and use of materials, equipment, and systems covered by this Recommended Practice are provided in informative annexes.<\/p>\n
\nInformative annexes are not part of the enforceable requirements of this Recommended Practice, but are included for information purposes only.<\/p>\n","protected":false},"excerpt":{"rendered":"
