Abstract

This document specifies the safety requirements of electrical energy storage (EES) equipment designed to be used within domestic, residential or small-scale industrial and/or commercial applications. This document can be applied to both alternating current (a.c.) and direct current (d.c.) EES equipment. This document addresses hazards, to the extent currently identified and as referenced for the relevant technology. These hazards include — (a) electrical hazards; (b) chemical and vapour hazards; (c) mechanical hazards; and (d) fire hazards. This document is applicable to the following types of EES equipment: (i) Pre-assembled integrated battery energy storage system (BESS) equipment. (ii) Pre-assembled battery system (BS) equipment. (iii) Modular assembly battery equipment. NOTE 1 In this document, where the term EES equipment is used, it can be interchanged with battery energy storage system equipment, battery system equipment or modular assembly battery equipment. NOTE 2 A battery module that is a component part of BS equipment or BESS equipment may be separately assessed against this document for pre-qualification as a component part within BS or BESS equipment, or within a modular assembly battery. Electrical energy storage equipment covered by this document includes — (A) EES equipment where the battery contains lithium or lead acid technology as part of the energy storage medium; (B) EES equipment with a rated input/output power equal to or less than 100 kW; (C) EES equipment with a rated capacity equal to or greater than 1 kWh, and no more than 200 kWh when measured at the C5 rate; (D) battery modules, where the input/output voltage upper limit is equal to or less than 1 500 V d.c. (noting that such parts are not accessible to users and energised parts are not accessed by installers); (E) pre-assembled battery storage equipment, or d.c. rated modular assembly battery equipment, where the input/output voltage upper limit is equal to or less than 1 500 V d.c.; (F) pre-assembled integrated battery energy storage system equipment, or a.c. rated modular assembly battery equipment, where the input/output voltage upper limit is equal to or less than 1 000 V a.c.; and NOTE 3 There is no internal d.c. voltage limit of such equipment, as any internal d.c. voltage is not to be accessible, even when equipment is opened for assembly, installation, maintenance or repair on site). (G) Modular assemblies that meet the specifications in Appendix A. NOTE 4 Such modular assemblies (in the configuration tested to this document) are deemed EES equipment for the purpose of this document. (H) The equipment in the scope of this document is permanently connected to an electrical installation. NOTE 5 This document uses the term “electrical energy storage (EES) equipment” in the place of “battery energy storage equipment (BESS)” as referenced in the BPG, to enable greater flexibility in the types of energy storage equipment that may eventually be included in the scope of this document. This document does not apply to the following: (1) Installation design and installation requirements. (2) Grid integration and demand response management. (3) Operational control and communication of an installation. (4) Electromagnetic compatibility. (5) Cyber security. (6) Recycling. (7) Training requirements. (8) Electric vehicles, aircraft and ships. (9) Portable electrical energy storage equipment. NOTE 6 Appendices may have some informative details related to these areas. While this document does not apply to systems with a rated input/output power> 100 kW or capacity> 200 kWh, in the absence of specific standards, the general requirements and principles of this document may be applied to offer guidance in those situations, although there may be additional hazards in those circumstances that have not been identified in this document. This document currently only applies to EES equipment that uses lithium ion or lead acid battery technology. It is intended that it will be revised in future to include other technologies. This document does not provide information on the installation of EES equipment at a site, or multiple EES equipment units together at a site. Installation of an EES equipment should conform to the manufacturer’s instructions and appropriate installation Standards such as AS/NZS 4509.1, AS/NZS 5139 and AS/NZS 3000, and any suitable industry guide for installations.
