AS NZS 5139 pdf download.Electrical installations — Safety of battery systems for use with power conversion equipment
1.1.1  Scope
This Standard sets out general installation and safety requirements for battery energy storage systems (BESSs), where the battery system is installed in a location, such as a dedicated enclosure or room, and is connected with power conversion equipment (PCE) to supply electric power to other parts of an electrical installation. This Standard sets out the requirements from the battery system up to but not including the PCE. This Standard also applies to pre-assembled integrated battery energy storage systems, which also include PCE(s). This Standard outlines the potential hazards that are associated with battery energy storage systems and their associated battery systems and specifies installation methods that minimize risks posed by these hazards. This Standard is applicable for the following battery systems: (a) Nominal voltage between 12 V d.c. and 1500 V d.c. (b) Connected to either single or multiple PCEs. (c) Using secondary or rechargeable cells. (d) With a rated capacity equal to or greater than 1 kWh and no more than 200 kWh, at — (i) C10 rating, for lead acid batteries; or (ii) 0.1C, for lithium technologies; or (iii) manufacturer’s specified energy capacity, for other technologies. Where an installation includes multiple battery energy storage systems, this Standard applies to each individual battery energy storage system if — (A) the total energy storage capacity is equal to or greater than 1 kWh; and (B) each individual BESS is no more than 200 kWh. This Standard does not apply to battery systems in the following electrical installation types: (1) Premises with critical power continuity requirements (e.g. acute care hospitals, substation support and black start). (2) Telecommunication applications. (3) Electric vehicles. (4) Portable equipment. (5) Uninterruptible power systems (UPS) that are in accordance with AS 62040.1.1 and AS 62040.1.2. (6) Transportable structures and vehicles that are in accordance with AS/NZS 3001.NOTE 1  While this Standard applies to systems of up to 200 kWh, the general requirements of this Standard may apply to larger installations. NOTE 2  This Standard applies for common BESS technologies, and is not specifically written to support all types of battery system installation types or for other storage technologies, e.g. super capacitors. This Standard may be able to be applied in full or in part to the different storage technologies, or the risk approach may be used to assess the hazards and determine mitigations.
1.1.2  Application
This Standard shall apply to battery systems that are constructed on site and used in conjunction with a PCE. This Standard shall apply to the installation of pre-assembled battery systems used in conjunction with a PCE. The manufacturing of pre-assembled battery systems does not form part of this Standard where these products have been type tested and shown to conform to applicable product Standards. This Standard shall apply to the installation of the pre-assembled integrated BESS. The manufacturing of pre-assembled integrated BESS does not form part of this Standard where these products have been type tested and shown to conform to applicable product Standards. Installation, commissioning and documentation requirements are specified for particular equipment in this Standard as follows: (a) Pre-assembled integrated battery energy storage systems (BESSs) — in Section 4. (b) Pre-assembled battery system equipment — in Section 5. (c) Battery systems and BESSs not conforming to Best Practice Guide: battery storage equipment — Electrical Safety Requirements — in Section 6. This Standard shall be read in conjunction with AS/NZS 3000. Pre-assembled integrated BESS, pre-assembled battery systems or battery systems that are constructed on site shall be installed in accordance with AS/NZS 3000, except as varied herein, and with the requirements of this Standard. This Standard is applicable for both grid connected inverter energy systems and stand-alone power systems installations. When the installation of a battery system forms part of a system that is connected to the grid, this Standard shall be read in conjunction with the AS/NZS 4777 series. When the installation of a battery system forms part of a stand-alone power system, this Standard shall be read in conjunction with the AS/NZS 4509 series. Local government, Australian National Construction Code (NCC) and New Zealand Building Code requirements for buildings may also apply where a BESS is installed.
