Description

AS NZS 5139 – 2019 Edition – Electrical installations — Safety of battery systems for use with power conversion equipment

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.

AS 5139 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.

AS NZS 5139 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.
