Update: This Publicly Available Specification (PAS) is being updated to include information on the specification of ‘smart’ EV chargers. ‘Smart’ EV chargers have the capacity to respond to peak electricity demand, which helps to manage load on the electricity grid, and can reduce your charging costs. 

The updated specification is in draft form and is currently open for public comment until 19 May 2023.

The current Publicly Available Specification (PAS) for electric vehicle (EV) chargers for residential use is intended to respond to increasing uptake of EVs in New Zealand and a need to provide consumers with quality guidance on safe, efficient and smart home chargers.

EVs are typically sold with a portable charger intended for back-up use when needed, sort of like an emergency spare wheel. The safest and best way to charge your EV at home is using a wall-mounted charging unit that is connected into the electrical wiring of your home. Please refer to manufacturer instructions (for appropriate charging levels) and WorkSafe guidelines (for safety). 

This PAS describes the types of EV chargers suitable for use in residential homes. It provides an overview of things you need to know and questions to ask sellers of vehicles and chargers. It also includes a technical specification for energy efficient, safe, interoperable residential chargers that will perform well for many years.

By building on existing progress in building a national EV charging network, we will help ensure the national residential charging station network is energy efficient and future-proofed.

The PAS is free to download via Standards New Zealand.
