Installing a charging station

When sourcing and installing a public charging station there specific considerations to take into account.

Sourcing a charging station

All public charging stations should be either Mode 3 or 4 and must comply with the relevant safety standard. They should also have the recommended connectors.

Before purchasing a charging station (and other electric vehicle supply equipment (EVSE)) you should assure yourself that the product is suitable for use in New Zealand.

It is recommended that you request that the supplier provides you with a supplier declaration of conformity (SDoC) and a test certificate stating that the EVSEhas been tested to the relevant standard.

In particular, you should check that:

• the model number on the SDoC and test certificate matches the model number of the product you intend to purchase
• the product is labelled as suitable for a voltage of 230/400 and a frequency of 50 hertz

Suitable charging station modes

A ‘mode’ describes the safety communication protocol between electric vehicles and charging stations. These are internationally recognised definitions. Only Mode 3 and Mode 4 are suitable for public charging infrastructure in New Zealand. The modes are outlined below:

Away from home infrastructure

Charging mode	Description	Recommended use
Mode 2 - commercial	The electric vehicle is connected to the AC supply network (mains) using a standardised single-phase or three-phase socket outlet. Single-phase and three-phase socket outlets must not exceed 32A or 250 V AC. An in-cable control and protection device (IC-CPD) must be used to protect the user. Charging capability up to 22kW.	Suitable for controlled environments with restricted access. Eg hotels, fleet car parks and repair facilities.
Mode 3	The electric vehicle is connected to the AC supply network (mains) using an electric vehicle charging station. The control device is contained within the electric vehicle charging station, permanently connected to the AC supply network (mains). Charging capability up to 43kW.	Suitable for public charging infrastructure.
Mode 4	The electric vehicle is connected to the AC supply network (mains) using an electric vehicle charging station with an off-board charger. This mode supplies the electric vehicle with a DC supply. The control device is contained within the EV charging station, permanently connected to the AC supply network (mains). Charging capability up to 50kW.	Suitable for public charging infrastructure.

*Refer to the ‘Charging an electric vehicle’ section for further information about electric vehicles and infrastructure that can affect the rate charge.

*Mode 1 and Mode 2 are for home charging and not covered in this guidance as they are not appropriate for public use. Find out more here(external link).

Performing the electrical installation

No person may install an electric vehicle charging station unless they are licensed and competent to do so.

Depending on the existing infrastructure, the installation may also require electrical works by a certified electrician or electrical engineer. A competent electrician or electrical engineer will be able to advise you on what is required.
