You do not need to install a specialised home charger (mode 3 or 4) for your EV provided you have a charging supply cable (EVSE - mode 2) with a 3-pin plug at one end. This can be used to charge your car from any 10amp electrical socket in the country. Please note that these have a protection device situated no further than 300mm from the 3-pin plug. It is important to protect the "live" end from the electric socket to the protection device, and for this reason it is not recommended that you use an extension cord.
* The actual charger is inside your vehicle and every model of EV will have its own maximum speed at which the charger can accept power. What this means in practice is that the average low-range car can fully charge overnight on a std NZ 3-pin power socket.
If you have purchased a long-range vehicle you may not find a mode-2 charging method adequate, unless you are prepared to do small top-ups rather than cycling through the full battery (not recommended.) In this case, you may need to install a dedicated wall charger*. Indeed some premium models come with a dedicated wall charging point as an optional extra.
Even with a powerful wall charger, your EV will still only charge at the maximum rate that its onboard charger can handle. ie: if your car can accept a maximum of 18A, it's pointless installing a 32Amp charging point unless you are future-proofing. Whatever size of battery you have, an ideal starting point is to choose a dedicated home charging point that will charge your entire battery overnight. This also means that you can get a decent top-up in just a couple of hours.
Most of these wall chargers will work on single phase just fine, although some are manufactured for 3-phase power.
Visit our list of EVSE dealers. Many EV dealerships can also supply charging equipment. Check with your dealer for recommendations or ask in your local EV Owners Facebook group.
In New Zealand, it is not permitted to use or allow the use of a Mode 2 supply for public charging for an electric vehicle, which in practice means a business needs to install a wall or column AC Charge Point. If you are intending to provide a public charging station or a staff charging station, we recommend you talk to reputable, specialist charging device dealers, such as Schneider, Jacksons, Delta, and echarge. We also recommend you read the Worksafe Guidelines.
DC Charging stations are unnecessary and cost prohibitive for most work carparks. If you do wish to install a DC charger, we recommend you contact ABB, or the NZ Veefil agents: ChargeNet NZ Ltd. ChargeNet have a user billing system whereby the cost of the electricity supplied and maintenance can be recovered.
