Charging an EV
Filling your car with low emissions, Kiwi-made electricity is easy to do at home or while out and about.
It's cheap and clean at home
The most economical way to run your EV is to charge at home off-peak. That’s when the demand for electricity is at its lowest across New Zealand – so it’s cheaper and highly likely to be generated by sustainable sources like hydro, geothermal and wind.
Charging at home off-peak is like buying petrol at around 40c/litre, depending on your electricity retailer. Prices vary at peak times and at public chargers when you're out and about.
Home charging devices
A dedicated wall-mounted charging unit at home or work makes charging your EV simple, safe and efficient. Many have ‘smart’ features, which give you greater control over charging, and could allow your electricity supplier to signal low cost and low demand times to charge.
Portable 3-pin cable
A portable back up charger is typically supplied with your EV when you buy it. These can be used when other charging options aren’t available, but are slower charging than wall-mounted units and commercial chargers like those found at shopping malls and parking buildings.
Charge an EV by just plugging it in
It's really as easy as charging a phone.
- Charge inside or outside. It’s all good, rain or shine, so long as all equipment is designed for use in New Zealand and for the conditions in which it will be used.
- Smart home chargers make off-peak charging easy. Smart wall-mounted units can receive a signal from your electricity supplier to charge when the cost to you is lowest.
- Choose the right power company. Check off-peak times and tariffs, and if they offer special rates for EV owners.
Tips to get more out of a single charge
- Fully charge your EV before you set off.
- Warm up the interior before you unplug the EV.
- Inflate tyres to the right pressure.
- Drive smoothly at a steady speed.
- Be aware that cold weather reduces an EV's range, particularly if heaters and demisters are used.
- Remove any heavy luggage or accessories or you don't need, such as roof racks.
How to charge an EV safely
It’s important to use the right equipment – in the right way – to protect your wiring and keep everyone safe.
- Never use extension cables.
- Never take a cable across a footpath to charge.
- Do not use devices to connect the charging cable to the power supply (such as multi-boxes, double plugs or travel plugs).
- You can use an adaptor to connect the charging cable to the car, provided it is confirmed for use by the manufacturers of the vehicle and the cable.
- Never use modified charging equipment such as overseas equipment that has been fitted with a New Zealand plug. Never use damaged or faulty charging equipment. Have it checked by the manufacturer.
Equipment safety checks
When buying an EV, including a used import, you should only be supplied with charging equipment (such as cables) designed for use in New Zealand.
Do not use equipment that doesn’t display a voltage range that includes 230 V, doesn’t have a New Zealand plug, or has been modified (even to fit a New Zealand plug). It isn’t suitable for New Zealand’s electricity supply. Even if it appears to work, you can’t be sure the in-cable safety device will work when it needs to.
Some cables come with an industrial or caravan plug that allows faster charging. These require an electrician to install a special wall power point.
When buying a charging cable or wall-mounted charging unit, or purchasing an EV with a charging cable included, ask the seller for a signed copy of a Supplier Declaration of Conformity. This declaration shows the unit has been tested and meets electrical safety standards.
Wall-mounted charging units must be installed by a registered electrician who should:
- install a separate sub-circuit.
- make sure the cable to the socket is capable of supplying the power that the unit can deliver. A circuit capable of supplying 32 Amps will futureproof the installation.
- install a Type B RCD.
- be able to confirm the charging equipment has a Supplier Declaration of Conformity to show the unit has been tested and meets electrical safety law.
How to charge on the road
Use them to drive beyond your EV’s battery capacity in one go. They can add around 100km of range to the battery in 20-30 minutes. They typically cost about $10 per 100km. Many plug-in hybrid EV can’t use them.
Top up while you do something else. Charging is usually free and can take several hours. Find them at places like shops, hotels and tourist attractions. Bring your own supply lead.
Tips for using a fast charger
Companies installing fast charging stations include local electricity networks, ChargeNet and Chargemaster.
- No cable required. All fast charging stations have tethered CHAdeMO and/or CCS Type 2 cables.
- Create an account online first. Once signed up, you can access the fast charging network and enjoy easy billing and payment.
- Fast charge occasionally rather than frequently. It seems to be better for your battery.
- In a hurry? Charge to 80%. The last 20% of the battery takes longer to charge, so use the option to charge only to 80%.
Find a public charger
Websites and apps show the locations of public chargers, whether they’re fast or slow, if they’re in working order and what type of connectors or sockets are provided or required.
