Evready is at the forefront of EV charger installs in New Zealand. Our goal is to provide you with an efficient system that is easy to use and makes having an EV car a breeze to own and operate. Our companies full in house systems make the process from quote to delivery easy and stress free, no unknown contractors and no middle man, we are a one stop shop for EV chargers.
The answer depends on a few factors that we can talk through with you. We will be able to determine the right charger for your car, how fast you want it to charge your car and what supply you currently have available.
Everything is possible, If your switchboard is far away from your proposed charger location or want to put it on your drive or external garage, then the cost to install ducting and wiring may be higher. Ask us about cost-saving alternatives.
Yes you will need to have the work signed off as being compliant to current regulations and standard, all our team are full NZ registered electricians who will be able to carry out the work compliantly and provide full documentation and sign off.
No problem, we specialise in making these types of installs possible. Get in touch and we can explain the process and talk with you on a solution that can work.
Anywhere that we can get a cable to! All our chargers have an IP rating so can be installed almost anywhere you desire, get in touch for a quote for any location specifics or questions you may have.
The battery capacity of your electric vehicle (EV) will determine how much energy can be stored and, therefore, how long it will take to charge. The battery capacity differs for each car.
The Nissan LEAF, for example, has a battery capacity of 30 kW, while the Tesla Model S has a capacity of 100 kW. To figure out how long it takes to charge your battery, divide the battery capacity by the charging power.
Now that you have some overview as to why electric vehicle manufacturers and countries are starting to adopt the Type 2 plug as standard, it is worth considering that it makes more sense to charge with the newer Type 2 charging plug, even if your electric vehicle is Type one. Seeing that the New Zealand standard is Type 2 this will be the plug you will most commonly come across at public chargers across the country. Purchasing a Type 2 charging solution now could save you money down the track as they are relatively the same price as Type 1 solutions. All Type 1 electric vehicles can be charged from any Type 2 charger. The only thing you need is a Type 2 to Type 1 conversion charging cable. All our chargers we supply can come with a Type one or Type 2 plug top and if you do decide the Type 1 is what you need and want to change later on to a Type 2 we can convert the cable without having to change the whole charging unit in a simple and straightforward process. Get in touch to find out what plug is best for you!
An external charging cable is only necessary if the charging station does not have a permanently connected charging cable. There are some public chargers in New Zealand that require you to have your own charging cable to plug into much like you plug into a wall socket. These could become more popular in time as there is the issue around cable theft and damage to public chargers. However currently most chargers have a permanently connected cable for use.
Energy quantities when talking about chargers are always given in kilo-watt-hours (kWh) the same as your standard power bill. This tells you how much energy was charged or used for one hour. A 7 kW charging station therefore has a power requirement of 7 kW per hour. In other terms this means the power of 70 x 100watt light bulbs burning for 1 hour. This may seem like a lot of power but in reality it is a lot cheaper than you think! We can give you an estimated cost on what we project your charging could cost you per year and also ways to reduce your charging cost with charge scheduling and monitoring.
Electric Vehicles in New Zealand are rated to consume somewhere between 15 and 25 kWh per 100 km however this is not always the case and should be taken with a grain of salt as with any stats given by vehicle manufacturers. EVready advise you to compare the official consumption values with the experiences of other EV enthusiasts when buying an electric vehicle. Independent reviews and long-term tests can be found on the internet for every electric vehicle which will give you a realistic and verified review on real life vehicle range and efficiency.
Charging power is the amount of energy that can be introduced in the battery per hour.This all varies depending on:
1. Your buildings connection to the grid.
2. The capacity of your Electric Vehicle Charger.
3. The onboard charger in your Electric Vehicle.
The weakest of the above three factors determines the charging power.
Let’s look at each of these factors below:
Your Buildings Connection to the grid:
There’s a maximum deliverable power to all Buildings or sites.
It’s the power that your facility can deliver to all electrical devices connected to it.
For example, if you have 4.4 kW maximum deliverable power at your house, all devices that are connected to that network can never consume more than 4.4 kW combined.
That includes Electric Vehicle Chargers, cooking appliances, lights and general power.
You can increase the size of your buildings connection to the grid by upgrading the switchboard, cabling and fuse sizes at the road.
It’s a relatively straight forward process in most regions in NZ with the Auckland region being the easiest to complete upgrades for multiple EV chargers
The EV charger:
Every charger has a maximum of power that can be transferred from the installation to the vehicle. Wallbox chargers can charge between 7.4 kW and 22 kW. A direct current (DC) charger can charge up to 350 kW.
For most residential and light commercial applications 7.4kW is more than enough to charge your Vehicle overnight without having to upgrade your grid connection, switchboard or incoming mains.
The Electric Car:
The maximum charging power of the vehicle is the final limitation. It’s determined by a device on your car that feeds the electricity to the battery of your car. This device is called the onboard charger.
It’s power can range from 3.7 kW to 22 kW single phase and three phase depending on the model and manufacturer As technology improves, the onboard charger in the newer models of Electric Vehicles also improves with greater onboard charging capacity as well as reduced onboard charging times.
Charging your Electric Vehicle with a charger is faster, cheaper and most importantly, SAFER.
- Faster, because charging with a charger is around eight times quicker than with just a cable plugged into a regular socket.
- Safer, because the charger is smart and will control the flow of energy through the cable, preventing overloading and fire risks.
- Cheaper, because you can charge your car at off-peak times when electricity is cheaper than normal.
Most chargers and public charging stations offer rates up to 22 kW while your domestic socket can only deliver rates up to 3.7 kW, while 2.3 kW is the maximum recommended. How fast you can charge your car at the end depends on the battery capacity of your car and the actual charging power available.
Charging your car with a Wallbox EV charger is over eight times faster than charging it with the ‘emergency wall charger’ that comes with your vehicle!
Manage your EV’s charging
If you charge your car with a Wallbox EV charger you have the possibility to manage your charging via Wallbox’s easy-to-use app on your phone.
It’ll tell you when your car is fully charged, it lets you adjust the power rate at which you want to charge and has an integrated timer so you can decide to start charging at night when electricity is cheaper.
Using smart charging saves you money, it enables because you to charge your car when electricity rates are off-peak and/or low.
Energy retailers try to even out the peaks when electricity consumption is at its highest (when consumers come home from work in the evening / get up for work in the morning). Resulting in electricity being cheaper late at night or in the early hours of the morning. These are typical off-peak hours when consumers electricity not so many people ais at its lowest. With a simple click on your phone, the Wallbox app tells your charger when to start charging your car.
The cost of charging your EV depends on the electricity rates of your country of residence, your electricity provider, at what time of the day you charge, and whether you charge at home or at a public charging station.
Electric car charging at home
The average price of one kilowatt-hour ranges from $0.23 to $0.29 in New Zealand. Therefore the price of fully charging a car differs depending on your energy retailer, if you have a renewable energy source on your property like solar panels, hydro-electric or wind turbines your Energy is next to free!
Let’s say you drive a Nissan LEAF with a battery capacity of 40 kilowatt-hours in allows you to Drive your electric vehicle from Auckland City to Taranaki, 280 km with one charge. You’ll have to estimate 40 x $0.23 = $9.20 for one full charge. This means that the power consumption cost per kilometer is $9.20/ 280 = $0.032 for a Nissan LEAF in Auckland.
If you have a charger installed at home, with some energy retailers, you can benefit from lower electricity costs by charging at off-peak hours.
Via the Wallbox app on your smartphone, you can communicate with your Wallbox and pre-set the start and stop times for your vehicle charger.
You should also consider that slower wallbox charging is a lot cheaper than fast charging, charging your electric car overnight at your house where it’s parked for longer hours makes more sense.
DC fast charging is primarily designed for larger commercial applications, the cost and size of the supply needed is substantially more than AC chargers which is part of the reason it is less common. If you have a requirement for DC fast charging get in touch and we will provide some options to suit your need.
The charging lead that comes with cars should be thought of as your spare tire and should really only be used in a handful of situations, the chargers have been known to overheat and cause issues with the electrical system, we generally discourage the use of these for day to day charging and highly recommend looking into the use of a wallbox unit specifically designed for home and business day to day use.
Yes any building or home with an electrical supply should be able to handle our chargers, with integrated load limiting technology we can program your charger to never exceed the maximum current limitations of any home or business.
No with our chargers you will not be able to overcharge the car, once the charge cycle is finished the car “talks” to charger and the unit turns off automatically, it will restart again when it detects a power drop in the car to keep it topped up and ready to go. Most vehicle manufacturers recommend having your car plugged in as often as you are parked.
