Buyers' Guide: 10 things to know about EVs
Search Driven for vehicles for sale
Headlines such as “Tomorrow’s vehicles — today” or “The clean, green future of the car” feature in most media stories about EVs and there is no doubt that the technology has some exciting potential, especially in countries like New Zealand that generate most of their electricity from renewable sources.
But people also have questions. When you consider that cars powered by petrol have been in New Zealand since 1898 and multiple generations have spent their lives using them to get around, it’s only natural for people to be unsure about changing to something different.
That’s part of the reason why , for the last few weeks, a group of electric vehicle (or EV) owners have been travelling from one end of the country to the other to promote the technology.
AA spokesperson Dylan Thomsen joined passionate EV owner Sigurd Magnusson in a Kia Soul on the leg from Wellington to Palmerston North.
Here are 10 things that ordinary motorists might want to know about the day-to-day realities of owning an EV.
1 An EV is just a car running on different fuel
Regardless of whether a car runs on petrol or diesel, we still see it as a car. However, for some reason, people expect a vehicle that runs on electricity to be “different” in some way.
The reality is that they still have four wheels, a steering wheel, accelerator and brake pedals and you use them just the same way, apart from a couple of minor differences.
It’s a bit strange to not hear any engine noise when you start them and instead of a fuel gauge you have a battery gauge similar to the one on your cellphone.
Aside from that, the only things drivers are likely to notice are that they are extremely quiet to ride in and they also have better acceleration than most fuel-powered cars.
The fact that even basic EVs are extremely quick off the mark is something that many drivers on the rally enjoy, even if they often say it like it’s a bit of a naughty secret.
2 Their range might be more than you think
Unless you are willing to shell out big bucks for a Tesla, most EVs have a range of between 100-200km on a full battery. The type of driving you do will affect your range, and travelling at 100km/h on the open road will use your power quicker than in an urban environment.
The Kia Soul I was in used half its battery going from Peka Peka to Palmerston North — a trip just over 80km. We then plugged into a ChargeNet fast charger in the centre of Palmerston North and 14 minutes later the battery was back to 80 per cent capacity.
Another driver had gone the 140km from Wellington to Palmerston North in a Leaf and reached their destination with 15 per cent left in their battery.
With fast chargers popping up in more locations, it is possible to use an EV for a moderate length trip like that, charge for 30 minutes and the battery will be fully topped and ready to go again.
3 A bit more planning of your trips is needed
While driving an EV, I was much more aware of the percentage of energy left in the battery than I would normally be about fuel in the tank. And the owners I spoke to, did say you need to plan your travel a bit more.
Margaret Baker is a Leaf owner from Whangarei and isn’t able to make a trip to Auckland in one go, so she will factor in a short stop at a charging point along the way where she might need to be there for 15-30 minutes.
Most of the EV owners find overnight charging gives them more than enough juice to do their daily driving and they only occasionally need to use a charging station while out and about.

4 Saving $ on running costs
The cost savings on fuel from an EV can be huge. Magnusson has had a Nissan Leaf for two years and, by using a timer in the vehicle to charge it after 11pm when rates are cheaper, he gets about 5000km of driving for $100 of electricity.
To travel that distance in my Mazda 6 I’d be looking at about $700 for petrol. “The cost of a cup of coffee will largely get me through my week’s worth of motoring,” says Magnusson.
The Government has made EVs exempt from paying Road User Charges to encourage their uptake — and that helps keep their running costs down — but at some stage that will change.
The other side of the equation is that the purchase price for an EV is high for a lot of people. You can find a used Leaf for upwards of $12,000 while new options range from about $60,000+.
As depreciation on the initial outlay contributes significantly to running cost calculations, they’re considered as more expensive than a petrol-fuelled car.
However, as the number of EVs being produced worldwide increases, these prices will likely come down.
5 How long do they take to charge?
This varies between vehicles and what type of charger you are using.
For Magnusson’s Nissan Leaf it would take about 10 hours to fully charge if he was using a standard wall plug compared to five hours from the specialised unit he had installed on the outside of his home.
If you are using a fast-charging station (and more are appearing around the country), it can take 10-30 minutes to recharge.
6 Do they need special maintenance?
EVs are cars and so you still need to get your regular WoF inspection and replace things such as tyres, wiper blades, brakes, etc.
In terms of what’s under the hood there are a lot less parts than in an internal combustion engine; so there is less to wear out or break.
You don’t need to go to some sort of special EV mechanic (although Tesla is a slightly different story) and Magnusson takes his Leaf to the same garage he has used for his other vehicles.
7 What happens when the battery needs replacing?
This is a question that a lot of non-EV owners have. It’s a a tough one to answer as none of the owners I talked to had needed to replace a battery — or known anyone in New Zealand who has.
The reality is that the batteries in the vehicles do degenerate over time and this will reduce the amount of charge they can hold.
It’s hard to put a timeframe on how long this will take to happen as the amount of driving, the type of driving and even the climate can affect how well batteries last.
If you keep an EV long enough, a point will come when the battery needs replacing and Magnusson says replacement batteries overseas can cost from $5000-$10,000.
The good news is that battery technology is improving so putting in a new battery in the future would mean you could travel further than in the original model.
8 You don’t have to have a garage
A lot of the owners I spoke to do not have a garage at home but that hasn’t stopped them being able to charge overnight.
Some have had an electrician set up a charging box on the outside of their house (costing about $1000) while others just use an indoor socket, and use the vehicle’s charging cord to connect through a window.
9If you can plug in your cellphone to charge, you can charge an EV
There is nothing complex about pulling into a service station and filling up a car with fuel.
It’s just as straightforward to fill up an EV. You simply pop open the cover like you would for fuel and plug in a charging cord.
It’s just like a supersized version of charging your phone or laptop — nothing fiddly or complex.
10 What is it that makes owners love their EVs so much?
If you spend any time with an EV owner, you will quickly find out how passionate they are about their vehicles.
For some it is due to the environmental benefits of zero emissions, while for others it is more about getting an equivalent of 30c per litre fuel cost savings or reducing reliance on oil from overseas.
One owner summed it up by saying that every time she heard the “click” of the plug when she charged her car, it made her feel good.
