However, you still have to factor in the cost of having a fast charger installed at home. How much does that typically cost? I would need to hope that my body corporate would let me install one in my car park.

 

 

My understanding is this is less of an issue in NZ due to our adoption of 240V vs the American 120V standards, but extension cords don't play well with EVSE chargers so you'd need to plug directly into the wall?

 

 

 

I'm curious about this myself as I don't have a garage to charge an EV in, so I'd need to get something installed in our carport, but I have to figure out whether to get a dedicated charger or just a caravan plug installed; and whether it needs to be wired into a separate RCD to the rest of the house. 

 

 

 

 

I am looking at around 2k for a 7kw charger to be installed in my garage (it can also go outside if I wanted...they're waterproof I believe).

 

I could just charge my Kona via a standard plug but this would take 43 hours from 0-100% because it has such a big battery. With the 7kw charger, it will take 9 hours to fully charge (so overnight is easy...and, let's face it, I don't expect to be charging from totally empty ever!).

 

It is an extra expense to consider when buying an EV, but I look at it as future-proofing my home and even a selling point IF I was to sell my home.

 

This is the charger I am going to have installed in my garage...

Thanks, that is a bit cheaper than I thought.

 

Unfortunately I have a feeling that installing one of these in a communal car park might be a lot more complicated than a freehold garage. I guess my car park would need to be wired up to a dedicated phase so that I can be billed for the power usage. Does anyone have any experience with this?

Or, maybe you can convince the Body Corp to install a charger in a dedicated carpark for all to use...a charger that you pay as you use (time and power usage SO no-one hogs the park! hehe).

 

Contact Transnet and ask them if they have dealt with this situation and what solutions they may have. I've found the guy I'm dealing with at Transet very helpful.

I paid $800 to get a 32A dedicated cable to my main switchboard. Limited it to 16A and got caravan socket installed.

I figure on maybe 800 more for a 32A box. But as I can still charge fine using 16A supply, I can't justify the extra cost.

Rather than look at how big the battery is to recharge from empty look at how many km you drive each day and how long it would take to replace that.

I reckon your thinking is really good, afe66.

 

I have probably gone overboard ordering a more expensive/faster charger in my garage as the vast majority of my daily driving comes in under 50km. 

 

On the other hand, I'd like to be able to do 400+ km (as the Kona can) without worrying that I have not left enough time to charge overnight.

 

I want my Kona to be as near as possible, in terms of practicality, as my current fossil-burning car. The Kona has been the tipping point for me going EV (especially as this will be my only vehicle).

 

The Tesla Model 3 was also a possibility, though I cancelled my order given the Kona's equivalent range and earlier availiability (as well as the Kona's more practical design - compact SUV as opposed to compact sedan).

 

One final point....having driven past some beautiful hydro lakes in Central Otago recently, it was really nice to look at them and think that they will soon be running my car instead of dirty oil imported from overseas. 

 

I will be supporting NZ energy companies as well as polluting our world less. I am very very happy (and lucky to be able) to pay a premum to do that :-)

I have seen a presentation from these people https://www.abelectrical.co.nz that looked at the approaches of providing EV charging points by a body corporation in an apartment building garage. It is not straight forward if you want to do it well so as to allow for expansion as more EVs arrive.

 

I looked at it for a Tesla in my apartment garage and had a quote done - $6,000 for a 32 amp single phase setup that included metering to allow for separate billing.

 

In the end I bought a Hyundai Ioniq and as I have a normal plug next to my park in the garage I use this for overnight charging which works for the Ioniq with its battery size. To meter the amount of electricity I use I have a one of these units https://www.apple.com/nz/shop/product/HKEH2X/A/eve-energy and this sends usage to an app on my phone and then I will be paying the BC once a year for the electricity I have used. Because most of my driving is out of town on long trips I charge mostly using Chargenet out of town but my total consumption of power at the apartment garage is just over 700 kWh in the 9 months I have had it so far.

 

 

 

So for me this has worked well but has required the cooperation of the BC. The BC is looking to what they might do as the number of Tvs increase - currently I am the only  one. 

 

It was the Body Corp Chairs Group of NZ that had an information evening in Auckland where the issues of how to manage EVs in an apartment garage was discussed and the presentation from AB Electrical was the one that I thought showed the most promise if a BC was to set up a garage with multiple level 2 (32 amp) charging points.

Can you get a 7KW portable EVSE for the Kona? Then you would just need to get a 32A power socket installed. Probably a PDL 56 series socket.

My understanding is that yes you could do this - there are cables for this available. You still have the cost of the 32A line from the main switch board and the metering. If the main switch board is several floors from where you have a car park then it costs. Also the car park may have 100 cars and how many of these 32A lines is a BC going to allow to be installed before there is an issue with capacity? 

 

Also a plain PDL type socket does not come with the advantages of the dedicated wall pods that usually have things like remote monitoring from your cell phone or timing provisions to allow charging at off peal rates etc.

This could actually be quite workable for me because my car usually sits unused for several days prior to going on a long trip, so even with a battery the size of the Kona's I could probably get by with a standard 10A outlet at least as an interim solution.

 

 

So for me this has worked well but has required the cooperation of the BC. The BC is looking to what they might do as the number of Tvs increase - currently I am the only  one.

Thanks, this is really useful information. My place is actually still being built including the parking facility so I might have a word with the developer to see if they've considered this sort of thing.

A 10 amp socket isn't usually a problem to get by with unless you are fully recharging the battery every night.

 

The key is when possible, do not wait until the battery is totally depleted before plugging it in (a small mind set change that ICE drivers can take a moment to get their heads around).

 

An EV will give you approx 6.5 to 7 Km of driving per KWhr of electricty, and a 10 amp socket will give 2.4 Kw per hour or add 15.6 to 16.8 km for range per hour of charging.  So 8 hours of overnight charging on a 10 amp outlet will add 134 km of range or 201 km of range for 12 hours of charging. As long as this is equal or less than your daily commute, you can top the car up to 100% overnight. 

 

So a 10 amp socket is fine if you are not impatient.

On the EV Wiki the NRGKick is recommended - plug in anywhere you can get power - 1/3 phase, whatever current and it will charge. You can get a model with whatever smarts in it that a wallpod would have.

A little bit dependant on the car though, a Zoe will complain and charge quite inefficiently at 10 amps. The type of charger fitted needs a bit more to work correctly.

I bought this   https://bluecars.nz/shop/ray-type2/ charging cable as it allows you to change to amps you are using - I use 8 amps mostly but when visiting family and charging I tend to drop it down to be sure I dont put any particular stress on their wiring. Then it provides the ability to easily use the 16 amp plug at a caravan park although as the number of fast chargers has quickly increased this need is fading. It was needed last Christmas travelling from Wellington to Christchurch as the Kaikoura charger hadn't been upgraded to the new standards and I had to stop at the camp ground for a long lunch break. I guess I would still need this if travelling down the West Coast. Also if a fast charger was out of order and not working it gives the possibility of a 16amp charge rather the 8 - 10 amp charge of a standard plug - just find the nearest camp ground or look on Plugshare.

 

It is a very well made compact unit and although expensive I have been pleased with it - more compact and versatile that the unit that came with the car from Hyundai.

 

Before I bought the car I spent a lot of time thinking about charging but I have to say this has not been an issue since buying the car some 10 months ago and the pleasure of driving the car far eclipses any of the concerns I had about charging.

I now have a WallBox Pulsar charger in my garage.

 

It looks great (smal and unassuming on my garage wall) and the install via TransNet andf SmartControls has been really good.

 

Having said that, I am still waiting for my Hyundai Kona so I cannot comment on how good it is to use. Everything I have read and heard suggests it is good...I will update when I get my Kona.

MAPS in the Hyundai Kona (and Ioniq, from what I understand) bought in NZ are a big problem.

 

From NZ EV Owners group, I have read this: "Hyundai doesn’t support their own maps and traffic alerts. I have a physical button that does nothing when I press it."

 

While Apple CarPlay and AndroidAuto is great in Hyundais, having maps and traffic alerts in-built on Hyundai Kona's and Ioniqs are more essential as charging station locations and drive times to them are most easy to get from in-built maps, as opposed to fussing around trying to plug a charging cable in to a phone while driving.

 

From an NZ EV Owner group Kona owner:

 

Mark Jennings "Hyundai offer lifetime (10 year after last Ionic/Kona is produced) free annual update to Kona/Ionic in rest of world.
I won’t drop this. I think Hyundai world wide won’t like the bad PR it will create."

 

He wants the same lifetime update to maps given worldwide by Hyundai to be offered here in NZ too.
