No one has commented on the pricing (the rate of 25c/kWh + 25c/minute) seems high to me. (i'd like to see off peak rate or better still a spot price rate).

 

I get there is a cost to install the infrastructure, at $10-$15 to get you to 90% and to only get 100-150km range doesn't seem like good value to me. (maybe i'm asking too much of current EV cars and the immature charging infrastructure).

 

In general terms a 500km trip (Christchurch-Queenstown) would require at least 3 to 5 stops and somewhere between $30-$75. At the top of that price range a small petrol car would be about the same cost.

 

In my ideal world, if I have to stop for 20mins to charge my car then that would be subsided by the activity I would indulge while waiting. eg X number of coffees. = % discount.

 

I'm sure we will see better innovation on pricing over time. 

 

 

The Veefil DC chargers from Tritium (ChargeNet's gear) cost about NZ$45k each. Installing the power infrastructure to support one can cost that much again....and more. The cost of power is relatively cheap for commecial use under 63kw. It's a tiny fraction of what residential users pay. But you have to pay it every month whether the charger is being used or not.....and you're already about $100k down before you charge the first car.

 

So charging. The most expensive car to charge is a LEAF Gen1. They charge slower (often a max of 22kw, not 47kw)....which racks up the per-minute charges. The cheapest LEAF is a 30kWh model as they charge abuot 25% faster than a Gen 2 (and more than 100% faster than a Gen 1) on a 50kw DC fast charger. This is partly because they basically do full speed to 85%, then slow down the charge rate more slowly than a Gen2 24kWh LEAF.

If you have a gen 2 LEAF and only charge to 80%..and if the chargers are available, just charge more frequently. That's the cheapest way to go. If I'm stopping for lunch for an hour in Tauranga, they also have 32amp AC chargers there (free of charge). I'll gain 25% from one of those...then move the car over and top it up on the ChargeNet charger. That saves some money, too, and also reduces the amount of battery heating from fast charging. But I only do it if I know I have something else to do. 

So think about it on the revenue side. Assuming 2kWh / 3 minutes (top speed for any EV). Then an hour for a Tesla with big battery will only yield  $23 / hour. (60 mins * 25c + 40kWh). Maximum revenue per day even if utilisation is 100% (almost impossible even if trying hard) would be $552.

But let's assume the average delivery  rate (those gen 1's) is 35kw and utilisation is a very strong 8 hours / day. That is a BUSY charger.

That would be $70 for the power plus  $120 for the time for a $190 / day. Most chargers wouldn't do even half that.

No one is overcharging here. We should all get down on our knees and give thanks that ChargeNet have sunk so many millions into chargers that won't see a positive return for several years. It's a gift.

Because we usually charge at home, the overall cost is still a fraction of a petrol car. But even on the highway, if your car can charge fast enough, you're still ahead.

The ChargeNet maps shows it as "Under construction". I know they want to complete the Coromandel ring, but predicting dates is frought with peril. 

Nick Smith (the operations boss at ChargeNet) said two weeks ago the Coromandel Town charger was almost complete, should be done "in a few days" and was waiting something to do with metering.  It's not open yet.

I was in Fairlie over the weekend and noticed several kids playing with the ChargeNet Charger..  I wonder how long these last before they get vandalized and stop working. They are unmanned and unlocked so any idiot could damage the cable/electrical fitting.  I wonder if they have camera's installed so they can at least identify the clowns who try to do something stupid.

Update!! 

I'm told it will be up and running before Xmas at 100 Hetherington St. Here's a photo of the site I took on Tuesday afternoon. It's next to the Police Station. That's my red LEAF parked there. :-)  

I mentioned it didn't look particularly 'under way'......but was assured activity, and lots of it, is imminent.

That's annoying. Those things cost $45K.......

If you get the chance and have the inclination you might say to them they cost $50,000 and their parents won't be happy if they get a bill for damages.

Post on nzev facebook group from warehouse contact says 22kW 3 phase AC chargers going into Gore and Invercargill shops and running in few weeks.

Not rapid chargers so how much ac power you can suck out will be determined by your cars internal charging unit. Japanese leafs 3.3kw, some UK leafs 6.6 kW. Zoes can take all 22kW. ?7kW inonics,

Need own cable of course.

This is good. It will help defray the cost of ChargeNet fast charging......and let people get to 100% in Invercargill if they really need to.

I drove up to Te Kaha (Eastern BOP / East Cape) to see if there was any progress on the Horizon DC fast charger being installed there. 

The site is in the car park of the Te Kaha Beach Resort in Te Kaha Hotel Road. In the first photo, you can see my LEAF on the left. It's 134km round trip to Te Kaha from Opotiki. I got back to Opotiki with 32% (accidentally put 31% first draft) battery remaining....so another 60-ish kms. My total range was heading to be just under 200kms (196 - 134 actual and 62 estimated). 

Since I was last there a couple of weeks ago, the cable have been thrust through to the charger site and it's now ready for the concrete base and the bollards....and then the charger itself. The staff at the hotel said something happening on December 14th. I know Horizon were hoping to get this charger (and the one in Opotiki) online before Christmas. 

This charger will let EVs make a good start on any trip around the East Cape. It's only 135km from Te Kaha to Ruatoria.....and only 129km from there to Gisborne.

Not sure I'd have the patience to use them if I was driving longer distance with 3.3kw leaf. It's probably customers only with a time limit.

Wait 1 hour for 3kw electric vrs paying $7 for 10kw over 20 minutes.

I'd happy they are installing because raises profile and encourages more purchases even though most of us charge at home.

More useful for 6.6kw leafs and those more modern ev that can suck use higher amps and more phases.

Depends where you are in the country, as to who offers you what deal...

Mercury seem to be good at the moment (I switched recently) with a 20%discount from 11pm-7am for EV owners (you have to provide your vehicle reg and PROVE it though).

Before that, in my area, Powershop gave me a great peak/offpeak at a far more reasonable 9pm-6am and ALL weekend rate. There was literally only $5-$8/month difference, and I went with Mercury only because they will be a 30 day month-to-month contract so I could see how it panned out.

On my second month now, and seriously considering swapping back as I loved the Powershop app ability to break down power use over time, and the 9pm offpeak has a much better WAF for washing and dishwasher offset use than 11pm in y young family house.

Others who can get it will also recommend Flip for their ‘hour of power’ but they couldn’t take me with my 3phase meter apparently.
