Good news 

 

It will be interesting to see the results of the application from EV Christchurch.  I have found my soh bounces up and down like a yoyo as well.

 

I am sure there are many of us with the technical skills who could apply the patch if made available legally.

That's point about the EU rules. It is available legally. Plus, there is no warranty to void in NZ on an imported LEAF.....

Keen to see how this plays out, and also what effects it has on back-to-back DC fast-charging. A 30kwh car should get me most places I want to go and back on two fast-charges.

I spoke to GVI about the patch last week and they said they will be bulk-emailing all their 30kWh customers as soon as they have it themselves.

https://www.greencarreports.com/news/1116139_2018-nissan-leaf-electric-car-is-there-a-fast-charging-problem

 

This article discusses whether the 2018 Nissan Leaf has a fast charging problem. It seems that, after the first fast charge. if you do a second or third fast charge on the same day, the charging rate slows down considerably. The above article explains that:

 

The problem stems from Nissan's decision not to use a liquid-cooling system on either Leaf's battery. Instead, it is air-cooled, much like an old Volkswagen. When the battery can't dissipate heat fast enough when charging, its capacity can start to degrade.

 

Rapid charging heats the battery more than does driving or ordinary 240-volt charging. On a long trip, driving between fast-charge locations doesn't give the battery time to cool sufficiently between successive fast charges.

 

Which once again shows that you really need a liquid cooling system for the battery if you plan to travel long distances in one day in an electric vehicle.

 

https://www.bbc.com/news/business-44575399

 

In this article, some electric car buyers claim they were misled by Nissan. Here's an extract:

 

Owners of Nissan's new electric Leaf say they were given misleading information about the car before buying it.

 

They say charging the Leaf can take three times longer than claimed on Nissan's website.

 

Others are unhappy that the range on a single charge is not as good as the 235 miles (378km) they were promised.

 

Nissan admitted that charging times can vary, but denied there was a problem or that any customers were misled.

 

The Advertising Standards Authority is now considering whether to launch an investigation into the issue.

 

I think the 2018 Nissan Leaf has a range of about 250 km, so buyers who thought they would get 378 km perhaps didn't do enough research before they bought the car?

Vehicle manufacturers using unrealistic models to evaluation fuel efficency has been a problem since they started sticking MPG figures on ICE cars,

 

it has carried over into EV distance ranges, but it does appear that the newer standards are better when compared to the "real world"

Well a range of 250km would let you drive dunedin to chch with one charge on route assuming that you left home with a full battery from slow charging overnight before you set out.

 

Auckland Wellington is 640km so 2 charges on route maybe

 

There will be those who want multiple charges on the same trip but for me driving 500km with a decent break in a single trip is questionable from a safety point of view to the passengers and other road users.

 

 

 

(I get a little frustrated at online comments when people say they wont buy an EV until it can drive from wellington to auckland without stopping. I wouldn't want my children in your car is you think thats sensible. Would be interesting to see a court case where someone drove that far without a break and made an error/crash))

I'm with @afe66 re need for breaks.

 

However, it's nice to be able to determine when one takes those breaks, without being constrained by location of charging stations. Further, duration of breaks is another consideration - ideally not affected by number of cars you have to wait behind to charge.

Yeah although as the density of chargers improves on keys routes, you will simply be able to drive to the "next town"  rather than have a few fixed points.

 

C.f SH1 between Wellington and Auckland, It was only a year or so ago that the central plateau was a wasteland for charging with one at Taupo and then Mangaweka, but now there is Waiouru and Taihape is coming soon, National park and Tauramanui and Ohakune are coming, ...

I agree with the need for charging locations.

 

Mind you, as far as I can recollect I havent read much along the lines of I want an ev but not sure about the number of chargers at Taupo.

 

I think poeple get too hung up on the range stats. Probably because of all those tv ads which show cars driving up the side of mountains/accross fords when actually its used to take the kids to hockey practice.

 

If the distance to more than 400km, I'd probably just fly and get a small car at the destination.

I may be coming from minority viewpoint - have owned Leaf for ~2y, can do ~100km on highway in summer, no desire to have to plan such that I'm down to 10 km by the time I reach a fast charger. What if there's a big detour etc. Obviously unlikely, but hey, I've had car insurance for ~15y and yet to make a claim, and I'm not planning to cancel my car insurance. Hence I'm keen on 400km so there's plenty of buffer (insurance).

Last weekend I went to Hastings (315km each way), along the route were several chargers.  But, because I only have a 24kWh Leaf which I regard as more suitable for commuting, I left it at home and rode the motorcycle instead.  I know that I could have done the trip in the Leaf, but I would have had to stop at a fast charger about 4 times between home and the destination - not stopping to charge from 0% to 100%, but still stopping and waiting for a charge.

 

If I was buying a new EV I wouldn't consider the 40kWh Leaf, but I would consider the 2019 Leaf with 60kWh battery.  Instead of stopping for 4 or 5 times to charge (like with my 24kWh), I could stop to charge/rest/eat/pee and then carry on to my destination.  The convenience difference is really large, IMO.  The 60kWh Leaf could even get from home to Wellington with only one stop and I wouldn't be keen on driving any vehicle that distance without a break along the way.  As long as there are chargers near food/toilets along the way then I don't see much reason why a ~60kWh EV would be inconvenient to use for long trips.

 

Flying instead?  If I lived in Auckland and wanted to go to Wellington or Christchurch then sure, flying would be cheap and easy.  But from Morrinsville to Hastings?  I could get a lift to Hamilton Airport and then fly to Napier Airport and get a lift to my destination, no real issue with the logistics there.  But flying to the smaller airports is MUCH more expensive than driving a car, it is nothing like the cheap price of Auckland-Wellington.  In fact, there isn't even a direct flight available from Hamilton to Napier, I'd have to have a stop in Wellington.  The total travel time would end up being longer than driving a 60kWh EV and the total cost would be several times as much.  If I were to fly from Hamilton to Wellington and then rent a car for a few days then it would definitely cost more than driving down, car rental isn't cheap.

 

Comparing driving a petrol car to an EV:  For commuting the EV is cheaper.  For long trips a 24kWh car has many drawbacks, a 40kWh car would be better and a 60kWh car would have negligible drawbacks.  The 60kWh EVs will be more expensive initially, but as they come down in price they should make a very good alternative to a petrol car.

It will be interesting to see if that happens (much) ....

 

posit, the 2010 original leaf had a US list price of 32K, (24kw,) (exc credits etc) in 2018 the 40kw leaf has a list price of ........ 30K US,

 

2K in 8 years is not much of a drop-

 

Car companies dont make money selling cheap cars, they make money selling you more "product" at a similar price point,

That's really only 200km each way - a trip to parts of the Coromandel will set you back that easy. 

 

Having said that, range will become less of an issue as charging tech evolves and batteries along with it. A 30kwh Leaf would be great if I could get to the skifields and back from Auckland with two charges along the way, or if I could charge it in the same time it takes to fill a car, but unfortunately we don't have either just yet. We're getting close, but we're not quite there yet.

I don't see a need for a price drop.  The Nissan LEAF is priced like an ICE family car already.  We upgraded from a Honda Accord to a LEAF.  Its shorter but larger inside and a nicer ride:

 

Nissan Leaf 2018 30k USD

 

Honda Accord 2018 is 28K USD.  (basic, small engine, cloth seats etc).

 

I think this is the price range for this kind of car, regardless of EV or ICE.

 

It really comes down to range for us, we didn't need a long range car 99% of the time so an EV made sense.  If you are doing long drives between locations on a regular basis, and you don't want to stop to charge (or can't), then an ICE makes sense.  As the range of EV's improves, more and more people will opt for them, but the car companies will continue to try and sell you 4 wheel drive mountain climbing cars with aspirational landscape videos :) We are a long way from EV's replacing ICE cars for all use cases, but maybe not that far from meeting the needs of 75% of people within a few years.
