Not everyone makes a lot of long trips.  If you do 1-2 times a year, you could just hire a car for that.  I mean you're right, the current offerings are not for everyone.  But the limitations are not as severe in practice as a lot of people seem to think.

 

 

Very true. 

I've driven my LEAF from Auckland to Bluff to Cape Reinga to Auckland....and that was just one trip of many. 

 

The Tesla guys say they drive from A to B while LEAF drivers have adventures. 

I can say there is some truth in that. 

So while some may see a car like the LEAF as being less capable than they think they require, others see an opportunity do things differently and learn new ways of doing things.

My LEAF gets me everywhere I want to go. I don't feel limited at all......and I'm having a massive time. I drove from Auckland to Opotiki today via Cambridge and Tauranga. Loved every minute.

 

 

 

 

Yes, I guess you could regard it as an adventure planning EV range and making sure that you don't have to get towed. And sure I like doing things differently and learning new ways and at the same time helping to reduce harmful emissions. I do admire the tenacity of people taking low range pure EVs on risky trips and the knowledge gained is a great benefit to future EV owners. But, if you only want to own one car, then most affordable pure electric EVs could be a bit of a nuisance after the initial buzz of things has worn off when compared with owning a 700-800km range petrol engine vehicle.

 

Incidentally, do many of you post on Facebook, the EV owners groups seem to be very active and I would recommend them as essential reading for EV owners or future EV owners.

Does anyone know if it's possible to get your local electrician to wire up a socket for EV charging that is metered via the controlled meter rather than the uncontrolled meter we have?

This comment made me think - what happens when you tow an EV?  Is there anything mentioned in the owners manual of those who own them? I realise that many of them have regenerative braking systems - could you charge the vehicle by towing it? (discount the obvious issue of the cost of the towing vehicle etc) Or will it get all upset if flat towed for a long distance (as a lot of automatic vehicles do)?

The leaf anyway goes into neutral by default if you run the battery all the way flat.  And can be towed like any car.

 

If it's not quite dead you can regen on tow, check youtube :) although it's not recommended

Call a sparkie and get a quote? 

Autolink or other EV vendors may be able to recommend an EV-aware electrician.....saves you paying for extra time while they learn on the job.

Probably not recommended because someone is almost guaranteed to screw it up. ;-)

I'd love a Tesla Model X, with the full option Autopilot. 

 

What's the legality of the Autopilot in NZ?

The driver is the driver.....whatever tools the driver may employ. So far, it's not an issue and won't be until someone prangs something.....at which point the driver is ultimately responsible for the vehicle. 

Having a nap while your car drives itself isn't legal.....and not possible (yet) anyway. :-)

I came across this article about the impact of hot weather on electric vehicles. It also has some facts about the impact of cold weather:

 

"When the heater is used in cold weather, it affects the electric range significantly more than the air conditioning in the summer.

 

Component efficiency losses occur as the temperature drops.

 

Heated garages dramatically increase the cold weather range of electric vehicles."

 

So now we're told that it's a good thing to also heat up your garage in cold weather --- ouch, it costs more than enough to heat up the house!

 

And it's also suggested that in cold weather you have to be careful about using the heater.

 

This should warn potential buyers that short-range pure electric vehicles are a real source of worry in very cold weather!

 

p.s. Significant snowy weather forecast for later this week - EV owners beware!

Out of curiosity where do EVs source heat from for heating the cabin? 

 

Do they draw heat from the electric motor and/or do they have air heating elements?

 

I'm guessing in a stop start urban setting the motor wouldn't get that warm.

They just heat using the battery's energy with an electric heating element - as Fred pointed out, EV's suffer badly in the winter. Best use your car's smarts to warm itself up off the mains in the morning before you drive.

My new house was built with attached garage insulated to R3.8 (even the door!) and adding the air of its 40m2 footprint of my 260m2 total would be very minimal impact, and easily done by simply opening the adjoining door... plus the HRV is probably pushing air through there on its way out our otherwise very 'sealed' home anyway... so I guess this is again only relevant 'depending' on your individual circumstances?

On the border of 'south Auckland metro region' snow here is VERY unlikely too 😉

Second gen Leafs actually used heat-pumps not unlike the ones installed at homes. They are much more energy efficient than normal heating element.

That's good. Can't see it being too much of an issue in NZ's climate. Could be a troublesome in very cold climates where heatpumps struggle to get heat out of the cold ambient air.

No. Firstly because it has no V8 (cool) and secondly because it would not be practical for long 1500km+ trips around NZ that I have to do regularly.

 

I do have a hybrid but to be honest it probably doesn't return much better mileage than a modern, carefully chosen petrol car from VW or someone.

 

When there is one that charges in 5 minutes, does 800km with 5 people and their luggage on board and has the size and ability of a Land Rover Discovery, I shall certainly consider it.
