iambobthefish: Made it from Whanganui to Paraparaumu Beach on a 95% charge, full air-con and highway speeds, in a 30kWh Leaf. The final 3 kilometres I had '---' battery left, and Leafspy gave me 1.2 kWh on arrival.

I know I could have stopped at Otaki, but that's not as exciting.

Drove from Hanmer Springs to Rolleston (152.7km) on a 100% charge/362 GIDs, ventilation fan and A/C, stereo, 2 adults, 1 11yo boy, and the rest of the car full of luggage (incl a spare wheel). 100/80km/hr areas mainly with a little 60km/hr. Arrived home with 17% showing on the dash and 64 GIDs/5.0kWh.

Could have stopped at any one of 3 fast chargers, but as you said, that's not as exciting!

Well with the end of the year coming, and 2019 and the promise of the new Leaf retailing in NZ I guess the big question will be price,

There is growing speculation that Nissan will price its 60Kwh version in the US at the 35k Price point Telsa staked out a number of years ago. (ex incentives) https://www.caradvice.com.au/696262/nissan-leaf-e-plus-60kwh/

This might mean we see it here for around 70K?, maybe under ? ( given the 64Kwh Kona is camped out at 75K, it can't really be any more than that )

I'm hoping Nissan really actually try with this new Leaf and get the 40Kwh here with a sticker starting with a 5..., but what do I know....

The article mentions active cooling in 2019, but I've not seen any formal announcement to that affect.

Given the sale of Nissan's in house battery division and the shift to LG Chem batteries for the 60kwh,, its seen as a fairly safe bet it will get something similar to the bolt, ( which also uses LG Cells)...

The big question is whether they will introduce LG Chem cells to the lower capacity leaf....

One page back I was asking about owners' experience with charging cables, given my own one (a Charge Amps Ray) had died.

The car dealer I bought the cable from says he's currently dealing with faults in four of the same type of cable - he's proposing to replace it with the equivalent cable from OEM Audio - assume it's this one here https://www.oemaudio.co.nz/Product-Detail.aspx?ComId=d69e4761-ed71-436b-9b8b-48e1d617c1b7

Does anyone (eg @tripper1000?) have experience with cables from these guys? I'm currently using a temporary replacement from the same brand ("EV Power") that the dealer sent me, which is working fine (even if sooo slow at only 6A!), but I'd appreciate any feedback before I commit for sure to this as a permanent replacement to the Ray. Hopefully it can't be any worse!

Many thanks.

I have an OEM 10A (standard household plug) charger but don't use it that regularly. With the first batch there was an issue where the type 1 plug manufacturing was just a fraction of a mm out, so it needs a slight lift to lock it into the socket (otherwise you'll just get warning beeps from the Leaf). Other than that they seem fairly robust and well made. I imagine the newer ones wouldn't have that plug issue.

My 10A charging cable is an OEM Audio too. I’ve used it every day since we bought the car and never had an issue with it. They are well made. The only thing I’ve noticed is that the latch part on the top of the EV plug doesn’t go far enough into the Leaf’s port such that the plug lock can engage, meaning it can be unplugged even if the lock is on. That doesn’t matter to me, but it might to someone.

Has anyone changed the supplied wheels to extend range?

The 17" wheels with wide tyres are said to reduce range by 5% compared with the default 16" wheels. Lighter weight wheels reduce energy use as can narrower tyres with less roll resistance. Low roll resistance tyres are must on EVs.

15" wheels with 195/65R15 tyres would have been the ideal for this car. Most 15" wheels are unable to fit the Leaf as there are brakes in the way. I've read they increased the brake size in Gen2 Leafs.

The fashion for big rims and narrow sidewalls puts huge pressure on car makers to use oversized rims which increase energy use.

Hub caps also affect range. Aerodynamic wheel covers can increase range by over 3% and as EVs use regen braking, heat dissipation is not as important. Unfortunately alloys are usually designed for display and not aerodynamics.

Charge Leads:

I have no experience with other brands of charge leads, but I am interested the learn that the idiosyncrasies of the Ray Charge Amps are possibly a fault that the manufacture will replace the for. Keeps us updated on the outcomes.

Wheels:

I have considered increasing the diameter of the wheels (primarily by going up 1 profile on what Nissan recommends) for several reasons:

1) to correct the 11% under-read of the speedo that Leafs are notorious for.

2) Reduce rolling resistance.

3) Improve the ride.

I don't think there would be any issue fitting them under the guards, the wheel arches on the Leaf seem a bit over-sided anyway, a little like a crossover SUV. I would have thought that for aerodynamics they'd have made the guards a lot tighter - more like the Honda Insight.

"Nissan Leaf brake system potential issue"
Flip the Fleet
by Geoff Dobson

More than 60 reported failures – including five in New Zealand – of the electrically-driven brake control unit in Nissan Leafs made between November 2012 and February 2016 have prompted EV coalition Flip the Fleet to seek more information.

“Our research has led us to believe that these failures can be attributed to faulty ‘Series-A’ firmware that is written into the brake control at the time of manufacture (or a subsequent firmware update to ‘Series-B’),” says Flip the Fleet’s blog post.

No reported failures have been found in Leafs running the further updated ‘Series-C’ firmware, the group says.

It says some drivers have described depressing the brake pedal but found braking seemed ineffective and stopping ability was reduced or non-existent.

“Our research has shown that in the case of a simulated failure, reduced braking ability is still available to the driver,” the blog says.

“You may need to slam the brake pedal hard and right to the floor to get some braking!”

Flip the Fleet estimates about 2400 potential vulnerable vehicles are in New Zealand, most still running the ‘Series-A’ firmware.

Under reporting speed is the norm on pretty much all cars (by design)

Yes the speedo standards requirea slight under-read and no over-read, but the Leaf speedo is right on the outer limits quoted in that article. AA says at 100kph it must read between 87.3 and 100 kph. My Leaf reads 88-89kph at 100kph on the GPS.

All my other cars have had a 4-5km under-read at 100kph which is fine. My Leaf has an 11kph under-read at 100 kph which is just too much (and a fairly typical Leaf error reading the forums). People think they're driving responsibly at 95kph on the dial, by in reality they're doing 84kph. It's why, I believe, Leafs often lead a snail trail.

I talked to one couple who had recently got their Leaf and they were commenting on the prolific agro ICE drivers give EV drivers on the road. I never get agro from ICE drivers so we got talking and it turned out they had no idea how slow they were actually going and felt that was the likely reason, given the windy single lane roads (SH16) they'd been driving on. I doubt it was the other aspects of their driving style otherwise they would have likely received the same agro when driving their old ICE.

^^^ Totally. I was shocked when I found out how inaccurate the speedo was on our Leaf - I think it's doing 91 at the claimed 100 so while not as bad as yours it's still unacceptably out.

I'm sure this is a key reason for the apparently bad rep that Leaf drivers have from many other drivers - the many comments I've read of motorists getting frustrated by Leafs tootling along well under the speed limit. Many such comments insinuate it's the drivers (apparently we're all hippy, environmentalist, away-with-the-fairy types!), but I think this speedo issue is at its core. Why would (and should) drivers expect their speedos to be this inaccurate?

Maybe to you, but its perfectly legal

also from an EV selling point of view a larger under-read makes range look better,
