tripper1000:

Do they not use salt on the roads in Japan? The pre-purchase photos of my car showed it in a snowy car lot in Japan and I assumed the salt situation would be be same/similar to the UK.

Not as extensively, and being careful about the auction house you're looking at and the part of the country it's in means you can generally avoid anything with major salt damage; or at least trust that any visible under-body corrosion will be noted on the sheet.

The three cars I've bought from one auction house have been basically like new underneath, while other prefectures show visible rusting under near-new cars as a matter of routine wear-and-tear.

Oh, they do, it's very common in the northern regions like Hokkaido.

don't we use salt in winter in the south island? (as well as the loose gravel stuff)

hey peeps - if i want to install a sub woofer in the leaf, how do i wire it to use the battery pack and not drain the 12V battery?

The battery pack is 400V, you're not running it off that. It only powers the motor and the DC-DC converter which is what charges the 12V battery. As long as the car is on, it is running off the main battery.

The Leafs 12v system will easily cope with a huge sub. Just wire it like you would wire an ICE.

The Leaf has an awesome 12v "alternator". The DC-DC converter changes the 12v battery from the main traction battery silently and steadily at huge currents. I have pulled 1kw (80 amps) from the 12v battery (via an inverter) and the voltage did not sag, staying up at 14 volts!! Few, if any ICE can do this. While many ICE have 80 or even 120 amp alternators, in truth they can only produce 80/120 amps at high RPM (e.g. >2,000 rpm), and produce paltry charging currents at idle (0 - tens of amps).

You shouldn't even need to up-size the 12v battery unless you want to run the sub with the "engine" off - but with no exhaust or engine noise, you'd only do this for anti-theft reasons.

No. Banned back in the mid 1980's due to lobbying by the AA and environmentalists.

Jase2985:

could you provide some reasoning for this?

Salt.

Generally EX UK leaf's (at least for the ZE0 & AZEO generations) are seen as desirable.

I think they get 6.6kW chargers by default. And generally better level's of safety spec (side airbags, steel doors).

Think it's unlikely you would end up with one by chance.

I don't even know the spec of the one I'm supposedly going to be looking at, just the colour and the year! So I'm prepared for all eventualities. If it's an S I'll just stick an Android Auto head unit in it and if it's an X or a G then I guess I'm just going to consider myself extremely lucky. Already got the ChargeNet fob and OBD2 scanner, so I'm pumped and ready to go!

The 40kwh model power will be fine (I learned to drive in a Corolla with like 90 HP so everything feels like a Supercar to me), I just want something that's going to last long enough to justify putting in a party battery down the line and not have to worry about the rest of the car falling apart.

The EVs Enhanced announcement sold me on the idea that I could get a Leaf and not end up with a lawn ornament when the battery degraded.

Just so you know - 40kWh is the capacity of the battery ie the size of the 'gas tank', not the power of the motor (which is measured in kW). https://www.whichcar.com.au/car-advice/what-does-ev-kw-mean

Over time the batterys' total capacity diminishes...but bear in mind that even if you can upgrade the battery at a later date...that might not be the best thing for your wallet or the planet. Consider the pros and cons of selling the car with the existing partly-degraded battery down the track, as someone would still find the range to be fine for their purposes!

40kWh cars appear to be doing substantially better battery health wise than the smaller battery leaf's. Noticeable concave up in the curve below. and generally higher state of health than similar age 24 kWh & 30 kWh cars. Latter is to be expected bigger battery, means less cycles (and less need to do max range charges to 100%).

https://flipthefleet.org/resources/benchmark-your-leaf-before-buying/

If we did model the decay linear. decaying to on average say 88% in four years, means about 3 percentage points lost a year. means the car should get to 16 or 17 years before it gets down to 50% SOH.

Suspect the car will be approaching end of life at that point, but might be able to eeek out a few more year's. doubt it would be worth putting a new battery in at that point.

Key issue with battery replacements at the moment is the world is battery production constrained, and many governments are paying rebates to those who buy new EV's, (and selling new also allows automakers to avoid thousands in fines. Effectively a $10k+ incentive in many locations to put a scarce EV battery in a new car, rather than a used one. Means that stand alone battery packs not in cars are likely to be very expensive for some time.

Of course this could all change in 10 -15 years.

The real catch-22 is the improvement in the battery pack density (say being able to fit a 60kwh - 70kwh battery pack to a Leaf) without it destroying the value of your existing pack as an upgrade option for someone else's Leaf to help ease the cost.

I figure I'll just try my best to look after it and see how long I can make it last.

Leaf owners warned to be careful driving the new Transmission Gully road as it drains batteries faster than the old SH1 route:

As you can imagine the story is a stonking beatup

""When I drive to Wellington I get there with more than 60 per cent battery at the end, but [over Transmission Gully] I arrived to Wellington with 52-53 [per cent], which is quite a big difference."
Laura said she previously did the round trip to work and back on a single charge, but she would not risk that now.
She was surprised there was not a rapid charging station in case people - particularly out-of-towners - got caught short."

How about she find somewhere in Wellington to charge before she came home..

.. Or have an EV that will happily do more than 110km daily..

. Or shock horror, she could continue to drive the same way she always did, this time with much less traffic... no one has taken the old road away....

There is some value to the warning though, a similar thing happened to me when the Waikato expressway opened bypassing Huntly. Previously the round trip I did from Hamilton to Ohinewai and back fortnightly was easily done in my (at the time) 2013 24kwh leaf with 77% SOH. Afterwards The trip got marginal in the summer and I needed to stop in the winter. Luckily there's a free charger at Taupiri and it's still faster going the new way and stopping for a few mins on the way home.

I have upgraded to a 40kwh leaf now so no more stopping on the way home :)
