Glad you found the issue @HarmLessSolutions! And thanks for the tip, good idea to replace it after x years. Our is from 2016. Just tested it by putting it in ACC (not in Drive) and turning on the heater. Within 3 minutes the voltage had dropped to 10.4v, and the charging kicked in. According to some other posts that's way too short, it should last for 10-15 minutes. So time to replace it!

A different question, I'm using our Leaf as a backup 220v generator by connecting a 220v inverter to the 12v battery & putting the car in On. Works like a charm, but the one issue is that I have to disconnect the 12v plugs from the car. This is inconvenient, causes small sparks, and resets the car (e.g. trip meter). Also this is not something my wife can do.

Think the best solution is to connect 2 Anderson plugs permanently, but I don't have the gear to make them; premade they are about $60 from Aliexpress.
Is there any other alternative?

@boland, We haven't gone down the 240V inverter route with our Leaf but it has gained a stay of execution since I found that the Leaf is the only EV on the NZ market currently that has bidirectional charging capability and the idea of V2H definitely appeals. Even with a degraded battery the storage potential of an older Leaf is massively cheaper than investing in a home battery system. We're just waiting for the tech and regulations to come up to speed regarding V2H/V2G, and the price of bidirectional chargers to come down to a sensible amount. I realise too that our present Leaf is probably a bit too old to be a V2H capable model unfortunately. Anybody out there care to confirm or comment in this regard?

Worth mentioning too that the battery we changed out of our 2012 Leaf recently wasn't its original one. The car delivery company had to replace the battery as it came 'off the boat' in July 2014 with a dead 12V battery. And it was replaced rather than recharged as the battery it arrived to us with was a NZ new one.

Anyone has recommendations for a 12v battery replacement? It looks like an AGM (deep cycle) battery is recommended over a traditional car battery.

Preferably I can pick it up in Lower Hutt. Century has an 58Ah 12v AGM battery for $389, but Century gets very bad reviews on ProductReview. However, that site seems to get bad reviews for a lot of things....

For that price you're getting into Li-Ion territory. https://www.thebatterycellonline.co.nz/Lithium_Batteries.html LiFePO for safety and long life?

The north american Tesla plug (socket) on that adapter is extremely unusual in NZ. Pretty much restricted to the handful of used import Tesla's from japan (where that plug type is used).

Model S & X sold somewhat recently in NZ used a modified type 2 plug (backwards compatible with regular type 2 for AC charging, and capable of doing DC charging via the modifications).

Model 3 & Y use type 2 CCS.

What you are likely after is a type 2 to type 1 converter, so you can change you Nissan leaf at public charges with type 2 tethered cords. For example:

https://chargemaster.co.nz/products/32a-type-2-to-type-1-adapter-1

I haven't used one in this direction, but despite being against WorkSafe guidelines to use an adaptor, there is no reason it should not work fine. Note that if you are eyeing up some Tesla destination chargers, it depends on the version (and the setting of an internal switch), if they will charge non-tesla brands of car.

Also note that they are AC only. No good for DC charging (i.e. super charger).

I had a similar adapter but in the opposite direction (type 1 to type 2) back when the bulk of public AC EV charging was type 1 tethered, and I had a UK import BMW i3 with a type 2 socket. Mine worked perfectly. Mine had a plug & socket with 500mm of cable between them. Would have resulted in less port strain, but did leave the socket plug paring hanging close to the paintwork.

Thanks for the correction (type 2 to type 1 converter).

No plan to use Tesla destination charger but the actual reason is I got a Leaf and have booked Model Y. For model Y, I want to install the fast charger may be outside of the house so thinking of using the same charger for leaf as well as Model Y. I hope type 2 to 1 converter will do the job.

Also, you mentioned it is not good for DC. I have a solar setup at home, is it advisable to install tesla fast chargers running on solar (DC, isn't it?)

I switched from a 2017 Outlander PHEV to an imported Leaf of the same year last week. A trade down in value (the dealer paid me) but a trade up in many other ways. The PHEV served us well, but was just too big and I much prefer an EV.

No immediate questions for the thread, I've figured the centre console menus out with a translation app, but I'm likely to ask something eventually.

Firstly I am not an electrician, you will need to use an electrician to install this stuff, so might be better to get advice from them.

As a general note, with regard to terminology, The term fast charging is typically used for DC charging at 25kW or above.

AC charging for your Tesla will be at about 7kW, or about 11kW depending on if you have a single phase or three phase supply. You leaf will charge at about 3.6kW or 6.6kW depending on what version of they car you have. Charging at sorts of speeds will charge most EV's overnight. A domestic socket will charge an EV at about 2kW, which will take more than overnight on a big battery EV.

Unless you have a very special use case, DC charging at home is unlikely to be viable. Looking at $25k in hardware + install.

https://www.ecogeek.co.nz/shop/deltadcrapidcharger

On solar, typically one would use an inverter to turn the power to AC, and then the charger onboard the car to turn it back into DC.

Technically skipping the AC step would be more efficient, but the tech to do this isn't mainstream, and is likely a lot more expensive and less flexible than just going the AC route.

https://electrek.co/2023/02/14/dc-to-dc-solar-powered-ev-charger/

You can get EVSE's which have smarts built into them to get your car to charge at times when you would otherwise be exporting solar power.

https://wallbox.com/en_nz/energy-management/eco-smart-solar-ev-charging

https://smartevchargers.co.nz/shop/wall-mount-ev-chargers/eo-mini-pro-2/

On charging both a type 1 & type 2 EV with the same charger, Best practice way to do this would be to install an tethered EVSE with a type 2 socket, and to swap the entire cord (type 2 to type 1 / Type 2 to type 2) when charging different socket type EV's. This is because the worksafe guidelines don't allow adaptors that are not supplied by the car manufacturer. See bottom of page 11 here:

https://www.worksafe.govt.nz/dmsdocument/5169-electric-vehicle-charging-safety-guidelines-2nd-edition

https://www.worksafe.govt.nz/laws-and-regulations/regulations/electrical-regulations/regulatory-guidance-notes/electric-vehicle-charging-safety-guidelines/

I only have one EV, but think it would be best to have a EVSE for each car. Sharing a single one sounds like a chore. You can get stuff with load sharing etc, is you are worried about overall capacity. Obviously this will cost more, but if you are already getting a sparky out, I think it would be worthwhile.

And as a general note the Gen 2 Tesla wall charger has issues charging other brands of EV. Get gen 1 or gen 3 if you go the tesla EVSE route.

I had my car converted to English as soon as it got it (the prior owner had already had the dash converted, but not the entertainment unit). Was worth the cost for me as I dislike cars with screens in languages I can't read. Example service provider:

Thanks. I've been to The Battery Shop and the guy confirmed the battery needs replacement.
He put in an N55MF Yuasa: https://www.thebatteryshop.co.nz/store#!/N55MF-Yuasa/p/385870433/category=56163169

He recommended this one over a standard car battery as the Leaf treats it more like a deep cycle battery than a traditional battery which is mainly used to start an ICE; which makes sense.

AGM would be hard to fit.

Just replaced the original Ecopia 205/55x16 tyres at 56,000 km on my 2019 Nissan LEAF +. I was quoted $320 each to have the same brand fitted, so asked if there was a cheaper option.

Today, had 4 x Firestone F01 'Fuel Fighter' 205/55x16 tyres fitted at my local Bridgestone at 4 for the price of 3, total of $819.00 (works out at $205 ea). Very nice driving, quiet, I'm very pleased with them.

Suzi auto in oz has got 50kWh packs up for order now. Similar deal to start EVs enhanced were saying that they need the enclosure and will replace the cells to do the upgrade. His post sounds like they are offering this over here as well and their pricing is $18k aud +gst.

That is about 340kms range. I understand from that post

$18k AUD = ~$20k NZD + 15% GST = $23k
Not clear what chemistry is used either. and he will need the case. Will be hard to resell a bunch of loose batteries.

Suppose that 50kW pack is quite a niche market. My 2016 Leaf would be worth less than that.

Guess I need to wait for 30kW or perhaps 40kW replacements becoming more attractive in NZ.

Based on what he's offering warranty wise I'd say it's probably not far off the original leaf packs and there won't be any cooling changes made. He doesn't mention what they are doing with the cells being removed from the packs to make these either.

EVs enhanced are already saying they can package your removed cells to use elsewhere, at that price for a home battery and car upgrade it wouldn't be too bad if you were in the market for both of those things. 40 or 50 in a leaf I think would be fine, the 30 is fine for most of our uses but having a 40 would give us some overhead for the kff trip out of town and use the chargers at my work more often. Then again at this price we could sell the 30kWh and pick up a 40kWh leaf and have a lot of change.
