Just wondering can anyone tell me how you can tell if the charger is mode one or mode two. I was told to make sure it was mode two so that it can charge in a normal socket in a NZ house. Thanks
You mean a Japanese exported I-Miev, at Japanese domestic spec? - as all cars for all global markets were made in Japan.
Good question, According to wikipedia (https://en.wikipedia.org/wiki/Mains_ele ... by_country
) Japan amazingly uses 100V mains domestic, which would translate to Level 1 charging. NZ, like the UK uses 230/240V - so unless the car is equipped with dual voltage capability, i cant answer it. The 10KWh model was Japanese domestic only, and who knows what on-board charger setup its got, especially as they use 100V mains. So, i'd be led to believe the wall charger won't work (whether a NZ supplied IMIEV charger would work is another question), a Level 2 wall charger going J1772 (Type 1) to Type 2 may or may not work, but the CHAdeMO charging would work, as it's a defined standard. Personally, i'd assume it will not work until you can test it, and then return it if it doesn't work - but if its in Japan, only being sent to you if you buy - i'd look elsewhere. Bottom line is that it is dependent on the cars internal charger. The US spec cars are compatible with Level 1 110v and level 2 240v via the correct charging cable, but that does not mean a JDM car has that functionality - although the first cars tested in the US were JDM spec, and they must have charged them somehow - so it poses the question. I couldn't tell you if my UK spec car would work with Level 1 110v domestic, but I know that the OEM supplied EVSE wall charger would not work.
So to summarise (and be happy to be corrected):
1. The EVSE wall outlet charger supplied with the car in Japan will not work in NZ (it may be able to be modified, but if the car itself cant take 240v, then it still won't work)
2. ChAdeMO will definitely work
3. L2 charging via the typically installed 240v charge points may or may not work, depending on the charger setup in the car - and that's the biggest issue for you, as most people with EVs I know utilise this method of charging.
If the cars on-board charger can handle 240v, then 1 and 3 become possible. If its 100v only, sadly you'll be very limited.
If you were adament, you could step down a wall outlet to 100v using a transformer for 230-100v, and swapping out the supplied charger plug for a NZ wall socket, but that would be somewhat pointless, as you'll be converting an effective Level 2 voltage down to level 1, and doubling your charge time.
If you use 240v domestic mains power, then that domestic mains is L2 by default, and a 3.5-4h empty to full charge time on a 10kw/h pack at level 2 (charging at 3.3 KWh/h, and then slowing as it nears full adding another 30-60 mins).
I've not seen any of the 10KWh packs mentioned before, but from what i've read, it's a different form of Li-ion battery suited to more frequent rapid charging (CHAdeMO) - so a car designed for shorter overall range, but repeated recharges. Never seen one of these in the UK, or any Japanese grey import IMIEV here in the UK. However, I have seen Japanese grey imported Leafs being used in the UK, and thats a similar situation to this one... and they must have got them working somehow. Have a read of this, it's quite pertinent for you: https://samholford.github.io/leafguide/"An original Nissan EVSE (15A) from Japan needs modification for use in NZ, either by replacing the Japanese plug with a caravan plug, or by faulting it into a lower amperage (both should be done by an electrician). Replacing the Japanese plug directly with a standard NZ plug will cause overheating and melting of your socket."
If the 16KWh pack is rated for 70 miles, then a 10Kw/h pack calculates to 43.75 miles at full. Not accounting for winter drop, degredatory losses over time etc etc.
I would guess that this pack was suited for Japanese urban use, whereby the car is only moving at 10-30mph for most of the day, in places with readily available rapid charging facilities. Taking a car with a 44 mile range out of that environment requires careful consideration of intended use, as you will be extremely limited with the small maximum range - though having said that, if its a second car local runaround, it may still serve you well for most of your local journeys.
I'd not be hesitant about the pack integrity, as the mileage is low - but I'd be wary of buying a car with that sort of range, as I find the 16KWh pack only just enough. For highway travelling, you are extremely limited indeed, perhaps even prevented, as at 70mph, I'd estimate the range at no more than 30-35 miles at best - put the heater on in winter, and thats going to plummet by about 25-30% at a guess..
That car equates to £7k (OK the £ is very weak at the moment) - but a domestic supplied vehicle with a 16KWh pack at that age and mileage would be about 20% cheaper here... but i dont know the NZ used car market and tax situation.
