good idea, use leafspy and not look at the bars

You'll find most car manufacturers add a huge amount of dampening to the temperature gauge on vehicles. People get all panicky when they see the gauge moving. You'll see the gauge sit at the low end of the scale, then after a small period of driving, make it's way to the middle, where it won't move from again. If your vehicle overheats, by the time the gauge moves up to the red, its normally too late.

I used to modify the dampening resistors for people who towed - once adjusted right, you could see when the thermostat opened after a few minutes of driving, and under load or going up hill you could watch it move up, and then back down again when the load came off. Useful if you were used to looking at it, worrying for someone who wasn't and saw the needle start to move as the climbed a hill.

Not so common a modification now days as people just get scan gauges or obd2 readers and watch the numbers themselves.

It wouldn't surprise me if Nissan had put some form of similar dampening in the Leaf gauge, albeit software driven I would expect - most people just look at the gauge and see "middle" and don't give it a second thought.

The large mass of the battery has a huge amount of thermal inertia, so there is a lot of "natural" damping. I find the battery doesn't follow the changes in ambient temperature very quickly.

 

I have seen the temp gauge swing up on long trips with multiple fast-chargings.

 

There probably is a scale of degrees per bar, if you google it.

I found this image somewhere, possibly a hundred pages back, haven't checked accuracy myself but seems legit. I keep it on my phone for quick reference.

 

 

 

 

I find the temp gauge does align with outside ambient after some hours of sitting, i.e it's cold in the morning. About 12C these days (live in Qtn). It is super slow to change though which as mentioned is likely just the massive thermal mass.

 

Charging at 10A EVSE I do not see any temperature rise whatsoever but consider that the I^2R heating effects at 10A/230V is less than 1% of at a 40KW+ fast charger. 

 

 

 

Also I use a Teison EVSE that is configurable between 6/8/10/12/16A. It has the CEE caravan plug but then I have a CEE to 3 pin 10A adapter (with 10A MCB) so I can use the same single EVSE to charge at 16A at home or take it away on a trip and charge from standard 10A socket. The combination cost me around $350 in total. The Teison also has timer delay if needed but I prefer to use the car timers for that.

 

 

 

Mines a 2017 40KWh 86% SOH, through EV City. I was going to directly import but the timing was bad with clean car scheme announcement and Japan auction prices immediately went skywards.

Not sure if this has been discussed earlier, but found a youtube clip from EVs Enhanced where they have come up with their own Battery for the Leaf and has Active Thermal management

Quiet and boring in the car market... Created today alternative budget convertion from Japanese to English for Leaf AZE0 Carwings headunits: 2012-2014: QY7214; QY7224 (with camera button, Bose) and QY7254 (e-NV200). Maps out of scope. All interfaces in English. These three headunits - are up for grabs ..

Hi all

Wondering how feasible/reasonable a Leaf might be for us as we tend to do a lot of long distance driving every weekend (about 66km return). Wondering if the lead will hold its own for years doing this.

In addition if it is feasible, we too are currently researching 2nd hand, some do come imported from Japan so wondering how getting the language conversion would be done. Another thing is does it creep or is am option to turn this off(fiancée is a manual driver and hates automatic but will be willing to switch as long as this can be done for maximum WAF score)

Lastly what's a good price for one from the 2016-2018 year ranges I do see it linger around the 34-38k range, it sounds good but as always I'm skeptical.

Blue Cars offer a translation service for about $450 from memory. Other EV specialists from around the country should be able to help you out, it's a fairly standard offering by now. 

 

The biggest change coming from a manual would be the lack of handbrake, IMO. I'm specifically avoiding anything with the footbrake (yuck).

foot brake for me is fine, i only use it for parking anyway. It doesn’t creep at all, without your foot on the gas pedal it doesn’t even move to the point where I can forget I’ve turned it on (and hence turn it off my mistake, thinking I need to turn it on…)

 

my leaf (2014 Gen2 with around 81% SOC tho I think that just dropped) has a roughly 120km-125km range, so a 60km round trip would be easy, and comfortably charge overnight. I can get a near full charge (20 to 100%) from an 8A plug in the off peak time from 9pm to 7am.

 

I’m on Waiheke, so most of my trips are shorter, and I’m charging once a week at the moment, as both of us are working and we’ve been organised and done a load of forward meal planning, so I’m not going to the supermarket as much.

 

we did a “big” road trip around coromandel in feb, and mostly it was fine, bit of anxiety going from Thames to Bombay. Head winds can be a killer, too. If we had 170km range (more normal for a later 30kwh model I think?) it’d be fine. Got a few posts on my blog about it (url below)

I'm a recovering hoon so I'm going to feel lost without the yank stick on gravel 😆

 

My most extreme use case is still the odd ten hour day trip, but that usually involves at least one or two stops and doing it somewhere with bathrooms and refreshments usually means you're near a charger anyway. I'm sure a 40kwh driven conservatively will be able to handle it and I probably need to manage my fatigue better anyway.Doing the SH25 loop on the Coromandel or a jaunt down to Taupo should be well within its grasp.

 

Plus I'm not in my 20s anymore and my days of doing full Bathurst-length stints in a beater Corolla to see a snowstorm or for a Sunday fish and chip run are (perhaps sadly) behind me.

the "bars" on the leaf was somewhere halfway in the range of bars ...

 

leafspy said 15C

 

don't trust the bars!

very easy to use the foot park brake to drift the car


one of the easiest car to initiate a drift (and terminate drift as car won't fly everywhere either)

I was not expecting this to be a marketing angle for the Leaf, but Nissan has us covered:

Now I just need the 40kwh Leaf, the empty warehouse and, you know, the skill. Two of those things are a lot easier to get than the other. 

 

I wonder if the old McDonalds trays under the rear wheels trick works...
