RAC states 80km range for imiev
http://rac.com.au/news-community/enviro ... real-world

I'm currently getting round that now in 2011 imiev. Travelling at 100kmh on Mitchell Fwy to UWA / RAC DC Fast chargers

72km this morning. 5.6 deg C.

http://www.goauto.com.au/mellor/mellor. ... CA001D8553
"real-world city driving range is closer to 100km"

"Australia’s i-MiEV – including its battery – will come with the same five-year warranty as the rest of Mitsubishi’s vehicle range, and the company says the battery should retain 80 per cent efficiency even after 10 years."

mitsubishi might have a class action on their hands as it seems that the battery might only retain 80% efficiency after 5 years.


This 2010 imiev gets 80km range with heater on. I don't use heater or AC normally

Larry is now showing around 130kms on the GOM after battery change. Very good considering the hilly terrain he has to go through...

Sounds like the range difference between the 2010 and 2012 i-MiEVs is mostly the age of the battery then.
Or is Larry's replacement battery actually different from the originals.
We get about 100km from our 2010 without the heater on and without going over 80kph.

Tesla model X should be out by the time the warranty runs out, then the battery can go on our home solar system.

I don't have 100% confirmation, but I am very confident that Larry's new pack uses LEV50N cells. They have been in production since mid 2013 and replaced the LEV50 cells. The battery has improvements in performance but they are still a 50Ah cell. The fact that the car needed a software update compounds this theory.

Pretty sure there is changes between 2010 and 2012 models, but I think they are more of a software nature. I find the 2010 drivetrain noisier than the 2012's, and it sounds like the software is more refined for less noise. Don't believe that batteries are any different.

Given that the range meter on my car has read anything from 60km to 160km RR depending on the last 25km or so of driving befor recharging.RR gauge is a hard thing to go by.

I would say the 2010 models are a small percentage less efficient (perhaps 3-5% at most) but the most part would be in the AGE of the batterys or more so they have had longer for people to abuse them. As I'm sure there are some way more healthy 2010's than others.

In the generally hilly areas I drive in Brisbane and up the coast in the hinterland. There is never a time when I don't get a solid 100km - 110km range. This is leaving a good 20 - 25% SOC (self imposed rule) after completing the 100km. I guess if I had to give a average reading that my RR gauge comes up with about 135km is a common number.

I think the new lev50n would be a better cell if your going to be giving the car some stick (as in high C loads) Reading a little about them it looks like they had some improvements in there ability to retain 98% of it's rated capacity even at 6C!. So if some one had a lot of big mountain climbs or sustained 110kmh driving was common. It might result a bit more range over the stock lev50's.

I should of mentioned that the exact same running for him on the old pack yielded around 80km RR.

So an improvement from 80 km to 130 km. I think the difference is almost due to the lost of capacity of the older battery. The battery will not retain 70% of it's original capacity after 10 years if it is always at more then 25 ºC.

My 2011/4 i-MiEV is now 35 Ah. Don´t have the range of a new one, for sure. My maximum range remaining given by the car is now around 130 km (100% SoC with less then 100 Wh/km consumption in the last 20 km).

With 140 Wh/km consumption, then I will only have 80 km of range.

This is my first winter with my 2010 model & an 80 km range hasn't been unusual whereas over last summer I was getting around 100 km range. It can get on the cool side here, with daytime temps in the lower teens, whilst overnight it can get to -3.

It'll be interesting to see, given the warmer weather is coming, what typical range I get.

Hi David
Do you have canion
Do you have a cell that is lower that the rest when down to 4 bars ?

I did get the program, but then I discovered I needed to buy some gadget to plug into the car. So I never ventured any further. Plus I can't now recall what the gadget was

I can happily say that, now with the warm weather back, so too has my range. I'm now getting towards 100kms again which was what I was getting prior to winter

And thanks to Gabz I was able to run ConiOn. I'm guessing the battery status is looking well...

It's looking very well.
The guys in Queeenland and WA don't get the colder weather that sees our range drop so we don't hear about it much.
Mine (DIY LiFePO4 12kWh pack) drops from 83km to 72km during mid-winter.

Thanks. It's reassuring to know the batteries are in good condition.

Yeah my range probably dropped by about 15kms over winter. But with the day temp now in the low 20s, the range is pretty much back to where it was last summer.

I also don't have the eco tyres, so I've been told I'm probably missing another 10 kms range as a result.

Hi, i DAVID; Haven't seen your mitsu around the Nock, but keep your eye out for a silver Daihatsu Sirion missing a tailpipe being driven by Methuselah and emitting a strange whining sound.(the car, not me)

Please to meet you neighbour Image

I've had mine for just under a year now. If I am out in it, it's usually to go to Woolies, IGA, or Bunnings. Occasionally I'm in Kearsley, where my mum lives, otherwise I'm in Aberdare.

I have seen the occasional Sirion around but I've never look for a missing tailpipe. I will in future. Meanwhile the whining sound is pretty normal for me   Image

We can see there is no cell with major problems. If there was, then range would go down rapidly. But that doesn´t show how much less capacity the battery have. For that, you have to see how much kWh it has going from 100% to a low SoC.

OK, thanks. So which menu on CaniOn do I use to check this with?

"Mitsubishi Motors estimates that after 5 years the main drive lithium-ion battery will degrade to approximately 80% of capacity and to approximately 70% after 10 years of usage. Like other commonly used lithium-ion batteries, battery capacity will decrease after time and with use. This type of decrease in battery capacity is normal, and is not indicative of any defect or failure in your main drive lithium-ion battery.

All right here is a riddle for you all...

I took off from Cessnock with 80 kms on the guess-o-meter. Arrived at Maitland, after a 37 km trip with 82 km on the guess-o-meter. Needless to say I was very impressed.

By the time I got home, driving the exact same distance, the guess-o-meter had dropped to 37 kms!

Can anyone explain this? BTW the "fuel gauge" was at 1/2.

My understanding is that the GoM estimates based on your recent driving. So to explain the above...

To get to Cessnock you had to drive up a hill. So at Cessnock the GoM reckoned that you'd get 80km further up that same hill.
You didn't keep on driving up the hill, you drove to Maitland - 37km downhill. The GoM was now basing its estimate on the most recent driving. Of course you can go further downhill, so it said you could go 82km at that rate - even though you had used up some of your battery.
BUT - you didn't keep on going down the hill, you turned around and went back up the hill again! So when you got to your destination it was estimating that you could only go another 37km up this hill.

So the GoM is handy if you keep in mind exactly what it is. But the fuel gauge is better.

Yep guess-o-meter looks at the previous 25kms of driving to determine the value.

I have driven a few times and lost a couple km's only due to changed driving style...

It's mostly downhill to my job (28km away) and I tend to use ~15km on the range estimator going in, then ~35 more on the way back. The only time I've ever seen my number go over 80 is when I started at full charge and went down the fairly steep hills towards work - I was up to 85 for a while.
