At first a 100% charge would come up as 160KMs available. The last couple of days it is coming up around 135, similar to what an 80% charge should be doing.
Does anyone know if the LEAF learns from your previous trips?
How are other people going?
UPDATE - Did some more testing. Charged to 100% and reset the odometer. When I first started it read 130 available. But after I drove about 5KMs it jumped up to 145 and soon after it was 160. I drove about 30KMs and still have 130 available so clearly everything is working fine.
I'm guessing it averages your trips and tries to give you a realistic estimate of a full charge. If that's the case it's pretty cool!

I ignore the driving range and look at the charge time . That is the true gauge as to how much driving you have left. It looks like we are getting 10kms per 1/2 hour charge.

Interesting! So you look at the TIME TO 100% reading to gauge performance?
So to do this you charge to 100%, reset the trip and check how far you've gone when it says 30 min to 100% or 2 hours to 100%?

Still getting used to it - 6 weeks old and about 1,100 kms. Analysis might be easier if we didn't live on a hill ! My understanding is that the range prediction is based on what the car has done in the recent past. So we find that if we have come downhill to get home, it will predict a greater than real range. Conversely, if we have had to climb the hill ( about 700 feet above mean sea level ) to get home, then the predicted range will be an underestimate ( unless we continued to climb a further 700 ft ). On the all-electric Vectrix motor bike, we used to refer to the predicted range as the ' Guessometer '. Because of the ' hill ' factor, I set more faith in the battery level indicator.

You must have a partner who doesn't insist on using the heater

I just drive normally and use the climate control most of the time. I safely get 120 km range. Interestingly if you look at the energy consumption screen, the A/C for just cooling uses very little electricity - it's the heating that is the real hog for electricity. Like running an electric bar radiator at home.

The estimated range depends on your recent driving style. Attached is my latest record of 193 km after a 100% charge - but the actual range was less.

I have had 193km but only on eco without air con driving down hill :-)

Recently did a trip where I would estimate 85+% was highway driving, cruising in ECO at 100 k.p.h., with no air-con.
Set off with full battery ( this happens automatically when you select by-pass charging timer ), with the ' Guessometer ' showing a range of 135 kms. ( normally around 170 kms ).
The round trip was 66 kms, at the end of which the Guessometer showed 31 kms.
Whereas, with full battery, in ECO and no air-con and careful city / suburban driving, no ' hooning ' away from stop light, I have covered 130 kms, with Guessometer showing 30 kms remaining at the end.

I was just browsing through old posts and came across this one on how much faith to put into the estimator (guessometer is another name, not sure if it has an official name). I know there has not been a post for some time and I guess we have all learned not to rely on this inaccurate estimator. I was wondering though how people go about estimating their driving range and avoiding anxiety. I am in the habit of zeroing the trip meter after every charge (which I always do to 100%) and from experience I know I will get 120km minimum. I find the range averages out, as my driving tends to be mostly repetitive in terms of destinations. I don't look at the estimator, although the number is hard to ignore, being much larger than the trip meter. I have found this approach very workable

Agreed, David, this is a good way to go.
I have always re-set the trip meter on the electric bike after a charge.
With the LEAF, I only do it for longer trips away from home base, when it is interesting to watch how the battery depletes with distance driven.

It certainly is a 'guessometer'. Mine went from a range of 7kms to nothing, and missed 6 through 1 altogether. J ust as well I was only about half a km from home at the time. I always put my trip meter back to 0 after every charge and I always charge to 100%. I got 162 kms out of my last charge but I am only going to get about 150kms this time.

Phoebe, it does this by design. Below 7 it is basically saying "well you asked for it!" and doesn't give you further indication. Below 4 or so it goes into protection mode, capping your max speed to attempt to get you to power.

For the first 8 months our Leaf guess-o-meter usually showed something between 145-165km estimated range after a 15A overnight charge. Generally we get around 125km. Lately it's been acting weird, shows 90km estimate after a full charge which gradually increases as we drive. So we still get our 125km but it takes the guess-o-meter a couple of charges to work it's way back to the normal 145-165km estimate. The car is garaged overnight, so temperatures don't get much below 10C so hard to blame the cold weather. Any body else experiencing these wild swings in range estimate at about the 10,000km mark?

I've had swings like that but always attributed it to the last few drives knocking it out of whack. Like if I spend a few cycles only driving on big hills it will affect it's initial guess. Then as it sees reality not being as bad as it's estimate, it goes up.
When I first got the LEAF a full charge would start with 165KM or so, now it's starts with about 140KM.

Kris, I have the same experience as Jim. When I charge after tootling around town, it reads between 180-190km range, but when I charge after going out on the highway much faster, it reads between 160-170km range.

Post by Jim Hare on Jun 12, 2014 16:08:23 GMT 11
I remember not long after we got the LEAF the range started extending, and at one point a 100% charge would read 195KM, but it quickly learned about my hilly environment and came down. Sounds like Phoebe still gets the high numbers!

Most of my driving is on the flat and through Maitland there's a 40kph speed limit, so that explains my good numbers.

Perhaps we can get "E" plates made up so we can travel economically? But would we then get bullied
Trucks are already limited to 90kmh.
Best is to get an ev truck then won't get bullied and some might be More understanding as one might be carrying a load.
Will be interesting to see what the auspost ev vans get. Also the toll ev trucks.

If you reset the trip meter at the start of a trip, the GOM seems to pay more attention to what is currently happening and less to what has happened in the past. I like going on a trip and putting the destination in the navigator for the homeward leg. You can watch the GOM and the navigators estimates racing towards zero. If the GOM wins, your in trouble. Excitement plus.

Dropped the Leaf back into Javin's for another go at getting the cabin heater fixed. The loaner Micra they kindly provided has a GOM. It changes randomly by 20km just sitting at traffic lights, the Leaf one ain't so bad after all!

I brought a New Leaf It will only go 90 Kms on a full charge Melbourne says I have to except Car stored at Brisbane since May 2012 Sold to me as new May 2014 It is at present with Von Bibra [Gold Coast Dealer ] I want it to do better Kms

Welcome to the forum trevweb. 90kms is low! How many passengers? Is it hilly country? How fast are you going? Are you using Drive or Eco? Are you using climate control? All these factors can reduce your range.

check tyre pressures. imiev original tyres were 145 front 175 rear, not changed to 155 fronts so I might have lost some range due to extra rolling resistance. I run my imiev at 40psi though the door label says 36psi, but interestingly last night I only got 93km on imiev's GOM due to high speed 100kmh travel on the mitchell freeway north bound with a ENE headwind.
If you are heading into a headwind perhaps it is best to use side roads and drop speed to 80kmh max.
