Linuxluver:.......
We should stop for 15-20 mins every 60-90 mins. At minimum every 2 hours. .....

 

 

Agree. Not only with driving. e.g. - In front of PC to give your eyes a rest or some repetitive tasks you are doing... 5 minute stretch as a minimum.

I worked out how to reset my Kms / kWh meter yesterday. It had been trending up ward steadily.....but that was based on the last 10,000km driven by the car. It had never been reset. It had been steadily climbing from the 6.7km / kWh when I bought it to the 7.0km / kWh it reached on Saturday morning.

This number is a useful metric for your LEAF's range in real life based on your own driving. If resetting it for specific journeys it could also give you a good idea of how much battery you might need to make a specific trip - including real-life feedback on wind, mountains, rain and other actual conditions that affected range on that specific route.  

 

So as of Saturday morning my 7km * the 21 (or 22) available kilowatts gives a nominal range of 147-154km per 100% charge. (2kw of the 24kw capacity are "reserved" so the batteries don't completely drain, which can damage them).

 

But if you drive more efficiently than 7km / kWh then your real range will be higher. Of course conditions don't always allow high efficiency. A steep hill is a steep hill (but at least you get to come down it again....usually).

 

But what is my actual efficiency NOW? I've learned a lot about how to drive in such a way that I blend in with other traffic, yet I don't waste power if I can avoid it.

After resetting the meter I went for a drive from Greenlane (Auckland) to the Mitre 10 on Lunn Ave at Mt Wellington....and back. As urban drives go, it's fairly typical. Up and down a few hills. Stop at some traffic lights. A couple of stop signs. 

I drove 8.8 km. A small, but typical sample and no motorway. At the end of that drive my efficiency was 8.7km / kWh. The actual distance (8.8km), plus the GOM (164km est.) totaled 172.8km potential range for this charge.  

That's pretty good. My LeafSpy showed 22.1kw were available for driving, so 8.7*22.1 = 192.7 km nominal range if I was able to do all of my driving like that. I may even be able to do better. 

So if someone asks you what the range of your LEAF is....the answer is really "How good are you at driving efficiently?" The answer to that (for a 24kw Gen 2 LEAF with 100% capacity battery) will be anywhere from 130km to 200km per charge.......depending on where you go and how you go about making best use of the available power.

I should have said. :-)  

 

You toggle through the pages on the dash display using the two-page icon button (to the right of the steering wheel)...and when you're on the km / kwh display, push the white-dot button. It's to the right of the two-page icon button. It actually resets all the efficiency measures. It's a sort of power-use trip-o-meter.  It also displays average speed since the last time it was reset. You can make that number drop by sitting in the car powered on but not moving. Same goes for the km/kwh. Sitting there powered on and not moving lowers your efficiency as you're using power (headlights, whatever) but not covering any distance.

I'm looking at the 147km drive from Opotiki to Gisborne. That would be a great example of how to use the power trip-o-meter to record the total power used on that journey based on how you drove it. My 30kw LEAF should be able to manage it......but you never know. :-)  It would be good to do it...and record / log the actual outcome for next time and for other drivers thinking of attempting it. Having confidence in the face of the not-done-before, but someone else did it and it was ok, can make the whole thing more fun.

I've been having a play with efficient driving to maximise range.....but not in a way that makes me any slower than the next guy (non-hoons) on the road.

 

Since my last charge on Sunday night, this is what my car looks like Wednesday afternoon.

This included a run from Greenlane, Auckland to Tuakau, south of Pukekohe - and back - along urban streets and secondary highways. Most of it is gently sloping up or down. It's about half urban streets with 50-60kph speed limits and half rural highways with speed limits of 80kph or 100kph. It's pretty hilly in there along Runciman Road and Harrison Road!!! Also lots of 55kph and 35kph tight corners.....which are lovely for wasting your power by making you slow right down, then have to speed up again..... 

 

At the end of the drive my cumulative efficiency was 8.5km / kWh. With 22.1kw available, that's a nominal range of just over 187km.....but the last 10-15 is 'reserved' like the bit below E in a petrol car. You'd only see it if you were almost totally empty.

In the screenshot below, my Actual distance travelled already + GOM (Guess-o-Meter in the dash) remaining range totals at just over 170km....with 80% of the battery already used. That breaks out as 135.4km actual already travelled and 35km remaining on the GOM.......with 20% battery left. So it's real. 

As for driving technique, I've refined my understanding a bit further. Simple thought process: 

1. Accelerate at one dot of power up to your target speed, if no one behind you. On flat ground, this will get you to 75kph or 80kph depending on wind resistance. Maybe less with a head wind (55kph?) maybe more with a tail wind (90kph?) If someone is behind you, use two dots of power up to about 40 kph and then reduce to one dot until the target speed, then just hover around there on the accelerator to maintain the target speed or very slightly over. This is what almost every other car on the road is doing....you're not driving like a nana. 

 

2. Keep the one-dot power level even if going down a slight incline...as this will add momentum 'for free' and let you store energy for the next rise. You may find you have trouble avoiding speeding. This style definitely isn't driving like a Nana....it's just making more efficient use of power.

 

3. As a stop sign, roundabout, tight corner or whatever approaches, try to not use the brake and instead allow time to coast to a lower speed.....and brake to stop if stopping is necessary. Don't be silly. Brake if you have to. :-)  In any case, these wee bits of regen - including braking - are a big help in the long run. 

 

just keep going like this. On a long, steep hill you may have to use 3,4 or 5 or more dots to keep the target speed. The point is to not waste power by *accelerating* on an incline. Use just enough to maintain your speed.....not increase it. You'll find that on the other side of the hill you can ease off the accelerator entirely and regen power back into the battery to regain some of what was lost on the way up.  Again....maintain the target speed to allow for maximum regen. Brake if you have to, that regens a lot of power in a few seconds. You can actually partially regen while applying power by pressing gently on the accelerator and watching the feedback on the power meter. 

 

Driving like this I've found I generally have an efficiency level around 8.5km / kWh.....and maximum range. This will fall if you find yourself needing to do 100kph for a longer period as - short of following a truck - wind resistance at that speed can reduce to your efficiency to around 7km/kWh....or lower depending on the strength of any headwind (whereas tailwinds are great!).  

Most trips in NZ can be done at speeds a bit slower than 100kph ( 110 on the speedo - the LEAF reports high by about 10%)....and you can go further and / or spend less time charging.....

What I noticed was how much speed we waste. Going faster between obstacles and delays doesn't get me there any faster.....it just eats my power and reduces my range. On my drive to / from Tuakau I was constantly catching up to the 'fast guys'......who are ahead of me (didn't have to pass me - I'm not going slow) then they run up the back of a truck, a trailer...or roadworks....or a series of tight corners...or a farmer's tractor....etc...etc....and they don't get there any faster than me, but they waste a lot of petrol.

Range in an electric car is to some extent a function of the attitude of the driver. The car can do 170kms easy.....but can the driver? :-)

If you can find one that is "VAT Qualified", you don't can deduct Vat from a vat inclusive price. (pretty much essential to keep the price reasonable)

 

 

 

Don't forget you need to pay GST on the car at entry, and about $1000 of compliance cost. (Plus shipping, and an agent fee)

 

Takes around two months.

Sounds comprehensive. Who is providing this service? 

 

I'm curious as my own new 2016 30kw LEAF arrives in about 11 days....and will go through all of this. I did it via Autolink in Grey Lynn.

VAT free sounds the way to go.

 

When I brought back my car from when I lived in the uk in 2011; I got a discount for owning more than a year but had to pay GST on the retail price. ie GST on the VAT.....

I had some business to do up north again, so yesterday I headed north in my LEAF around 4am. I wanted to be in Rawene early. 

From Greenlane, I got to Kaiwaka on about 34%. Best ever. My efficient driving practices are paying off. This meant I only had to charge for 15 mins to get to the 80% that would take me to the Northpower substation fast charger in Alexander St in Whangarei. It's about 150m-200m off the highway, so minimises side-trips.

I charged to 80% there to get to Kawakawa (might have made it anyway - GOM said 72km estimated and Kawakawa is 56km - but what the heck). I didn't worry about speed or efficiency as I was going to have breakfast in a cafe in Kawakawa anyway. 

 

While having breakfast, I set the DC fast charger in Kawakawa to "max" and it stopped automatically on 95% about 2 minutes after I returned to the car. That was 37 mins all up. 

I was thinking of trying to do the Rawene leg - return - on one charge, so drove there as efficiently as possible and arrived on 51% (down from 95%)....so I'd used 44% to get there. In theory, this gave me a buffer of 7% on the return leg.

But as it turned out, I parked the car at the Rawene Holiday Camp and started it charging (16amps / blue caravan plug) and went off to do my business. I also wandered around town a wee bit and had fish and chips at the Hokianga Takeaways. (They're pretty good, but Adey's Place at Piha Beach is still King of the Universe where F&Cs are concerned).



After 3 hours I got back to the car around 1pm and opened the doors to let the heat out and put the seat back for a wee nap. One more hour and the LEAF would be on 100% and I was thinking about driving on to Opononi and down SH12 to Dargaville. I've never been that way before, but it's 108km from Rawene to Dargaville, so it looked easily do-able.

Just after 2pm...the sun beating down good and warm....I did go to Opononi. I hadn't been there for over 30 years. It was like a moment out of time in some kind of dream space. The sunlight....the water...the heat....kids playing by the water....on the wharf. I was really glad I'd gone that way. I also had the opportunity to look at a couple of businesses I had been interested in. Well worth the drive there.

Around 3:30pm I headed south from Omapere....and there is a HUGE climb up from the beach to the gap in the hill at the top. This made me think I better drive with a bit of care because I knew there were some hills on the road, but not how high or how many. 

Between Omapere and Waimamaku the highway has some long ups and long downs. The landscape is big and a big dramatic. A really great drive through there. You lose a little power on the ups....and gain back much of it on the downs. 



After Waimamaku, the road begins to climb....and climb...and climb some more.....and as you enter the huge Waipoua Forest (reserve) the highway takes on a slalom quality. Left / right / left / right....so frequently they stop posting speed recommendations. This goes on for about half an hour. Up, up, UP......until you eventually get to the top / crest. By that time my actual distance travelled plus my GOM estimated remaining was collapsing back toward 120km...and I had to make it 115km in total. I wasn't really worried as what goes up must come down and I was sure I'd regain most of that lost range when the road began to descend. Plus the braking regen....which seems to be the best. 

Meanwhile, up there I stopped and went along the short track to see "Tane Mahuta", the huge kauri tree. It is certainly is huge! If you've never been up there......go. Just to see it. 

The road absolutely, definitely did descend......another it was another slalom. Left / right / left / right......lucky to hit 50kph...and almost all downhill. The low speed, declination and braking regen were doing wonders and I did about 12km for 1% of battery.....and the normal value there would be 1.6km.....so if all driving was like that, the LEAF would have almost 1,000km range per charge. :-)   

Eventually I got down to the flat....and had loads of battery to spare for the remaining distance, but I didn't want to spend much time charging in Dargaville, so I took it easy. The actual distance plus estimated had recovered to 152km....a bit lower than at the start of the trip, but a lot more than 115km actually traveled on that leg. 

The weather west of Dargaville looked like absolute rubbish, so I charged up to 90% to get to Kaiwaka (took 30 mins while I had a walk around......shaking off the effects of what felt like almost an hour of slalom driving).

On the road to Kaiwaka, just west of Ruawai, the skies opened up and the rain was extremely heavy. Wipers on super fast...and occasionally planing through water that ponded on slight depressions in the quarter chip road surface in a few corners. That was exciting.....not.

 

I got to Kaiwaka on about 40% and charged up to about 90%. That took about 26 mins. The sun was just going down. The western wall of the Kaiwaka library is covered in wooden tiles painted darker colours. The air was cooling down, but the wall was lovely and warm. I wondered if maybe the wall was heated from inside as there is a sort of bum-bar across part of it. Whatever....it was a great, warm place to stand and watch the sun get lower and lower......and lower. It was about 6:30pm and everything in close walking distance to the Kaiwaka charger was closed. There's a pub further up, but I couldn't be bothered. I wasn't going to be there long.

 

On 90% I stopped the charger and headed home to Greenlane. I know this stretch well now and abandoned any idea of driving efficiently. No one would ever speed, of course. It's illegal. I got home not long after 8pm.

That drive, in total is about 560km. Did it in a day....with about 6 hours spent doing things other than driving....which were the whole point of going.  

I really enjoy the tiki-tour side of driving the LEAF. You have to stop....and I get to see things I've never stopped to see before.  I was always in too much of a hurry. :-)

I do include the battery percentages and charging times to demonstrate the trips are do-able...and capacity usually isn't an issue....and charging time is usually about the same as stop for a coffee and a toilet break.
