74 miles on a single charge?

Fri Mar 22, 2013 1:56 am

Hello everyone,

I already asked the following question in the Newbies section already, and there were no replies yet, I figured probably because the question was buried deeply in the rental car thread. So I hope it's ok that I post it here again, as it is the "range" subforum - otherwise, dear moderator, just delete this post. :)



It's 74 miles from the dealership in Massachusetts where I will rent the Leaf to my final destination. 50 miles of that is highway - the rest rural roads with maybe 35mph of a speed limit - will I be able to make it on a full charge, or do I have to stop along the way and top up? The dealership said the Nissan Leaf will be fully charged at pickup, and there also are no plans to drive around further for a while once arriving at the final destination, so it's okay to arrive with a nearly empty battery.

I read a lot about range, like Paul Scott gets 100 miles on a full charge, and there is the range chart here on the forum with also seems to indicate that the 74 miles are doable. Then again, there is this thread here "The Dealer told me not to buy a Leaf", and there people are saying it might even not be possible to do 80 miles in a day, even with recharging.

In my case, it will be June, so it's not going to be freezing. Still, maybe light AC use will be nice (which takes some extra energy, it can also be turned off for a while), and New England is a little hilly, which could cost some range, and the car will be loaded with 2 passengers, still eco mode can be permanently switched on - will 74 miles on a single full charge be possible?

Thanks for any replies,
best regards,

It'll be a piece of cake as long as you go no faster than 65mph on the freeway.

Correct. I'd be conservative with freeway speed, and put the A/C to a fairly high setting, and not something like 68 F. That should help dehumidify the cabin, and keep it pleasant without consuming too much energy. Please have a look at Tony's latest range test. It's been demonstrated that the LEAF can travel more than 80 miles at a steady speed of 65 mph indicated on the dash. Please keep in mind that there will be numerous warning chimes as you slide below the very low battery warning. It can be a bit unnerving for a new owner. Please watch the state of charge, which should be indicated as a percentage gauge on the dash now. You might want to try to get about 0.9 miles per percentage point. Also, ask the dealer to help reset the energy economy gauge before you head home. Try to keep it above 4 miles/kWh.

I recently drove 63 miles one day and the guess-o-meter still showed 31 miles remaining. Granted I probably hadn't exceeded 50 mph that day but I would think I could have easily gone another 11 miles and then some. Our Leaf is almost a year old and has 8,000 miles.

I would actually chime in and say this will be cutting it close. But I will agree it should be doable. I would try to stay under 65 on the highway. I'm not sure what kind of highway it is, but maybe if you can find a big truck, bus, or something moving slow then just get behind it and stay behind it. Not only will it help remind you to keep the speed down, but others will blame the slowness on the large vehicle and not you so you don't have to be embarrassed going slow.

Also if you are "renting" this Leaf, how do you plan to charge it? If you are going to use the 120V cord, it is worth mentioning that you are going to arrive at your home with pretty much a fully drained car. A full charge with the 120V cord will probably take nearly an entire day, probably close to 20 hours.

Also, you want to confirm that the dealer will be charging to 100% and not 80%. The dealers don't always seem to know how to charge to 100%.

I don't know what the weather is like in Massachusetts right now, but we have a descent amount of snow in NY, and I would be a little nervous to drive 74 miles on a charge in cold and/or snowy weather. Keep in mind that cold weather impacts range, especially when you use the heater of if you're dealing with snow (increased rolling resistance). I would suggest not using the heater on your trip if at all possible. I keep the air circulation on outside air instead of re-circulation because, in my experience, the windows don't fog up as easily, allowing me to skip the defroster (which works with the heater and will reduce your range). Drive in ECO mode, accelerate slowly, coast to a stop whenever possible, and keep your speed down if it's safe. Also, don't be afraid to put the car in neutral to turn off the regenerative breaking to maximize your coasting distance, or to switch to D to reduce the regenerative breaking to coast to a stop over long distances (if safe). Lastly, I would check out PlugShare to see what public and private charge stations are available near your route because you may need them.

I just plugged 74 miles into the LEAF Energy App, and at 32 F (the current temp. in Boston, MA, which may or may not be accurate for your location) it tells me that you would need to average 3.9 miles/kwh to complete your trip on one charge. I honestly don't see you getting 4 miles/kwh if it's 32 F where you live, and certainly don't see you getting that if it's snowing or you use the heater. Maybe I'm being pessimistic, but I do live in a cold climate and I notice that the people who say it's doable all live in much warmer climates. FYI, at 70 F the LEAF Energy App says you would only need to average 3.5 miles/kwh, which I think would be easy on a 70 F day. Does anyone with experience in a cold climate disagree with me?

Mr. Scott is the rare exception of folks suggesting the car will go 100 miles in the mass USA consumer's hands. I actually seriously doubt that he regularly drives 100 miles per charge... he merely presumes that it will based on his extreme driving techniques, and maybe it will. The LEAF just doesn't normally go 100 miles, and it does a disservice to the LEAF to tell consumers that it does. You'll note that Nissan has long since stopped advertising 100 miles of range.

That doesn't mean you can't drive it 151 miles, like LEAFfan did, or 100 miles like these 44 souls did, including me. Go read the linked thread to see what folks have to do to ACTUALLY drive 100 miles (you'll note Mr. Scott is NOT on that list).

With summer time with a new car, heater off, moderate steady speed at 65mph with no elevation gain overall (going up and down rolling hills will only marginally affect range, provided the end point is not higher that the start), the car will go about 81 miles, plus or minus a few. You want to go 74, which is ENTIRELY doable, but yes, you will see Low Battery Warning at 17% and also likely get close to Very Low Battery Warning at 8%. As the Range Chart shows, at 65 mph, you have about 4 miles remaining before Turtle mode.

If you can remain within the prescribed parameters, you'll make it. If you run the air conditioning, there will obviously be a closer margin of error. If you are not driving at a steady speed, you need to have 4 miles per kWh or better economy.

As the car ages, or if the battery is cold, its capacity will be diminished and this trip won't be possible at the same speeds. Snow and standing rain on the roadway will also diminish range.

this ought to be easy, as it is in june, unless it is raining. dont pull a broder.
check that u r at 100% or charge up.
weather counts in efficiency. rain or snow are bummers.
you are a rookie, so watch the bubbles and dont ever see 3 for more than 5-10 seconds. just slow down and ride the wave. you dont need to push, it will accelerate and build momentum when you start from stops.
watch your bars to see your power usage.
you have 12 bars, if you get 6 miles a bar on the first few, you have developed a good pace and you will make it.
if not, adjust your driving style--just go slower. turn off the heater, or in this case, the AC, which is far less a factor than heating, but still a factor.
there are about 10-15 miles you cant see in bars--so cut ur speed after you start getting warnings.
folks will fill in on that number, i am sure, to tell you precisely what distance is left at Low and Very Low Battery warning.
