Regarding temp- yes, 60 is lower than what I and every other person I’ve ever met sets thermostat in winter. No, didn’t want to wear shorts. Is that shorts weather where you live really? Maybe if I’m outside being active but not just sitting in a car.
Re: conditions being “bad” because rain and a little cool outside. I’m not sure but I feel like this might be about average for me and maybe better than average for conditions. It’s hot and humid all summer and will be using AC. Winter gets much colder. Maybe AC doesn’t use much power comparatively, I will find out. This is new to me as I said.
Re: keeping radio off and heated seats / steering. Sorry, again, new to me as I said so wasn’t sure of exact power draw of these items. It seemed to me in my experiments so far that seat heat was in fact noticeable w regard to range. Must have been mistaken. But like I said, my other reason for keeping that heat off is to make it even for all occupants so I’m not warm while people in back are feeling cold. Radio was on most of trip, turned it off a couple times. Wasn’t sure of power draw of the equipment at the time.
Re: 9% being a big cushion. Not to me. Not when car becomes a brick when you run out. Not going to hitch hike up the road to a gas station.
As I’ve stated before, I feel it necessary to mention that we just love this car. Range is totally fine for us. Just a bit less than I expected at higher speeds and using heat.
Also- thank you for all of the comments and helpful suggestions. I am not an enthusiast, just a car owner. I don’t think I have any more need for anything here and don’t particularly enjoy the conversation tone so this is goodbye.
I did a bit of a road test yesterday and hit 4.5 miles per kwh. Weather was mostly good. some rain in the morning. 75% of trip down with Cruise control set to 65 mph (or about 67 on the analog speedometer )DougWantsALeaf wrote:I know this makes me sound like a grandpa, but 55 is about as fast as you want to drive the leaf. On a temperate day at 55if carefully driven, no wind, no havoc, high psi, you can do 5 miles per kWh (13 leaf). The 18 should be able to do a bit better. 37kWh *5 = 185 miles in perfect conditions. But 65 or 75 is out of the question.
It's true that you made it clear that you only did 75MPH for 25% of the time. It's also true, though, that if you had done 65MPH that 9% cushion would have been more like 15%. It was the combination of pushing the car to a point where energy consumption was high, and complaining that 9% left wasn't enough, that led to the negative response here. It also didn't help that you left the seat and wheel heaters off while complaining about the car being cold. (Nissan needs to make it clear in their literature that the seat and wheel heaters don't cost range.) It was probably too negative, though, and at least some of us will try to be nicer in the future.People keep bringing up the 75 mph as if that was the speed of this trip.

This is the sort of prose that gets you negative responses. In my case, if I used only seat heat and low cabin heat, my feet would freeze - I have bad circulation. You raise an interesting question, though: is it selfish to run your seat heater in an EV if someone in the back seat has none? I guess I'd respond with "Is it wise for the driver of an EV to lower his or her body temperature in order to not seem a "dick"? Cold is sort of like weak beer: it slows your responses down without it being obvious enough for you to notice.Lastly, would you really do that? Run an uncomfortable cabin temp for other passengers while you’re nice and warm using seat heat that they don’t have available to them? Seems like a dick move to me.
Mixing up kw and kWh is very common when ICE folks discuss EVs. It is important to keep them straight. It causes major confusion when they're mixed up. Its not always clear from context. The LEAFs battery has a capacity of 40kwh while chademo has a max charge rate around 45kw. Since the values are close, if context is left out major confusion results. Another example, Tesla Model S can have a battery capacity of 100 kWh while superchargers charge at a rate of something over 100 kw.SageBrush wrote:I'm sorry you do not understand, but I hope OP can: using correct units aids in communication. Not only does it prevent misunderstandings, it facilitates understanding. If I do not have to waste time and effort parsing a poorly communicated question I (and I presume others) are more likely to spend time and effort trying to give an informative answer.DuncanCunningham wrote: Don't worry about the two pedantic fellows in here harping about about your terminology and correcting you all the time.. this is their hobby and lose sleep at night about their clocks being 1 min off. the rest of the things they share and help you with you are totally worth it though. loves to the OCDs.
OP can view an effort to communicate clearly as self interest.
The energy requirement per distance needed to overcome air friction as speed changes is indeed a quadratic relationship but the tyres stay about the same and the drive train is linear. At the speeds we are usually discussing (60 - 80 mph) a graph of Wh/mile Vs speed has a somewhat surprisingly quite shallow curve. If you just look at 5 mph differences and are not paying attention you might wrongly state that the change is linear.dm33 wrote: directly proportional to speed. If you drive twice the speed to cover the same distance, it will take twice the power. Physics. Works the same way in an ICE.
