Do Road Conditions Reduce Tesla Model S Range More Than Temperature – Video


Tesla Model S Energy Consumption

Tesla Model S Energy Consumption

In this video, Bjorn Nyland attempts to show how road conditions affect range more so than outside temperature.

Nyland says that rain, snow, slush, etc. increase energy consumption in the Tesla Model S rather significantly, but temperature variations have less of an impact on how far the Model S can go.

Video description:

“I explain how Tesla Model S uses the excessive heat to warm up the battery and inside the car. Because of this, outside temperature barely reduces the range. It’s mainly reduced by rain and snow/slush.”

I think it’s fair to say that even early built Model S last a while πŸ˜€

Heating the cabin aside, pushing through colder/denser air uses more energy. The speed the car is travelling will also determine how much the temp has an effect. The only way to truly test this is to drive over the same flat patch of road in several different conditions/speeds and note the kW being used. Tesla also has dials on their website where you can play with the speeds and temps.

in the upper midwest, air densities can vary by about 15% over the range of temperatures that you can typically expect over the course of a year, so i understand that part of it. what i don’t understand is how speed affects the manner in which temperature affects energy consumption. there isn’t really a “wind chill” effect with respect to a car.

Wind resistance increases as the cube of the speed, if I recall correctly. It’s said the average car spends about half its energy fighting wind resistance at 55 MPH; obviously this percentage increases at even higher speeds.

If the air is denser, offering higher wind resistance, then an increase in speed will affect energy consumption (and therefore range) even more.

I wonder how much the presence of rain in the air affects things? Seems like the mass of raindrops hitting the car at any time must be tiny, but common sense says there will be a cumulative effect over time. However, that effect may be insignificant. If the pavement is wet, my guess is that the tires having to continually push water out of the way would have more effect on energy consumption.

As someone noted, these conditions affect the energy consumption of all cars, not just EVs; a gasmobile’s MPG will go down in adverse weather conditions, too.

Thanks for explaining. I didn’t go into detail in my post.

Sidenote, at one time I started collecting data on my Volt when I first got it, and even started building a graph. (But then I got lazy)

“It’s mainly reduced by rain and snow/slush.”
As any other vehicle.

Can’t wait for Bjorn to take delivery of the model X and flood us with his experiences πŸ™‚

Yeah, I too, am eagerly awaiting that. πŸ™‚

if you look at the instrument panel display, the outside temperature was 9 celcius; that’s nearly 50 fahrenheit. at that temperature you won’t see much temperature dependent range loss. under those conditions, recovered heat from the battery would likely be adequate to heat the cabin. where you are more likely to see significant range loss is when you are at -10C/14F. under those conditions, you actually have to drive the heating system.
