-25 celcius has eaten 66% of my range

Model S 70D

So it is -25 celcius (-35 with wind chill). I started out with a cold battery from my garage with 337km rated range. I drove local and highway during the day and the actual range was only 115km. This equates to a range loss of 66%. Driving style was generally slow acceleration due to snow and slippery conditions.

Wow. That's cold. Instant booger freeze temperatures there.

Says 101.8km since last charge???

 

[cinergi]

snow on road = major range loss
Pic shows low tire pressures = range loss

 

[vchadha]

101.8km is what i drove. When i arrived to supercharge i had 30km rated range left which equates to about 10km.

 

[vchadha]

The tire pressure were only slightly off.

I drove from Quebec City to Montreal Friday morning at 105 km/hr with average conditions of -22C and 8 km/hr headwinds. It took 396 rated km for 260 actual km, so the loss was just a third. The roads were dry, though, and nothing like today's swirling winds. The car was also in a 15C garage where I overinflated the tires to 50 psi.

Sorry about your experience today. We could use more than 1.5 Supercharger sites in Quebec to alleviate range loss due to severe weather. If you have concerns about specific trips, evtripplanner's range estimates are much more accurate the car's navigation system in the Winter.

This cold weather really cuts into the battery mileage. Here, it was -20 overnight. I still had the regen limiter line after charging the car for 5 hours and then driving for an hour.
I lost about 50% of my range.

 

[vchadha]

Yes, on a long trip with highway driving it makes sense that you experienced a range loss of 35%. Due to stopping and starting i lost 65%.

 

[vchadha]

Yes, i think it is important for everyone to know the effect on range with such cold weather to help plan better

Futures buyers should be aware of that. Even with a warm car, driving at 100km/h at 0c on the highway, I drove 55km instead of the 100km indicated. This is far from the 12% lost Tesla's salesman told me!

Thanks to regen, stop 'n go doesn't usually eat into EV range as much a highway driving, but I guess your regen was limited due to cold.

Try to finish charging right before you leave as charging warms the battery. Also if you are connected to power, prewarm the interior before you leave also to help reduce consumption on the road.

That is pretty cold, about -12 F. In the depths of winter we often get -20 to -25 F here. However, I don't believe windchill has any effect on the car, unless it is a headwind you are driving into.

Cold weather really is a killer. If you think it's bad in a Tesla, try it in a Leaf. You're lucky to make it out of the driveway (slight exaggeration to make a point).

Wait... you have electricity in Canada?!

 

[TexasEV]

Snow and wind will affect gas mileage also. By the way, a car doesn't feel wind chill.

 

[Canuck]

Yes, igloos have come a long way.

Once the battery is warm you lose 35 to 40% range at -25 celcius temperature

Must be additional factors such as heavy snow, heavy wind or rain for such a bad efficiency to occur. I have driven my P85D just over 300km without issues in those temperatures at over 100kph average speed. Not hypermiling either. Of course using range mode.

I have _never_ seen anywhere close to 50% reduction in range even en -20c temps on the highway. Worst I've had was maybe a 33% reduction in heavy snow, winds and cold temps.

city-driving with stop and go traffic is another story. Easily more than double the energy used per km. But then I rarely do more than 200km of city-driving
