Battery range in winter or during very cold periods

Battery range in winter or during very cold periods

Hi everyone,

I am interested in buying a tesla.

Here my question. How strong is the influence of really cold weather in regard to battery range.
I have read, that the "i-MiEV - MITSUBISHI" range decreases during winter days from 150km to less than 50km?

Do you have any experience about the range of the Tesla cars in winter?

You will find a lot of detail in the fora of the Teslamotorsclub:
There is considerable experience around from driving in very cold weather in the US, Canada as well as northern Europe.
The battery of the roadster is climatized, but you will experience still some loss of range due the increased rolling resistance of winter tires and heating. If you use 1 kW to heat the cabin, after 3 hours of driving you will have 3 kWh less in your battery and that corresponds to a reduction in range of about 17 km. If in Summer you have with your driving habits a range of say 340 km, at -10°C that might drop to about 260km. Of course always very much depending on circumstances. If e.g. there is snow, you will drive more slowly and your range increases again, compensating for some of the losses due to heating.

I heard that Tesla owners don't experience that dramatic a range drop because of the climate controlled battery. Three hundred forty to two hundred sixty is a dramatic drop and I don't quite believe that. Then again, I would never drive my expensive Tesla for long when it's wretchedly cold or snowy outside. It's a sports car! If you had a Porsche 911 Turbo, would you drive it in adverse weather conditions? Absolutely not! Sports cars are not even meant to be driven long distances. That's not the point. They are for fun: for soaking up the pure delight of the gut-wrenching seamless acceleration from zero to whatever you feel like in seconds.

What do you want from the Tesla Roadster? This car is very capable, but don't expect it to be able to do anything, because no car can.

Alfred says there that "after three hours of driving...reduction..17km). Not 80km. There is reduction to range, but it is mostly caused by increased rolling resistance and heating, not battery getting weaker.

We drive our Tesla Sport in the mountains of Colorado all year in all weather, through snow, mud, hail, whatever. With good snow tires, it is a great snow car, until the snow is over four inches deep when it becomes a snow plow :-). We see minimal change in range in cold weather. It's just not a concern. And, yes, we would drive a Porsche 911 the same way -- already drive our 1999 BMW m-coupe all year, too.
Then, come summer, we put extreme performance tires on them and go autocrossing. It's a great car. You can drive it anywhere, anytime.
