I use 1% of battery to precondition my Tesla to heat the cabin and battery on cold days in Winter I (this also maximises regenerative braking performance - I gained 2% battery driving down from the Blue Mountains a few weeks ago.

I also used to preheat my ICE car on cold winter mornings.

Here’s How Norway Defied Nature And Widely Adopted EVs

Norwegians live in one of the coldest, most mountainous countries yet EVs are outselling ICE vehicles there.

Norway is one of the world’s coldest countries and this makes it one of the least suitable for battery electric vehicles. However, in spite of this, the affluent northern European has beaten the odds to a point today when EVs are outselling ICE passenger vehicles. And your friends might give you strange looks if you buy a new ICE car today and not go electric like most of them.

It’s all thanks to the country’s excellent charging network, that enables EV drivers to drive to most points of interest in the country. Norway is not only cold, but also mountainous, there are places in the north of the country where temperatures are low throughout the year and the more polar part is mostly uninhabited territory, not the place to suffer from range anxiety or run out of juice...

According to electromaps.com, there are currently 2,744 charging stations that have a total of 7,233 separate connectors in Norway. That puts it above Portugal and below Switzerland and way below the Netherlands where there are a total of 58,380 stations with a total of 110,834 connectors, according to the same site.

But Norway is nowhere near as populous as the Netherlands (5.4 million versus 17.4 million) and it has another area where it is superior to pretty much any other country: the source of the electricity, 98 percent of which comes from renewable sources and that puts it in a very unique position.

Then there are also the generous government incentives and Norwegians desire to be ahead of the curve that have surely contributed https://insideevs.com/news/564872/norway-evs-charging-infrastructure-explained/

So why is Norway so far ahead in terms of electric vehicle adoption? It’s a combination of policy measures and the country’s wealth (ironically obtained from its vast oil reserves). Norway imposes hefty vehicle import duties and car registration taxes, making cars significantly more expensive than in most other countries. By waiving these duties for electric vehicles, Norway is effectively subsidizing EV purchases at a level that other countries couldn’t afford. Add free parking to the mix and going electric suddenly looks like a tempting proposition.

What makes Norway’s electric vehicle boom even more notable, is the fact that the country’s electricity comes almost exclusively from hydropower. That way driving an electric car in Norway is even cleaner than it is in countries heavily reliant on coal.
