The China Mail - Arctic cold 'no sweat' for electric cars in Norway

Tesla owner Philip Benassi has experienced it on cold winter days, but like other Norwegians, he has learned to cope with it.

With temperatures often falling below zero, rugged terrain and long stretches of remote roads, Norway may not seem like the most ideal place to drive an electric car, whose battery dies faster in cold weather.

Yet the country is the undisputed world champion when it comes to the zero-emission vehicles.

A record four out of five new autos sold in Norway last year were electric, in a major oil-producing country that aims to end the sale of new fossil fuel cars by 2025 -- a decade ahead of the European Union's planned ban.

Benassi took the plunge in 2018.

In his gleaming white Tesla S, the 38-year-old salesman for a cosmetics company clocks between 20,000 and 25,000 kilometres (12,400 and 15,500 miles) a year.

Like most new electric vehicle owners, he had moments of panic in the beginning when he saw the battery gauge drop quickly, with the prospect of it falling to zero on a deserted country road.

"I didn't know the car well enough. But after all these years, I have a pretty good idea of how many kilowatts it needs and I know that it varies a lot depending on whether the car has spent the night outdoors or in a garage," he told AFP.

The car uses much more battery when it is parked outside in temperatures that can reach minus 15 degrees Celsius (five degrees Fahrenheit), Benassi said.

"It takes quite a while for it to go back to normal consumption," he added.

In the cold season, how much range electric cars lose depends on the model and how low the temperature gets.

"But the following rules of thumb apply: a frost of around minus 10C will reduce the operating range by around a third compared to summer weather, and a severe one (minus 20C or more) by up to half," said Finnish consultant Vesa Linja-aho.

"By storing the car in a warm garage, this phenomenon can be mitigated somewhat," he added.

- Charging stations -

Drivers must plan their routes before long journeys, but car applications and Norway's vast network of more than 5,600 fast and superfast charging stations help make the process easier.

Electric cars accounted for 54 percent of new car registrations last year in Finnmark, Norway's northernmost region in the Arctic where the mercury has at times fallen to minus 51C -- a sign that the cold problem is not insurmountable.

Other Nordic countries that regularly experience chilly temperatures, such as Iceland and Sweden, also top world rankings for electric vehicles.

"Now more and more new electric cars have systems for pre-heating the batteries, which is very smart because you get more range and because if your car is heated before you charge, it will also charge faster," said Christina Bu, head of the Norwegian Electric Vehicle Association.

Electric car owners are not the only ones who have to worry about the cold.

"Actually, if it's very, very cold -- freezing temperatures -- sometimes diesel engine cars can't start and an electric car starts," she said.

- 'Everyone can do it' -

Norwegians are clearly sold: more than 20 percent of cars on Norway's roads are now electric -- and green, with the electricity they consume generated almost exclusively by hydro power.

Norway's longstanding policy of tax rebates for electric cars has facilitated the transition, although the government has begun to roll back some of the incentives to make up for a budget shortfall estimated at nearly 40 billion kroner ($4 billion) last year.

There is "a simple answer to why we have this success in Norway and that's green taxes", Bu said.

"We tax what we don't want, namely fossil fuel cars, and we promote what we do want, electric cars. It's as simple as that," she said.

"If Norway can do this, everyone else can do it as well."
