Hoser,
I have issues with the current range of electric vehicles. When they can travel up to a thousand km on one charge in 40 below zero temperatures I might consider one.
Traveling up 1,000 kilometers (620 miles) is not necessary for any vehicle. My Ford only has a 220 mile range and many cars get about 400 if they get 25 mpg. A Toyota Prius has a 500 mile range.
As for temperatures, there is solid state battery technology (In the first stages of research) that can currently operate in minus 20 Celsius degree (-4 degrees Fahrenheit). With all the leaps and bounds that battery technology is going through it's simply a matter of time. Say 5 years?
