How much does it cost to charge up an electric car?

Have you ever wondered how much it costs to charge up an electric car? Me too. But, of course, somebody in the Internet machine has done that calculation for us (in this case CompareTheMarket).
Now obviously, the cost to charge up a vehicle will depend on the vehicle (i.e. its battery size) and on the cost of electricity in the area the car is being changed in. CompareTheMarket has given us estimates based on a variety of countries with a large variety of electricity costs, ranging from Chile (with a price per kWh of US$0.07) to Denmark (US$0.34 per kWh). Canada and the USA are somewhere in between at US$0.11 and US$0.13 respectively (costs may vary a bit within different states or provinces).
The cost to fully charge a Tesla Model S - which conveniently has a 100 kWh battery, sufficient to provide 259 miles, or about 417 km, of worry-free driving) - is therefore about US$11 in Canada and US$13 in the USA. That stacks up pretty nicely against filling up a car with enough gas to cover 259 miles (417 km) although, again, direct comparisons would require a knowledge of a particular car's fuel efficiency, the cost of gas in a particular state or province, etc. It's enough to provide a rough guide, though, and it certainly looks attractive.
