(2) Most importantly, the emissions of electric vehicles will (likely) go down during their lifetime, while ICE cars’ emissions will remain constant. Electric cars have two distinct official ways of measuring how far they will go on a single charge. 5. The new test that is now used to determine a car’s range is called WLTP (Worldwide Harmonised Light … Compared with a petrol or diesel car emitting 121g/km CO2 -the average for new cars in 2017, which includes the BMW 318i - an electric car saves its owner between £165 and £205 in its first year, and then another £140 per year going forwards.

As more car buyers take the plunge into owning an electric vehicle (EV), … If in fact the 40 g CO2e / km are not included, then diesel vehicles would average between 190-200 g CO2e per km, making the comparison to EVs slightly more favorable to electric vehicles. the cost per mile). Analysis by the Energy Supply Association of Australia (ESAA) found that an equivalent litre of electricity, or e-litre, could cost from 37 cents off-peak up to 62 cents with peak prices. Here, we’ll run you through how to calculate both, and the different factors that can affect them. In simple terms, the maths is: Size of battery (kWh) x Electricity cost of your supplier (pence per kilowatt hour) = Cost to charge an electric car from absolutely empty to full. So what’s a kilowatt hour or shall we ask Watts a Kilowatt hour? Electric car range: cars with the longest range. After getting a boost to its battery for 2017, this electrified version of the Ford Focus sports a 33.5 kWh pack. When it comes to the running costs of electric cars, there are two main figures: the cost of charging, and how far that charge will get you (i.e.
