Electric car: consumption and costs


Electric car: how much me costs? Apart from the purchase, but prices are leveling up, the electric car undoubtedly has economic advantages over a traditional car. The most obvious is in the consumption. Then there are the costs management, road tax and maintenance, which are facilitated and much lower than those of a thermal engine vehicle.

The third advantage of aelectric car, and throw it away, is the freedom of movement in the city and historic centers, combined with the awareness of contributing to the reduction of pollution. Forget long journeys, but for moving around the city and surroundings this solution can already be a bargain.

Electric car: consumption

The Consumer Orientation Defense Association (Adoc) has calculated that with an electric car you can spend only 3 euros to travel 160 km, which is around the maximum range of a good electric vehicle. To verify this data, we need to know how much we pay for electricity and how much autonomy the battery of our electric car offers us.

Let's put aside what the car manufacturers say and count the servant. Energy should be measured in Joules (J) but since it is electricity we reason in kilowatt hours (kWh), which makes everything easier because it is on the kWh consumed that the various suppliers charge us for 'light'. With particular mechanisms, at their fixed costs and taxes.

The euro / kWh price depends on the supply contract and the time at which electricity is taken. In the domestic two-rate tariff, the consumption bands F2-F3 (evening and holidays) are cheaper than the F1 band (daytime). In business users, however, the opposite occurs: electricity costs less during the day and more in the evening, on Saturdays and Sundays. Recharging the batteries of the electric car is convenient at home in the evening and on holidays, in the office during the day.

How much energy does the battery hold and for how many kilometers? If we imagine a car battery capable of accumulating 24 kWh to give a range of 160 km, the cost per kilometer will be: 24: 160 = 0.15 kWh / km. At this point it is sufficient to multiply the two values ​​- € / kWh x kWh / km - to obtain the cost per kilometer in euros.

Certainly the real data counts - in terms of autonomy those declared by the houses are not yet very precise - and other factors also count. Some electric cars for example, they recover energy from braking and this increases the range by lowering the cost € / km. Overall, it can be said that the value calculated by Adoc (3 euros per 160 km) is a credible average and in any case the cost-consumption of an electric car recharged in an intelligent way is really low.

Electric car: maintenance costs

Even in terms of engine maintenance,electric car it is more economical than petrol or diesel. There are fewer components and the wear is less. Certainly the batteries must be checked and at some point even replaced, but all in all the expense of the mechanic is contained.

As regards the stamp duty, in Italy it was decided to encourage the spread of electric cars by zeroing the government tax for a period that varies from region to region. On the insurance front, more and more companies are equipping themselves with ad hoc products for e-car and policy prices are lower than those applied to traditional cars.

Electric car: private and collective benefits

Being able to move around the city without restrictions is a non-negligible advantage, even an economic one if you consider the exemption from tolls. As for the environment, well, certainly the electric cars they make a great contribution to improving air quality. E-cars also pollute a bit, God forbid, but they are more 'sustainable'.

An interesting debate from the environmental point of view is that of problem shifting of production. Build electric cars in energy-intensive factories, burning oil would only move the problem without solving it. But if the manufacturers of e-car invest in making the entire production chain energy sustainable by using only renewable energy - as BMW is doing for example for the BMW i3 model in the Leipzig factory - then things change.
