How to determine the fuel consumption of an electric car
There are various units of measurement as well as certain technical data that may influence energy consumption of an electric vehicle. That's what we'll be looking at in this article.
Tools for measuring the fuel consumption of an electric car
It is possible to measure the average fuel consumption of an electric vehicle. The unit of measurement is MPGe or Miles Per Gallon equivalentwhich measures the average distance travelled per unit of energy consumed.
According to theEPA (US Environmental Protection Agency), in terms of energy value, the American agency estimated that the consumption of one gallon of petrol (3.8 litres) represented a electricity consumption equivalent to 33.7 kWh.
The MPGe rating is therefore an effective tool for comparing the fuel consumption of an electric car with that of a conventional car. thermal vehicle. At the same time, this unit of measurement makes it possible to compare the average energy consumption of different electric car models, with the aim of identifying the most energy-efficient electric models.
Another possible way of measuring the energy consumption of an electric vehicle is to use the kilowatt-hour (kWh) unit to determine the number of kWh consumed per 100 km/h.
Characteristics that influence the fuel consumption of an electric car
The fuel consumption of an electric car will be strongly influenced by a number of factors, including the size and power of its battery. The specific characteristics of the electric battery will therefore be a factor to take into account if you wish to acquire an electric vehicle with energy consumption reasonable.

What's more, the size of the electric car itself is generally an indication of whether it consumes more or less energy. In fact, as a general rule, the largest electric cars are the most energy-efficient. compact will also be the most fuel-efficient, compared to larger models such as the Electric SUVs.
So, logically, a electric city car such as the Fiat 500e will be far less energy-intensive than an electric SUV such as an Mercedes EQCfor example. If we compare the energy consumption of the two electric cars, we can see that the Fiat 500e will have a fuel consumption of 13.2 kWh/100 km for its 23.8 kWh battery, while a Mercedes EQC will consume 22.2 kWh/100 km according to the WLTP standard.
If you are planning to buy an electric car, but you have a fairly limited budgetSo it may be a good idea to opt for a relatively compact electric car. In fact, a smaller electric vehicle will tend to consume lessas well as representing a lower initial investment.

What's more, the energy consumption of an electric car also depends on other factors specific to each electric model, but also on the type of travel carried out.
Electric cars tend to consume more energy on the motorwayThis increase is mainly due to the speed reached by the electric vehicle. So, if the majority of your journeys involve long-distance routesIn this case, you'll tend to use less energy. greaterwhich will increase your electricity costs.
In addition, the type of driving style adopted is one of the factors influencing the energy consumption of an electric vehicle.
Indeed, driving more slowly and adapt your behaviour flexible allows reduce the energy consumed by the vehicle. It is also relevant to develop aeco-driving which will help you to reduce your energy consumption during your journeys.
