EV consumption in kWh per 100 km (consumo del coche eléctrico)
The energy an electric car uses to travel 100 km, expressed in kWh. It is the equivalent of litres per 100 km in a petrol or diesel car and is used to work out range and the cost of each journey.
What kWh/100 km means
Consumption in kWh/100 km tells you how much energy an electric car needs to cover 100 kilometres. In Europe it replaces the litres per 100 km of a petrol (gas) or diesel car; Americans more often see miles per kWh. It is the basis for knowing what driving will cost you.
How much an electric car uses
An average electric car uses 16 to 18 kWh per 100 km. Add around 10 % for charging losses, the energy lost in the charger and cable. For 15,000 km a year that is about 2,400 to 2,550 kWh, or 200 to 210 kWh a month.

How to pay the least
Charging at home overnight, in the off-peak (valle) period of the 2.0TD tariff, is the cheapest way. With an off-peak tariff the monthly cost is around 20 to 30 euros; with a normal flat tariff, 50 to 60 euros. With solar panels you can also charge by day with your own energy.
