How to calculate the break-even point of electric cars and vehicles as compared to normal diesel or petrol.
The results show that at the moment of purchase, the cost of the electric vehicle is actually higher than the fossil fuel-engine vehicle, but starting in the second year, because of the high cost of fuel, running an electric vehicle costs considerably less.
Break-even point of electric vehicles: the typical curve of the break-even point (bep) graph of electric cars is a step graph, as evidenced by the yellow line in the graph to the left. The cost line is almost horizontal as the amount of electrical energy used is very low. Energy waste has been reduced to a minimum, and the energy used by a set of batteries during an entire day’s work is the equivalent of 1.1 litres of petrol. With this small amount of energy one can transport up to 600 kg for from 70 to 90 km – a cost efficiency result that one could never obtain using a standard petrol-run vehicle. The step upwards in the graph represents the cost of the batteries, which should be replaced every 4 years or so.
For further details about the break-even point (bep) calculation please write us a brief note:
|Energy costs used for the various bep calculations|
|Electricity costs:||0.21 € kWh *|
|Diesel fuel costs:||1.74 € liter *|
(*) Cost sources for the petrol/electricity: Prices applied in the Italian market in April 2010, the vehicle prices do not include VAT.
