Given the situation, this analysis will be useful for both electric car owners and internal combustion engine vehicle owners. After all, many people thought about (and bought) an electric car in the summer, whereas now, on the contrary, they ponder the advisability of purchasing and/or using an electric vehicle.
Can you save when driving an electric car, and what to do with it when there is no electricity – we provide a specific example. Namely, calculations regarding fuel costs in the case of charging an electric vehicle BYD E2 (the cheapest electric car on the market with a range of 400 km) from a generator.

So, we quote the calculations of the company 4Kolesa, which imports new electric cars from China to Ukraine:
Until recently, such an idea seemed absurd, but not today. Therefore, the 4Kolesa showroom decided to clearly show you that it is not only not absurd but also cost-effective. For example, let’s take the most affordable BYD E2 – by the way, currently, this electric car costs $19,000. For a new car without mileage!
So, let’s calculate. For calculations, we take a 7-kilowatt gasoline generator. On average, it consumes 2.45 liters of gasoline per hour of continuous operation. Let it be 2.5 l/h.
BYD E2 is equipped with a 43.2 kWh battery. That is, it will take about 7.5-8 hours and about 20 liters of fuel to charge it from a generator (converted into hryvnias – 1050 UAH).
Considering the range of 401 km, we have the following:
- 100 km of driving ≈ 262 UAH or 5 (!) liters of A-95 gasoline
