As of October 2025, the Ukrainian electric car fleet will number 193,500 vehicles, of which 98% are passenger cars, and the rest are commercial models of the LCV category, according to the Institute for Automotive Market Research. Despite the growing popularity of electric cars, their electricity consumption is only about 0.6% of the total annual consumption in Ukraine, which does not pose a threat to the power system.

Analysts note that even if the number of electric cars doubles or triples to 0.6 million units, their consumption will increase to about 1.9%, which is also not critical for the stability of the power system.

The average electricity consumption of a passenger electric car in Ukraine is 16.8 kWh per 100 km in summer and 21.8 kWh in winter. At the same time, the typical annual mileage for a Ukrainian BEV reaches 12,800 km, which allows us to calculate the daily and monthly electricity demand of the fleet.

According to expert estimates, the average daily electricity consumption by electric vehicles is 1,141 MWh in summer and 1,480 MWh in winter, and the average monthly consumption is 34.7 GWh and 45.0 GWh, respectively. Thus, the annual demand of the Ukrainian fleet in the "on-the-go" format, taking into account seasonality, is 468 GWh.

However, the real impact on the power system takes into account additional losses: the efficiency of inverters and chargers, the operation of battery cooling and heating systems. The average value of such losses is 10–15%, and applying a coefficient of 12% gives the actual demand of Ukrainian electric vehicles for energy from the grid of about 524 GWh per year.

For comparison, this consumption is equivalent to the total electricity consumption of all of Ukraine for 1.5 winter days or 1.5–2 summer days. Thus, the current and projected electric vehicle fleet does not create a critical load on the country's power system, and its impact remains controlled and predictable.
