The development of electro-mobility in Poland is one of the inevitable processes certainly awaiting the Polish automotive industry. It is expected that in the next few years, electric cars will become a viable alternative to petrol cars. Available reports an studies indicate clearly that the costs of purchasing a new electric vehicle are much higher than a vehicle powered with conventional fuel. Therefore, the expectations of the customers themselves regarding the costs of the operation of such a vehicle, including the prices of spare parts, get the fundamental meaning at the stage of purchasing decisions. The article attempts to signal the issue of the impact of the costs of operational repairs of passenger cars on the development of electromobility in Poland. The considerations were based on proprietary simulations of costs, including the comparison of the same vehicle model equipped with both conventional engine and ecological propulsion units. The aim of the article is to draw attention to the essence of the research issues undertaken and to answer the question, whether in reality the costs of operational repairs of electric vehicles are much lower than those that are fuelled with conventional fuels. The presented research results can certainly be helpful in the purchasing decision-making processes both for individual and group clients.
