The purpose of the presented work was to find the effectivity of energy conversion in a light-duty vehicle with an electric drive and the accumulation of energy in lead-acid batteries. This type of energy storage is still very popular in a category of small utility vehicles. The chain of energy conversion from the socket in the power grid, through the charging device, to the traction battery was the subject of the research. Furthermore, the impact of vehicle operation on equivalent carbon dioxide emissions into the atmosphere associated with the methods of electricity generation in Poland with a dominant role of coal was investigated. The results were related to the situation in other European countries, in which electricity is generated from various energy sources. Performed research allowed to determine: the energy consumption of motion of the test vehicle including and excluding energy loss in the process of charging, efficiency of the charging device, the energy efficiency of the battery pack and the equivalent of carbon dioxide emissions per each kilometer driven by a vehicle. The analysis of the results of effectivity of energy conversion in an electric vehicle allows to formulate two major recommendations. The first one is a change of the method of electricity generation in Poland to low-emissions power plants. In addition, it would be appropriate to replace lead-acid batteries with newer designs with higher performance. This will reduce energy consumption.
