<jats:p>The large-scale introduction of electric vehicles into traffic has appeared as an immediate necessity to reduce the pollution caused by the transport sector. The major problem of replacing propulsion systems based on internal combustion engines with electric ones is the energy storage capacity of batteries, which defines the autonomy of the electric vehicle. Furthermore, considering the high cost of the battery, it is necessary to consider the implementation of command-and-control systems that extend the life of a battery for as long as possible. The topic covered in this article refers to the analysis by modeling and simulation of the efficiency of a hybrid energy storage system (battery–supercapacitor) adapted for an electric vehicle (e-Golf). Based on the simulations carried out, considering that the operating mode corresponds to the WLTP test cycle, the major conclusion was reached that the use of such a system leads to a decrease in energy consumption by 2.95% per 100 km. Simulations of the model were also carried out to obtain the variation in electricity consumption and vehicle autonomy depending on the number of passengers. Electricity consumption if the vehicle is equipped with a hybrid energy storage system increases by 0.67% on average for each passenger (of 75 kg) added and by 0.73% on average if the vehicle is not equipped with supercapacitors. Moreover, the use of the supercapacitor’s properties leads to the reduction in the peaks in energy taken/given by the battery with a direct effect on extending its life.</jats:p>
