W pracy zajęto się problematyką zasobników energii stosowanych w obiektach mobilnych. Szczególnie skupiono się na modelach matematycznych akumulatorów kwasowo- ołowiowych, litowo-jonowych oraz superkondensatorów. Przy wykorzystaniu modelu matematycznego akumulatora kwasowo-ołowiowego przeprowadzono symulację procesu jego rozładowania w programie MATLAB. Zaprezentowano charakterystyki parametrów użytkowych przykładowego akumulatora kwasowo-ołowiowego uzyskane w rezultacie zrealizowanych symulacji. Dokonano także porównania charakterystyk obciążenia stałoprądowego dwóch konkretnych akumulatorów, które uzyskano w wyniku przeprowadzonych symulacji komputerowych, z charakterystykami wykreślonymi na podstawie danych katalogowych producenta, otrzymanych w wyniku realizacji badań fizycznych.

The paper deals with the problems of the energy storage units used in mobile systems. Particular attention is paid to mathematical models of the lead-acid and lithium-ion batteries as well as supercapacitors. The mathematical model of a lead-acid battery enabled simulation of the battery discharging process with the help of the MATLAB software. Based on these simulations the characteristics of operating parameters of an example of a lead-acid battery is presented. Moreover, the DC-current load characteristics obtained in result of the computer simulations for two specific batteries were compared to the ones plotted based on the manufacturer’s catalogue data obtained from the physical tests.

The paper deals with the issues related to correctness of electric energy management – mainly in terms of the proper use of energy storages applied in mobile objects such as electric vehicles. Particular attention has been paid to mathematical models of lead-acid batteries, lithium-ion batteries and supercapacitors. While using the mathematical model of the lead-acid battery, the simulation of the process of its discharge was conducted using the MATLAB software. Characteristics of useful parameters of a model lead-acid battery obtained as a result of the conducted simulations were presented. Verification of the correctness of functioning of the created calculation model was carried by comparing the DC load characteristics of two specific batteries which were obtained as a result of conducted computer simulations, with characteristics determined on the basis of manufacturer’s data sheets received as a result of performance of physical tests. As an additional element verifying the correctness of the functioning of the simulations, the characteristics of battery discharge was determined on the basis of the result of calculations which were performed in accordance with the normative definition of electric capacity of the battery.
