Modelowanie zasobników energii elektrycznej dla pojazdów elektrycznych i hybrydowych

This paper presents the prepared mathematical models of electrochemical battery Ni-MH and supercapacitors used to simulate components of hybrid bus propulsion system. The model does not provide a self-discharge process of electric energy storage due to the nature of electricity receiver. Frequent changes of direction and power value make the process of self-discharge must not be taken into account. Prepared models of electric energy storage devices are adapted to simulate specified speed profile by the static method, which has the advantage is speed simulation and ease of comparison between several variants of the propulsion system.
