    Opis:
    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.

    Opis:
    In recent years, electric and hybrid vehicles have taken more and more attention due to their apparent advantages in saving fuel resources and reducing harmful emissions into the environment. Even though electric vehicles can solve the ecological problem, their operation is faced with a number of inconveniences associated with a limited driving distance from a single charge due to limited storage of energy from an independent power source and a lack of the required service and repair infrastructure. In hybrid and electric vehicles one of the main parameters is the curb weight, which affects energy consumption, vehicle speed, stability, controllability and maneuverability. In this regard, leading car manufacturers use parts with a low specific weight (non-metallic, aluminum alloys, etc.) in the design and also exclude some units from the design. Due to these technical solutions, the vehicle's operating is improved. One of the groups of parameters to be defined when designing a new electric vehicle is the parameters relating to the electric motor. The purpose of the article is determination of the mechanical characteristics of a two-rotor electric motor during magnetic flux control and assessment of the possibility of organizing the drive of the drive wheels of the vehicle. The electric motor has two mechanically independent outputs. For the study, an electrical equivalent diagram has been developed for the given two-rotor electric motor. A simulation model of the equivalent diagram has been built. Simulating the interaction processes of the rotors with the stator made it possible to obtain data for building the mechanical characteristics for each output of the electric motor. Analysis and processing of the mechanical characteristics data of the electric motors showed the conformity and the range of changes in the torque on each of the rotors when changing their slip and revolution, which are required when building algorithms for the operation of electric motor control systems as part of drives for various purposes. Analysis of the simulation results made it possible to assess the possibility of using the considered two-rotor electric motor for the drive of drive wheels in an electric and hybrid wheeled vehicle.

    Opis:
    The search for new, alternative propulsion and energy sources in transport is one of the economic and technological priorities of the current decade. The modern development of hybrid drives and electric means of transport makes it possible to at least partially diversify conventional drive systems. The study discusses the use of a battery and ultracapacitor in electric vehicles. Simulation analyzes of energy flow were performed using the solutions of electric drive systems and various energy storage control algorithms. The research was carried out in relation to the use of braking energy, its con-version into electricity and its storage in a battery or ultracapacitor. The operating conditions of the battery and the ultra-capacitor were assessed in terms of specific energy consumption while driving. The article proposed the use of a drive system connected in series, the last link of which was an ultracapacitor. Such a solution significantly reduced the use of the battery as well as its regular charging-discharging. At the same time, it required the use of a high-capacity ultracapacitor, which contributed to increasing its charging time. The analyzes were carried out using standardized research tests as well as tests in real traffic conditions. The research was carried out with the use of the AVL Cruise software for the analysis of energy flow in vehicles; a middle class passenger vehicle was selected for the tests, equipped with an electrochemical battery and – in the next stage of the research – an ultracapacitor. Three research models were used: I) typical electric drive system; II) a system with the use of ultracapacitors ran by a simple control algorithm; III) a system with the use of ultracapacitors with an advanced control algorithm (the algorithm took into account the change of driving conditions to the ultracapacitor charging conditions). The advantages of using ultracapacitors in the electric drive of a vehicle were demonstrated, especially for results obtained in real traffic conditions. Analyzing the simulation tests results allowed to determine the most advantageous options of utilizing these systems, in particular in the aspect of increased possibilities of algorithms controlling the flow of electricity in the drive system.

    Opis:
    The fleet of electric vehicles is systematically growing. Many passenger car manufacturers are already reporting that after 2030, vehicles equipped with electric propulsion will account for half of the models produced. Vehicles equipped with an electric drive include: battery-powered electric vehicles, hybrid electric vehicles and fuel cell electric vehicles. Over the years, these vehicles have undergone constant change. The aim of this paper was to review trends in the development of pure electric vehicles and plug-in hybrid vehicles.

    Opis:
    W obecnych czasach coraz bardziej niepokoi ocieplenie klimatu. Jest ono wynikiem, między innymi, gromadzenia się nadmiernej ilości gazów cieplarnianych, w tym CO2. Z inicjatywy obrońców środowiska powstały w ramach Unii Europejskiej dokumenty, stanowiące wytyczne do obniżania emisji szkodliwych spalin, wydalanych przez masowe ilości pojazdów, poruszających się po drogach Europy i nie tylko. Wytyczne te, przyjęte przez państwa Unii, wskazują na konieczność - w zakresie zasilania pojazdów - na przechodzenie od tradycyjnych paliw kopalnych, na rzecz różnych, mniej szkodliwych dla środowiska kuli ziemskiej. W opracowaniu zaprezentowano tradycyjne paliwa do samochodów, tendencje w zakresie upowszechniania ich mniej toksycznych alternatyw oraz akty normatywne, wskazujące kierunki badań nad ich wdrożeniem. Zwrócono uwagę, na istniejący w Polsce stan w zakresie infrastruktury technicznej do dystrybucji nowych rodzajów paliw. Wymieniono etapy odejścia od tradycyjnej tzw. benzyny, na rzecz przede wszystkim pojazdów hybrydowych i elektrycznych. Zaprezentowana w skrócie problematyka bazuje na opracowanych pod kierunkiem autora, zaimplementowanych fragmentach pracy magisterskiej [18]. Analiza stanu wdrożenia nowych technologii zasilania pojazdów została pokazana na podstawie wywiadu z przedstawicielem ochrony środowiska i ankietyzacji, przeprowadzonej z pracownikami stacji paliw w mieście Tarnowskie Góry i jej okolicach.
    Nowadays, concerns about climate warming are becoming more and more intense. This is due to, inter alia, the accumulation of an excessive amount of greenhouse gases, including CO2. The initiative of environmentalists resulted in preparing documents within the European Union, which constitute guidelines for the reduction of harmful exhaust emissions, released by mass quantities of vehicles on the roads of Europe and beyond. In terms of powering vehicles, these guidelines, adopted by the EU countries, specify the need to change from traditional fossil fuels to various, less harmful to the environment, the globe. The paper presents traditional car fuels, trends in the dissemination of their less toxic alternatives and normative acts indicating the directions of research on their implementation. The attention was paid to the state of the art in Poland in terms of technical infrastructure for the distribution of new types of fuels. The stages of resigning from the traditional so-called gasoline for the benefit of hybrid and electric vehicles in particular are specified, as well. The issues presented in short are based on the parts of the master’s thesis prepared under the supervision of the author (Morawiec R., 2022). The analysis of the implementation status of new vehicle power technologies was shown on the basis of an interview with an environmental protection representative and a survey conducted with employees of a petrol station in the city of Tarnowskie Góry and its vicinity.
