Opis:
The interaction of real and virtual devices is an important point in the design and development of control system. The central part of an embedded control system is a controller and it needs input devices and output sensors for realization of the control. The proposed approach allows using a real controller with its specific programming tools and languages for intelligent software development and virtual measurement and sensor devices realized in a computer environment. Different wireless compounds are necessary for intelligent embedded devices for transport system control. For this reason a wireless communication network is needed to ensure the data transmission between the controller and supervisory control and data acquisition system. The purpose of this paper is to propose an approach for interaction of real, embedded and virtual devices in electric transport control systems. The main tasks are: to analyze objects and functional dependencies of an electric transportation control system, to develop a control algorithm with the interaction of real and virtual devices, to ensure a wireless connection for the data transfer from the controller to the supervisory control and data acquisition system, to define the method of transmitted data processing. Computer and practical experiments, with real and embedded devices, and the results analysis will be described the paper.

The article presents, in a multifaceted manner, the changes that occurred in urban electric transport in Ukraine after 1991. The purpose of the article is to research the diversification of the degree and directions of development and transformation of urban electric transport systems in the context of the transport policy. The legal and financial conditions for the functioning and development of the system are discussed, and a SWOT analysis of the current situation is carried out. In order to assess the direction of the changes occurring on individual networks, a synthetic index was used, constructed on the basis of the statistical data from 25 years available. The research has shown that in 1991‒2016, in the vast majority of Ukrainian cities there was a regression in urban electric transport, the largest in the east of Ukraine. That was of a bipartite nature: in the first years it practically applied to all networks, later a polarization in cities occurred ‒ in parts of cities the situation of urban electric transport has improved slightly. In the context of numerous diagnosed problems, the challenges faced by urban electric transport in Ukraine were indicated.

Opis:
Purpose: To highlight the key trends in the transportation industry and the role of emerging technologies and digital transformation in acceleration of value creation. The conceptual framework suggests how such transformation could be implemented. Design/methodology/approach: Research in a focus group was carried out where selected digital transformation frameworks were reviewed, and one was selected as the most applicable to the transportation industry. The selected framework was adopted for the transportation industry. Findings: 1. Value creation should be positioned as the key objective of transformation. 2. Digital transformation is not so much about technology as it is about people. 3. The staged approach towards transformation allows it to be paced with account being taken of the maturity of technology as well as the maturity of competencies across the organization. For a successful digital transformation, the organization invests in development of digital capabilities. Moving towards digital means a mindset shift, cultural change and adoption of new methods of working. Research limitations/implications: Transportation companies are at the early stage of transformation at such a scale. The case studies on successful transformations are limited. Therefore, experience is gathered mainly by the test and learn process. It is recommended that findings are validated with a wider group of experts when transformation matures. Comparing the same framework usage in other industries can also offer additional learnings to be considered by change leaders. Originality/value: Transportation industry is in a process of transformation towards connected, electric and autonomous solutions, accelerated during the COVID-19 pandemic. The presented framework, adopted for the transportation industry, offers a practical tool for executives and change leaders to lead the transformation.
Cel: wyodrębnienie kluczowych trendów w branży transportowej oraz roli przełomowych technologii i transformacji cyfrowej w tworzeniu wartości w branży. Przedstawiony model koncepcyjny transformacji cyfrowej stanowi praktyczne narzędzie, które mogą wykorzystać liderzy transformacji i agenci zmiany. Metodologia: przeprowadzono badania z grupą fokusową, w której wzięło udział 8 ekspertów. Dokonano przeglądu wybranych modeli transformacji cyfrowej. Grupa wyselekcjonowała jeden model, który następnie został zaadoptowany do branży transportowej. Wyniki: 1. Tworzenie wartości powinno być nadrzędnym celem transformacji. 2. O sukcesie transformacji cyfrowej decyduje nie tyle technologia, ile ludzie. 3. Etapowe podejście do transformacji pozwala nadać jej tempo z uwzględnieniem dojrzałości technologii oraz dojrzałości kompetencji w całej organizacji. Aby transformacja cyfrowa zakończyła się sukcesem, organizacja powinna inwestować w rozwój kompetencji cyfrowych. Przejście w kierunku cyfryzacji oznacza zmianę sposobu myślenia, zmianę kulturową i przyjęcie nowych metod pracy. Ograniczenia/implikacje badawcze: firmy transportowe są na wczesnym etapie transformacji na niespotykaną dotąd skalę. Informacje dotyczące studium przypadków udanych transformacji w tym obszarze są ubogie, brakuje ugruntowanych wzorców. Dlatego doświadczenie jest gromadzone głównie w procesie testowania i uczenia się. Zaleca się, aby wyniki zostały zweryfikowane z szerszym gronem ekspertów wraz z postępem transformacji. Porównanie wykorzystania tego samego modelu w innych branżach może również dostarczyć dodatkowych informacji, użytecznych dla liderów zmiany. Oryginalność/wartość: branża transportowa przechodzi transformację na olbrzymią skalę, dążąc do rozwiązań zintegrowanych, elektrycznych i autonomicznych. Proces ten przyspieszył podczas pandemii COVID-19. Przedstawiony model, zaadaptowany do branży transportowej, stanowi praktyczne narzędzie dla liderów zmian do przeprowadzenia tejże transformacji.

Opis:
Purpose. To develop the fuzzy model of distribution of excess regenerative energy in traction and external power supply systems allowing to exercise effective operation of the power equipment. Relevance. For effective distribution of excess regenerative energy in systems of electric transport, as well as for systems equipped with stationary stores of energy and inverting traction substations with regulators of output voltage it is necessary to solve a number of the problems with high degree of uncertainty demanding taking into account a set of random factors such as the modes of power lines and traction loadings. These factors have to be considered in operation for choosing the rational modes of energy stores, inverters and regulators of voltage on buses of substations to provide the rational conditions for energy regeneration on electric transport. Scientific novelty. The control system of energy storage devices, inverters and traction substation output voltage regulators, designed on the basis of fuzzy logic, can provide the necessary conditions for the regeneration on electric transport on sections with a shortage of traction power consumption and allows to optimize the distribution of excess braking energy of transport vehicles. It is achieved by determining the rational relationship between the components of the excess current of regeneration in real time, which can ensure a minimum of power losses of regenerative energy in traction and external power supply systems. Practical importance. The use of the developed approach is effective under the conditions of incomplete information received by measurement systems and on the basis of additional studies it can allow to minimize rated capacity of stores, inverters and traction substation output voltage regulators that could reduce the costs of modernization of existing sections and electrification of new electric transport systems.

The thermal management system is the one most important unit in the electric car which controls temperature of electric devices by obtaining a stability of their operation in different load and ambient conditions. For the other side the removable pack installed in the closed cradle for easier service during exchange of the modules should be cooled by the air. It is also better for safety during exploitation for the vehicle parts and people. The paper presents the proposal of ventilation of battery packs, assumptions of the battery pack cooling system, mathematical model of heat exchange and graphical results obtained from simulation carried out using the CFD program. During modelling it took into account two models: two-dimensional and three-dimensional for evaluation of the air flow and cooling rate of the battery modules. It was assumed four modules in one row of the cradle with total electric capacity above 4 kWh. The paper shows geometry of the whole battery unit with ventilation passages in 3D configuration. The aim of the work was determination of thermal parameters of the battery modules cooled by the air flow in the close chamber. The proposed cooling model of the cradle with air flow caused by fans in the pipe inlet shows that it is not possible to decrease temperature in the same way of each battery modules.

Opis:
Models of electrical energy storage devices – a battery and a supercapacitor – as well as models of motor and a control system, were used to feature the work of a hybrid electric drive system. The models were adapted to simulate driving with a given driving cycle, in a quasi-static method, with the use of MATLAB-Simulink software. The advantage of this method is that calculations can be done quickly and results can be easily compared. A battery model enables determining voltage and charge level in relation to load current and temperature. The basic parameter of a battery is a nominal capacity. It is a measure of energy stored in the battery, which can be absorbed within discharge time, in conditions of temperature and current. The energy can be absorbed until the minimal voltage is reached in the clips. The article presents simulation of calculations lead that the described electric drive model. The model makes it possible to analyse different concepts of steering the whole system already in the initial phase. In particular, the article presents PMSM model and trajectories of selected parameters during a trapezoidal driving cycle.

Opis:
This paper concerns the estimation of indirect CO2 emissions associated with the use of electric engines in Poland. The indirect production of exhaust fumes emitted by electric cars is determined by two factors: the engine’s power consumption and the volume of the emissions produced when generating power sold by distributors. The current structure of the Polish power system, which is the supplier of the prime mover for electric cars, uses mainly the conventional (high-emission) sources of energy. Thus, using electric cars becomes an indirect cause of the pollution in the atmosphere. Increasing the efficiency of the power production process along with limiting the emission level of the combustion process in conventional power plants is a fundamental and essential solution to reduce air pollution.

Opis:
Electromobility is associated with the ever faster development and introduction of new electric vehicles to the market. They use an electric motor to drive the wheels of the vehicle and the necessary electricity is stored in traction batteries. Electric vehicles have a different construction than traditional vehicles i.e. those powered by internal combustion engines. For this reason, the manner of use, maintenance and service are different. Familiarization with selected operational issues of electric vehicles positively affects the reliability of their use as well as safety and comfort of driving. An important component of electric vehicles is the traction battery. Its proper operation influences the long-term preservation of the initial energy capacity and, thus, the range of the vehicle. The article presents tests of the state of traction batteries of a small electrically powered city vehicle. The vehicle, the batteries and the diagnostic devices used to assess the condition of the battery are described in detail. Based on the literature analysis and the observation of market trends, a fast and effective method of assessment of the technical condition of batteries in electric vehicles is proposed. The method has been tested on the selected vehicle. The technical condition of the battery in the vehicle was assessed after 4.5 years of operation and 30,000 km mileage.

This paper presents the problem of public transport planning in terms of the optimal use of the available fleet of vehicles and reductions in operational costs and environmental impact. The research takes into account the large fleet of vehicles of various types that are typically found in large cities, including the increasingly widely used electric buses, many depots, and numerous limitations of urban public transport. The mathematical multi-criteria mathematical model formulated in this work considers many important criteria, including technical, economic, and environmental criteria. The preliminary results of the Mixed Integer Linear Programming solver for the proposed model on both theoretical data and real data from urban public transport show the possibility of the practical application of this solver to the transport problems of medium-sized cities with up to two depots, a heterogeneous fleet of vehicles, and up to about 1500 daily timetable trips. Further research directions have been formulated with regard to larger transport systems and new dedicated heuristic algorithms.
