    Opis:
    The analysis of energy consumption in a hybrid drive system of a passenger car in real road conditions is an important factor determining its operational indicators. The article presents energy consumption analysis of a car equipped with an advanced Plug-in Hybrid Electric Drive (PHEV), driving in real road conditions on a test section of about 51 km covered in various environmental conditions and seasons. Particular attention was paid to the energy consumption resulting from the cooperation of two independent drive units, analyzed in terms of the total energy expenditure. The energy consumption obtained from fuel and energy collected from the car’s batteries for each run over the total distance of 12 500 km was summarized. The instantaneous values of energy consumption for the hybrid drive per kilometer of distance traveled in car’s real operating conditions range from 0.6 to 1.4 MJ/km, with lower values relating to the vehicle operation only with electric drive. The upper range applies to the internal combustion engine, which increases not only the energy expenditure in the TTW (Tank-to-Wheel) system, but also CO2 emissions to the environment. Based on the experimental data, the curves of total energy consumption per kilometer of the road section traveled were determined, showing a close correlation with the actual operating conditions. Obtained values were compared with homologation data from the WLTP test of the tested passenger car, where the average value of energy demand is 1.1 MJ/km and the CO2 emission is 23 g/km.

    Opis:
    The analysis of the vehicle acceleration process is a current topic based on the aspects related to the general characteristics of the car, its parameters, design, drive unit performance, and the influence of external factors. However, the ability to accelerate is essential from the point of view of the active safety of the car. Often the dynamic parameters are determined on the basis of the car acceleration test carried out on a level road with good surface in terms of the acceleration time is not reliable and the credibility of such results depends on many factors. Therefore in the article, the authors assessed the dynamic and energy parameters of the car motion, in which the intensity of acceleration of the car with different intensities was examined. The acceleration intensity test was carried out from the set initial speed of the car of 45 km/h to the final speed of 120 km/h at a constant gear ratio, and the set intensity of the acceleration process resulted from the constant throttle with a constant deflection of the accelerator pedal. Acceleration was carried out in two variants, the first for a normal internal combustion engine and the second for the same engine but additionally equipped with a short-term boost system. In this way, it influences the increase in power and energy in the car drive system, changing its acceleration intensity. Variable car acceleration intensity was obtained in the range from 0.12 to 1.37 m/s2, and energy consumption at the level of 0.4 to 1.2 MJ in the distance of 1/4 mile. The article proposes a combination of energy parameters and engine power in order to assess the acceleration dynamics, for this purpose, the specific energy consumption of the car was determined, ranging from 0.35 to 2.0 J/(kg∙m), which was related to the engine power, denoting it with the dynamics index. The study focuses on the assessment of the relationship between the specific energy consumption and acceleration of passenger cars in the available powertrain system using a new dynamics index. The proposed dynamics index combines the energy and dynamic parameters of the car to be able to objectively quantify the acceleration process.

    Opis:
    W artykule przedstawiono wyniki badań eksploatacyjnych systemu elastycznych paneli fotowoltaicznych za-mocowanych na dachu autobusu miejskiego. W ciągu dnia system PV zasila elektryczne odbiorniki i doładowuje akumulatory. Obiektem badań był autobus miejski Mercedes Conecto 12LF wyposażony w silnik o zapłonie samoczynnym spełniający normę Euro IV. Badania zawierające różne trasy w Lublinie przeprowadzono w ciągu całego roku. Przedstawiono szczegółowe wyniki badań zużycia energii elektrycznej przez autobus. Równolegle pomiary trwały na stanowisku stacjonarnym wyposażonym w takie same panele PV. Pomiary wartości nasłonecznienia i ilości generowanej energii elektrycznej na dachu autobusu porównano z wartościami uzyskanymi ze stacjonarnego stanowiska. System fotowoltaiczny zamontowany na dachu autobusu odbiera średnio w ciągu roku o 18,9% mniej energii słonecznej, niż ten sam system zamontowany na dachu budynku. Bilans energii elektrycznej potwierdzony badaniami rzeczywistymi potwierdził, że 28% zużycia energii elektrycznej na pokładzie autobusu miejskiego może zostać zastąpione energią ze słońca. Prowadzi to do zmniejszenia zużycia paliwa o około 3% i emisji CO2 o około 1,8 t rocznie.
    This paper presents the results on the operation of the system of flexible photovoltaic panels installed on a roof of a city bus. Over day operation, the PV system supplies electricity to electrical receivers and recharges batteries. The research was done for the Mercedes Conecto 12LF city bus fitted with a Euro IV standard diesel engine. The research covered various routes in Lublin over the year. The paper presents detailed electricity consumption in the bus which was accompanied by parallel electricity consumption measurements done on a stationary test stand with identical PV panels. The results on solar radiation and electricity generated on the roof of the bus were compared with those obtained from the stationary test stand. Over the year, the photovoltaic system installed on the roof of the bus received on average by 18,9% solar energy less than the identical system installed on a roof of a building. The energy balance which was supported by real research confirmed that 28% of on-board electricity consumption in a city bus can be replaced by solar energy, which leads to a reduced fuel consumption by about 3% and CO2 emissions by about 1.8 tons per year.

    Opis:
    In Poland, the number of vehicles owned per capita is systematically increasing. There is also a noticeable increase in traffic in large urban agglomerations. This creates a number of problems, such as difficulties in finding a parking spot. Then it becomes necessary to search for a long time to stop, which is correlated with higher emission of harmful substances and energy consumption. The aim of the work is a multi-criteria analysis of the selection of a parking spot at a shopping center focused on travel times, pollutant emissions and fuel consumption. In addition, consideration was given to the selection of the optimal parking spot. The tests were carried out in Real Driving Conditions similar to Real Driving Emissions testing. The procedure, currently used as an extension of the type-approval tests, reflects the actual exhaust emissions from vehicles more accurately than tests under laboratory conditions. Specialized PEMS (Portable Emissions Measurement System) apparatus was used for the measurements.

    The article presents a mathematical model demonstrating the synergy of HEV energetic machines in accordance with the model predictive control. Then the results of road tests are presented. They were based on the factory control of the above-mentioned system. The results of the operating parameters of the system according to the factory control and the results of the operating parameters according to the model predictive control were compared. On their basis, it could be concluded that the model predictive control contributed to changes in the power and electrochemical charge level of the energy storage system from 50.1% (the beginning) to 56.1% (the end of course) and for MPC from 50.1% (the beginning) to 59.9% (the end of the course). The applied MPC with 13 reference trajectories (LQT) of power machines of the series-parallel HEV allowed for fuel savings on the level of 4%.

    Opis:
    In a regular drive system, with an internal combustion engine, vehicle braking is connected with the unproductive dissipation of kinetic and potential energy accumulated in the mass of the vehicle into the environment. This energy can constitute up to 70% of the energy used to drive a vehicle under urban conditions. Its recovery and reuse is one of the basic advantages of hybrid and electric vehicles. Modern traffic management systems as well as navigation systems should take into account the possibility of the energy recovery in the process of regenerative braking. For this purpose, a model of a regenerative braking process may be helpful, which on the one hand will enable to provide information on how traffic conditions will affect the amount of energy dissipated (wasted) into the atmosphere, on the other hand will help to optimize the route of vehicles with regenerative braking systems. This work contains an analysis of the process of the regenerative braking for the urban traffic conditions registered in Gdańsk. A model was also presented that allows calculating the amount of energy available from the braking process depending on the proposed variables characterizing the vehicle traffic conditions.

    Opis:
    One of the many important challenges of the modern world is the greenhouse effect of CO2. It is necessary to implement solutions that will eliminate it. Since the easiest way to eliminate the greenhouse effect is to reduce hydrocarbons fuel consumption, it is important to evaluate the fuel (energy) consumption in long term operation. The article presents a proposal for the use of the so-called vehicle energy footprint. The method of creating such a trace is presented and illustrated with specific results of data analyzes. The data is publicly available, which means that the presented method can be independently verified. It has also been shown that the use of the method not only organizes the analyzes, but also leads to information that cannot be obtained with other methods. It therefore seems that an attractive tool has been developed for future applications.

    Opis:
    Major markets across the European Union (EU) are concentrated on rapid development of electromobility. This policy is demonstrated - among others - by recent sales of electric cars: within the past 3 quarters of 2018 - 24.7 thousand electric cars have been registered in Germany, 20.3 thousand in France, 15.3 thousand in the Netherlands and 31.4 thousand in Norway. Unfortunately, only 867 EVs have been registered in Hungary, 469 in the Czech Republic, 468 in Romania, 411 in Poland and 348 in Slovenia. Unit energy consumption of electric cars was often defined in NEDC cycle. In real conditions of road traffic, it may differ from values recorded in a drive cycle. The article presents results of a study on energy consumption of electric cars in Poland along RDE (Real Driving Emissions) testing route in terms of vehicle energy consumption per drive unit (km, 100 km). The use of fuel cells in cars may bring a change in the type of used vehicles in the long run. Both globally and in the EU wide-ranging actions are undertaken to implement fuel cell technology. Also, the infrastructure of hydrogen filling stations is developed. At present the most rapidly developing country in this area is Japan. The article addresses the issue of energy consumption per drive unit by cars equipped with fuel cells as both type of vehicles, i.e. EV and FCV use electric motors. The article also discusses infrastructure development in the EU and Poland, charging and fuelling of the said vehicles, respectively.
