Opis:
The correct information, including the full braking deceleration of a vehicle, is an essential factor of the road accident process analysis. The aim of the paper was to define and compare the braking properties of the tested Tesla model S electric vehicle by means of the XL MeterTM Pro decelograph and a smartphone as a new alternative method. The measured procedure was the intensive vehicle braking by means of a fully pressed-down operation brake from the different initial velocities. Altogether, 32 measurements were carried out, out of which 16 on the dry surface and 16 on the wet surface. This paper contains the methodology and the results of the performed measurements. The data obtained by an XL Meter TM Pro measuring device were processed by means of the XL Visionä and PC Crash 11.0. software, whereas the data from the smartphone was analysed using the Diagram software. The results and data processed herewith can be useful for the forensic practice.

Opis:
Full electric (FEV) and plug-in hybrid (PHEV) vehicles are promising, forward-looking technologies to reduce greenhouse gas (GHG) emissions and other pollution related to road transport. The powertrain of a FEV is composed of a battery, control electronics and the electric motors. A PHEV has much lower battery capacity but it contains an extra internal combustion engine and gearbox. Many argue that FEVs are more energy-efficient than internal combustion engines. However, this energy needs to be stored in heavy, large-capacity battery packs that require plenty of energy and resources to produce as well as highly polluting rare earth elements mining. In this article, an environmental comparison of FEVs and PHEVs is shown using life cycle assessment (LCA). To make the comparison realistic, two models similar in size and power have been selected: Volkswagen E-Golf FEV and Volkswagen GTE PHEV. Results show that the production of FEVs need more energy and it means more burden on the environment however during the use phase it causes less emissions. Since the local electricity production mix and, in case of PHEVs, the user behaviour highly affects the results, three different countries (Hungary, Poland and Norway) and two different use types are considered. The quantified environmental footprints as well as the break-even distances are presented. Sensitivity of the results towards the assumed conditions during the whole design lifetime of the vehicles is discussed.

Opis:
Recently a huge progress in the field of electrical machines makes them more available for aviation. Assuming a big leap forward of electric technology in the near future, many research institutes around the World examine a revolutionary propulsion system which employs electrical machines. This idea can be a perfect response to a drastically growing air traffic and its demands about emission and fuel consumption reduction. There are already manufactured full electric, ultralight airplanes, which show that the technology is promising and future-proof. What is more it seems to be a key enabler for the development of the other technology that will influence the future of aircraft design and will allow introducing completely new airplane architectures. That is why Institute of Aviation in collaboration with The Ohio State University conducts investigation and analysis on feasibility of using such systems for aircraft propulsion. For this task a completely new tool based on Numerical Propulsion System Simulation (NPSS) environment is being developed. It will enable to analyse the electric devices conjugated with turbine engine as a whole propulsion system in the matter of its performance characteristics. The purpose of this paper is to present some of the most promising ideas and already accomplished analysis of different kinds of architectures. The analysis and optimization of the system, as well as cost effectiveness will be presented.

Opis:
In order to meet the operation requirements of the beam supply with multi-working conditions, multi-modes and high efficiency, a dual-mode hybrid output control method combining phase-shifting and pulse-width dual-mode modulation technology with secondary side series-parallel operation is proposed. In this paper, the structure and working mode of the new dual full-bridge topology are firstly analyzed. Secondly, the main circuit parameters are designed according to the power performance indicators, and the losses under two control modes of phase shift and pulse width are calculated. Finally, comparing the losses of these two control methods, and combining the series-parallel operation mode of the secondary side of the transformer, a dual-mode switching control method of the beam supply is designed. In order to verify the rationality of the dual-mode mixed output control method, a principle prototype with a rated capacity of 2 kW, a rated voltage of 1 800 V and a switching frequency of 50 kHz was used for verification. Experiments show the effectiveness and superiority of the dual-mode hybrid output control method.

Opis:
The article describes a conception of a off-road car, in which the self-ignition motor is planned to be replaced with a single or a group of electric motors. To implement the idea, it is planned to use a off-road Honker vehicle, produced in Poland. The choice has been made according to satisfactory cross-country properties of the vehicle, its reliability achieved by a simple design as well as positively user-rated performance in passing through the obstacles. The main aspect, still to be resolved, is the implementation of one electric motor to propel all wheels or four separate motors (each one for a single wheel). An important issue is the choice of a power supply, which can be a battery unit, recharged with a low power motor-generator. The vehicle will be additionally equpped with an innovational telematics system with its main element – the set of sensors for toxic gases detection and a communication system. Measured data will be transmitted to the headquarters. After aggregating and processing the data, the current information will be sent to each of the vehicles. The article characterises main assumptions of this system.
W artykule opisano koncepcję samochodu terenowego, w którym planowane jest zastąpienie silnika o zapłonie samoczynnym, silnikiem lub zespołem silników elektrycznych. W tym celu planowane jest wykorzystanie, produkowanego w Polsce, samochodu terenowego Honker. O wyborze platformy zdecydowały dobre właściwości terenowe samochodu, niezawodność spowodowana prostotą konstrukcji i pozytywnie oceniana przez użytkowników tzw. „dzielność w terenie”, oznaczająca wysoką zdolność do pokonywania przeszkód terenowych. Podstawowymi kwestiami, które pozostają do rozstrzygnięcia jest zastosowanie jednego silnika elektrycznego do napędu wszystkich kół – podczas jazdy terenowej, lub zastosowanie czterech silników (po jednym na każde koło). Ważnym aspektem jest wybór źródła zasilania, którym może być zespół akumulatorów, doładowywanych przy użyciu agregatu prądotwórczego małej mocy. Pojazd będzie dodatkowo wyposażony w innowacyjny system telematyczny. Jego głównym elementem będzie zestaw czujników do wykrywania niebezpiecznych gazów i system łączności. Dane pomiarowe będą transmitowane do centrali. Po zagregowaniu i przetworzeniu danych, aktualna zagregowana informacja będzie przesyłana do poszczególnych pojazdów. W artykule scharakteryzowano główne założenia tego systemu.
