Opis:: Vehicles with electric propulsion systems are increasingly more often equipped with solutions that improve their drive system’s efficiency. The latest vehicle model with a fuel cell hybrid system – Toyota Mirai was used in this experiment. The design of this vehicle is similar to that of hybrid vehicles in many aspects. However, new fuel cell technologies are being developed for automotive use, including compressed hydrogen tanks and control systems. The article presents an analysis of a fuel cell operation during vehicle start-up and driving, with particular emphasis on the hydrogen injection strategy of the three fuel injectors used in the fuel cell. The fuel cell interaction with the high-voltage battery has also been characterized. It has been shown that increase in the electrical supply voltage of the vehicle’s electric motor can be observed at high torque values of the electric motor. The maximum voltage gain – approximately three times (up to about 650 V) – allows for double the torque of the drive system compared to the standard value.

Opis:: Aim of the paper is to demonstrate evolution of Electric Vehicles (EV) and their infl uence on the Smart Grid (SG). Starting from USA defi nition of the SG considering the fi fth- and sixth- properties of the SG: It accommodates all generation and storage options and it enables new products, services and markets. We can determine EV role in the SG operation. Contemporary we can distinguish following types of the EV: HEVS – hybrid electric vehicles with motor and use batteries with no using electricity from external source, Pure EVs – running on electric motor powered by batteries that are recharged by plugging in the vehicle, Plug-in PHEVs – can be charged with electricity like engine power EVs and run under engine like HEVs. The most interesting for electric power there are Pure EVs and PHEVs that are consumers and also kind of electricity storage devices (very important in SG). These types may be charged “in home”, using special station with diff erent time of charging; there is also considered charging during the time waiting for change of lights on road nodes (junctions). It is important to mention that EV development infl uence not only on SG, social- and climate- environment but also on development of new branch of industries producing equipment necessary for EV operation.
Celem niniejszego artykułu jest zaprezentowanie rozwoju pojazdów elektrycznych oraz ich wpływu na sieci inteligentne (Smart Grid). Według definicji sieci Smart Grid, zaproponowanej przez USA, piątą i szóstą właściwość tych sieci stanowiły odpowiednio: posiadanie możliwości generacji i magazynowania oraz udostępnianie nowych produktów, usług i rynków. Autorzy dążą do okre- ślenia roli pojazdów elektrycznych w operacjach sieci Smart Grid. Wyróżnić można następujące typy pojazdów elektrycznych: HEVs – pojazdy hybrydowe mające silnik i wykorzystujące baterie bez pobierania elektryczności ze źródeł zewnętrznych, EVs – pracujące na silniku elektrycznym zasilanym bateriami ładowanymi przez podłączanie pojazdu oraz Plug-in PHEVs – pojazdy, które można ładować tak jak EVs, ale pracujące jak HEVs. Najbardziej znaczące dla elektroenergetyki są pojazdy typu EVs oraz PHEVs, ponieważ występują one jednocześnie w roli odbiorcy, jak i pewnego rodzaju urządzenia magazynującego. Pojazdy te mogą być ładowane w budynkach za pomocą specjalnych stacji ładujących bądź w trakcie postoju, np. na skrzyżowaniu. Należy podkreślić, że rozwój pojazdów elektrycznych nie wywrze wpływu jedynie na sieci inteligentne, lecz także na środowisko naturalne, społeczeństwo oraz rozwój nowych gałęzi przemysłu wspierających pojazdy elektryczne.

Opis:: Due to limited resources of fossil fuels and overproduction of greenhouse gases, a need for alternative means for vehicle communication appeared. Because of that hybrid electric vehicles, as well as battery electric vehicles, were proposed to replace some of conventional vehicles based on internal combustion engine [3]. To their advantages over conventional cars belong environmental friendliness and better performance (in case of hybrid electric vehicles), but they also suffer from greater purchase costs and limited range (in case of most battery electric vehicles) [4, 6]. Presented work briefly characterizes four types of vehicles equipped with electric motor (mild hybrid, full hybrid, plug-in hybrid and battery electric vehicles) along with generalised presentation of their battery requirements [4, 6]. Further in this work, the lithium-ion (Li-ion) battery working principle was explained, along with characterisation of its limitations due to its design and requirements for inactive components e.g. 4-fold drop in specific capacity and energy density while moving from pure electrode material level to battery level [20]. Next, present Li-ion active components, such as LiCoO₂, LiMnO₂ and LiFePO₄ cathodes and graphite anode along with their capacities and energy densities as well as other characteristic regarding (e.g. environmental friendliness, safety and cost) are shown. Moreover electrode materials e.g. nanocomposite anodes and cathodes, multi-electron cathodes (e.g. Li₂MnSiO₄), as well as Li-metal and Li₄Ti₅O₁₂ anodes, with their advantages and disadvantages were described [15, 20]. Presented article was summarized by gathered opinions of battery electric vehicles users, who share their experience regarding their electric cars in a survey. One can tell that they are fairly satisfied with their purchase and that improvement in range of battery electric vehicles along with predictable government policy regarding electrification of cars are the most important factors when considering purchase of electric vehicle [36].

Opis:: Hybrid electric vehicles (HEVs) have an increasing presence in passenger transport segment. They have been designed to minimize energy consumption and pollutant emission. However, the actual performance of HEVs depends on the dynamic conditions in which they are used, and vehicle speed is one of the key factors. A lot of excess emission and fuel consumption can be attributed to rapid changes of vehicle speed, i.e. accelerations and decelerations. On the other hand, dynamic driving favours energy recovery during braking. This study examines the relationship between HEVs speed, pollutant emission and fuel consumption. The considerations were based on the results of testing vehicles in WLTC and NEDC driving cycles, performed on a chassis dynamometer. The test objects were two light-duty passenger vehicles, one with series-parallel, gasoline-electric hybrid system and the other, used as a reference, with conventional spark-ignition engine. Both vehicles had similar technical parameters and combustion engines supplied with gasoline. The driving cycles were divided into several parts according to the speed range. For each part, pollutant emission and fuel consumption were determined and appropriate values of selected parameters of driving pattern were calculated. Combining the results of empirical research and calculated parameters allowed to obtain characteristics. Their analysis provided valuable insight into the impact of driving pattern on actual emission and fuel consumption of HEV.
