  • Important factor in political decision-making is a public opinion as well. Therefore, it is very important to raise global ecological awareness and wider public education regarding ecology. Goal of this book is to bring closer to the readers new drive technologies that are intended to environment and nature protection. The book presents modern technique achievements and technologies applied in the implementation of electric vehicles. Special attention was paid to energy efficiency of EV's. Also today's trends, mathematical models and computer design elements of future cars are presented....

  • The idea of combining electrical engines and internal combustion (IC) engines has a long history. In 1901 J. Lohner and F. Porsche had already presented a first hybrid electric vehicle (HEV). But this revolutionary concept did not reach full maturity because the electrical components were not developed. The main concern was the battery, a high-performing battery system with acceptable long-term endurance was not available at the time. The battery of the vehicle shown in Figure 1 had a weight of not less than 1800 kg. It was not until the end of the twentieth century that HEVs became a...

  • There are different degrees of hybridization from microhybrids to extended-range electric vehicles (E-REVs). The complete range between nonhybridized vehicles and pure battery electric vehicles (EVs) is covered. Depending on the degree of hybridization, there are different functionalities available. Table 1 shows the functionality for full hybrid electric vehicles (full HEVs), plug-in hybrid electric-vehicles (PHEV Full HEV, full heavy electric vehicles; PHEVs) with 10 or 40 miles electric-only range, and E-REVs. ...

  • An electric drive is the electromechanical system that converts electrical energy to mechanical motion. Being a part of automatic equipment, it acts together with the driven object, such as a machine tool, metallurgical, chemical, or flying apparatus, domestic or medical device. Electric drives area includes applications in computers and peripherals, motor starters, transportation (electric and hybrid electric vehicles, subway, etc.

  • The rapid development of science and technology leads to improvement of human life, but also creating of new crisis situation. Mankind is confronted with risks that have not been seen before in human history. Global worming is one of the typical examples. Although ma‐ jority of the experts that are studying climate changes claim that global worming is a fact and that it is caused by human, there are also scientists that doubt those statements. One of the main problems related to critical situations is – mater of responsibility.

  • History At the beginning of the automotive century, around 1900– 1910, battery electric vehicles (BEVs), cars with steam engines, and cars with gasoline engines coexisted. They were competing with respect to power, comfort, and maintenance. As described by R. H. Schallenberg, it took the electric starter and the starting, lighting, and ignition (SLI) system (created by Charles Kettering on the demand from Henry Leyland for the 1911 Cadillac Model Thirty) to improve the comfort in use of the gasoline engine vehicle sufficiently to outperform others. ...

  • As manufacturers move to meet the expanding dem~d in batteries for electric-vehicle (EV) applications, there is a need to develop and apply test schemes that provide a true measure of battery performance. The Simplified Federal Urban Driving Schedule (SFUDS) is one of several such d~ty profiles that have been derived from extensive studies of urban vehicle duty. Accurate implementation of the SFUDS is, however, difficult because the load is specified in terms of power and is varied every few seconds. This necessitates a sophisticated control strategy, combined with high-speed monitoring. ...

  • The attributes which are essential for a battery to be successful as the energy store for an electric vehicle are reviewed. These are then matched against the substantial advances in the technology of valve-regulated lead–acid ŽVRLA. batteries that have been posted during the course of the technical programme of the Advanced Lead–Acid Battery Consortium ŽALABC.. A project which was designed to draw together several desirable features, identified during the early years of the ALABC programme, into a test battery has provided much useful information. ...

  • Amidst the welter of publicity devoted to the newer battery chemistries, the remarkable progress made by leadracid battery technologists in response to the needs of the emerging electric-vehicle market has tended to be overlooked. The flooded design of battery, launched by Gaston Plante around 1860, has given way to a valve-regulated variant which has a history dating only from the 1970s.

  • The design, construction and testing of valve-regulated lead/acid cells with grid designs optimised for high-rate partial state-of-charge cycling for hybrid electric vehicles are described. Computer modelling was used to develop the grid designs. This showed that designs with opposed tabs and terminals on the top and bottom of the cell were likely to have the best performance not only in terms of grid conductivity but also for uniformity.
