Electric vehicles

Fuel cells and the electric motor are examples of highly-efficient, electric drive trains. Electric vehicles are expected to one day outstrip sales of combustion engines vehicles. Innovative technologies such as fuel cells, electric motors and electric vehicles will influence our future mobility. The market for electric vehicles boasts the most potential.

Fuel cells, electric motors and electric vehicles are currently experiencing a breakthrough. Fuel cells are being used in new applications such as automobiles or laptop computers. Like electric vehicles, fuel cells are still in the development phase however. The potential is far from being exploited. Because a genuine fuel cell boom is anticipated, mass production is already underway. Like fuel cells, the application potential for electric motors and electric vehicles is still in its infancy stage. The discovery of the relationship between magnetic fields and electricity laid the foundation for the electric motor, and thus the electric vehicle. The electric motor that eventually resulted from this discovery is driven by the Lorentz force, which is the force on an electric charge as it moves through a magnetic field. The development of traditional technologies such as fuel cells and the electric motor has led to a rise in environmentally-friendly electric vehicles. Hybrid vehicles are still dominating the market in the segment for environmentally-friendly automobiles however. Utilizing a combination of combustion and electric motors, hybrid vehicles are slimmed-down versions of the electric vehicle.

Fuel cells

Fuel cells are based on the principle of a galvanic process. The composition of a fuel cell is influenced by both electrodes. The fuel cell energy stems from the electrode potential, which is created by the charging of the anode and cathode. The charging results in a potential difference in the fuel cell, which is eventually transformed into electric energy. From its discovery, to today's high-technology status, the fuel cell has experienced an astounding development. Fuel cells are already being used in a variety of applications today. But its impressive career is far from over. Because of their simple operation, the use of fuel cells in electric vehicles represents the market of the future.

The electric motor

Theelectric motor began as an electromechanical transformer. As the description implies, the electric motor is capable of transforming electricity into mechanical energy. The electric motor functions by transforming its mechanical force into motion. Like fuel cell technology, the electric motor is a popular drive train alternative in electric vehicles. The development of the electric motor as a drive train for electric vehicles is still a work in progress however. The first genuine electric motor was produced as early as 1834. Today, state-of-the-art, innovative technologies are still based on discoveries made by researchers nearly 200 years ago, as illustrated by the examples of the fuel cell, electric motor and electric vehicle.

The electric vehicle

While electric motors and fuel cells were originally used in industrial machine applications, electric vehicles are the technology of the future. At the beginning of their development, electric motors were initially used in locomotives . At this point, the focus is on the development of roadworthy electric vehicles. The key drivers of modern research into the electric vehicle are the electric motor's high degree of efficiency and low CO2 output, two factors that are behind current efforts to combat energy resource and climate change issues. The major issue is energy storage , which is the why researches are focused primarily on this aspect. For this reason, hybrid model electric vehicles - the combination of electric and combustion motors - are still in their infancy stage.

Automotive Engineering

Automotive Engineering highlights issues related to automobile manufacturing - including vehicle parts and accessories - and the environmental impact and safety of automotive products, production facilities and manufacturing processes.

innovations-report offers stimulating reports and articles on a variety of topics ranging from automobile fuel cells, hybrid technologies, energy saving vehicles and carbon particle filters to engine and brake technologies, driving safety and assistance systems.

Faster Test For Checking The Efficiency Of The Paints Used As Protection Against Corrosion In The Automotive Industry

Researchers from the Area of Materials Science and Metallurgical Engineering at the Universitat Jaume I (UJI), Spain, have devised a quicker method to evaluate the systems used in the automotive industry to protect the metal chassis of vehicles against corrosion. This new technique allows the time required to carry out such tests to be reduced from two months to just one day.

Variation in Diesel Exhausts Leads to Call for More Thorough Testing

Samples of diesel exhaust particles (DEP) collected from automobiles and forklifts varied widely in both their composition and their toxicity, according to a pair of studies published today in the June issue of the peer-reviewed journal Environmental Health Perspectives (EHP). The studies show that the two samples of DEP have different physical and chemical properties, as well as different mutagenic effects in bacteria and pulmonary toxicity effects in mice. The results confirm that DEP can be highl 07.06.2004 | nachricht Read more

Car not first application for fuel cells

The car will not be the first application for fuel cells. This is one of the conclusions in the doctoral thesis of Robert van den Hoed, which he will defend on 17 May at TU Delft. “My research project confirms that large organisations such as in the automobile industry have trouble implementing radical changes.” A fuel cell powered car as a case to gain insight into radical innovation theory.

Recycling cars

The old breakers’ yards, going for a long time, are soon to disappear. The future is now in recycling components from these vehicles and all as a consequence of a new Directive approved by the European Union. The new law came into being in the Spanish State in December 2002. From February of this year the Royal Decree for the Direction General of Traffic obliges owners of vehicles to obtain a certificate of destruction in order to be legally free of contractual ownership of the vehicle.

More crashworthy cars with opitimization

Optimization is an effective method for enhancing the crashworthiness of cars. In a series of simulations of crash tests at Linköping University in Sweden it was possible to reduce the penetration of passenger space by a third. Every year 47,000 people are killed in automobile accidents in the EU. This is as if a jumbo jet were to crash every third day. Such horrendous figures cry out for ever greater investments in crashworthiness. Modern optimization technique, based on so-called finite e 22.03.2004 | nachricht Read more

Can we be motivated not to take the car so often?

Yes, we can, according to this dissertation from Göteborg University, which deals with the impact of road tolls on car use, factors that influence attitudes to road tolls, and road tolls in comparison with other types of steering mechanisms targeting automobile use. But you have to have a positive attitude toward cutting down on car use (which people rarely have) and you have to plan how to go about it and regularly monitor your progress in relation to a realistic goal.

A sophisticated virtual simulation tool to test-drive new cars

The rapidly increasing demands of today’s car buyers have placed a heavy burden on car manufacturers to constantly innovate. Building prototypes to test innovative car designs is a lengthy, not to mention expensive, process and one that companies keen to retain their competitive edge can ill afford.

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
