Über dieses Buch

The book presents – based on the most recent research and development results worldwide - the perspectives of new propulsion concepts such as electric cars with batteries and fuel cells, and furthermore plug in hybrids with conventional and alternative fuels. The propulsion concepts are evaluated based on specific power, torque characteristic, acceleration behaviour, specific fuel consumption and pollutant emissions. The alternative fuels are discussed in terms of availability, production, technical complexity of the storage on board, costs, safety and infrastructure.

The book presents summarized data about vehicles with electric and hybrid propulsion.

The propulsion of future cars will be marked by diversity – from compact electric city cars and range extender vehicles for suburban and rural areas up to hybrid or plug in SUV´s, Pick up´s and luxury class automobiles.

1. Mobility: Conditions, Requirements, and Scenarios
Abstract
In 2013 there were more than 7.3 billion human beings and 1.18 billion automobiles on the planet. Although most people live in urban areas, the number of megacities (cities with >10 million residents) is rapidly increasing. Figure 1.1 illustrates the situation as of January 2015.

2. Thermal Engines
Abstract
The feasibility and limitations of thermodynamic cycles for the transformation of heat to work are considered in this chapter in relation to development scenarios for propulsion systems. As described in Sect. 1.​3, these scenarios include thermal machines as direct propulsion systems, propulsion modules in hybrids, and on-board generators for electric energy. Thus, the efficiency of a thermal engine is considered in reference to its function as a propulsion system module, and not for a broad range of load and speed.

3. Alternative Fuels
Abstract
Transformation of the chemical energy of a fuel with the general structure CmHnOp is possible in two ways:

4. Electric Propulsion Systems
Abstract
Taking into account traffic flow, the greenhouse effect, pollutant emission, and noise emission, it seems that electric mobility is the best alternative for transport in urban areas. Nevertheless, as shown in Chap. 1, these unique characteristics are prejudiced by severe disadvantages regarding the sources of electric energy (Fig. 1.4) and its storage on board vehicles (Fig. 1.17).

5. Combinations of Propulsion Systems, Energy Sources, Energy Converters, and Storage
Abstract
The assessment of propulsion systems for automobiles in terms of energy demand and energy source, as well as in relation to ecological, technical, and economic criteria, leads to the awareness that a universal configuration is not realistic. The specific benefits of different functional modules are arguments for their effective combination. Development trends are mainly determined by the following aspects:

6. Energy Management in the Automobile as a Complex System
Abstract
The exemplary development of propulsion systems for automobiles, from increased power to decreased pollutant emission, is based on a massive innovation potential directed by requirements, limitations, and acceptance criteria. The true highlight of future automobiles is the management of energy during propulsion and of the energy supply on board. Propulsion forms, energy sources, and modules for energy conversion and storage are combined in different configurations for this aim. An all-purpose and generally accepted automobile is in contradiction to the usual development rules and to natural, economic, technical, and social conditions. The modularization of functional components allows more effective diversification of car types and classes. This diversification follows three principal directions, as illustrated in Fig. 6.1:
