bility and energy models.

Global energy policies considered for the next few years are aligned with three key topics, that is, the reduction of polluting emissions, the increase in the use of renewable sources and the increase in energy efficiency. In this context, the electrification of the transport sector is considered one of the most important lines of action. In fact, the transport sector accounts for one third of the world's energy consumption, and more than 90% of this energy is cov‐

Indeed, the electric vehicle or plug-in hybrid electric vehicle plays a fundamental role, not only because of its advantages in terms of energy conversion efficiency, or because of its ability to reduce emissions of greenhouse gases and air pollutants, but also because of the high potential for the introduction of renewable sources in the electricity sector. Thereby, the electric vehicle should be interpreted as a transversal element towards more sustainable mo‐

However, the success of the electric vehicle depends both on its suitability for the new mobili‐ ty paradigm in general and on its technical and economic viability in particular. In this regard, questions related to the type of electric vehicle to be promoted, the autonomy, the perform‐ ance, the recharging infrastructure and the impact on the electric network are issues that must be addressed and solved. Indeed, electric and hybrid vehicles continue to be high on academic and industrial research agendas to promote their final implementation and immense usage in clean urban environments, and this is precisely the purpose of this book, that is, to contribute to the literature about current research and development activities related to new trends in

In this regard, selected authors have been invited to contribute their original research work as well as provide literature review articles that illustrate the current efforts that are taking place towards related technologies, the powertrains and the deployment point of view re‐

The first section includes current studies that reflect the increased demands on electric vehi‐ cle technologies highly related to design factors closely linked to powertrain efficiency and performance. Thus, model-based design processes for electric vehicle conversion, as well as the study of motion dynamics controls, are included in this section. Also, as a critical com‐ ponent for powertrain improvement, current battery system management and supervision

The second section focuses on the electrical powertrain, especially on the electric motor, as the core of the electric vehicle. Indeed, the ideal characteristics of an electric motor for trac‐ tion in electric and hybrid vehicles are high torque and power density, wide range of

electrical powertrains, from their components to integration into the infrastructure.
