“…The DACIA Electron automobile based on the mechanical structure of the Dacia Sandero automobile was built by CCIA (R&D Center for the Automobile Industry) at the University of Pitesti with the support of Renault RTR Romania in 2016 and publicly presented in 2017 at the EV Show 2017 [27]. It has a "combined charging system" consisting of the classic plug-in system and a WPT Charging system built by ACER Romania [36] in collaboration with INDA-Eltrac SRL, Craiova [37] (Fig. 8).…”

“…Physical aspects are also emphasized in several studies, as for example in [33]- [35]. In [36] a simulation with interior permanent magnet synchronous motor (IPMSM) shows some advantages of a multi-motor solution. Such solution could be adapted for low autonomy needs as presented in [37].…”

Wireless (contactless) transfer of electric power is a disruptive technology because it abandons wired transmission technology, the only technology used in electrical and electronic engineering until recently, just like in the past animal traction and film photography were replaced by mechanical traction and digital photography. Although revealed at the end of the nineteenth century through Tesla's inventions, it could be applied in practice only in the '80s of the twentieth century, with the development of power electronics and microprocessors. After an introduction and an overview of the operating principles, the paper presents the readiness level reached by this technology, the stage of standardization, Romanian achievements and future prospects for high power applications.

For a vehicle, the knowledge of components, characteristics, performances, and behaviors are some base elements for a successful simulation. Today's tools are offering instruments able to cover a such request and new possibilities appear. Choosing the right ones, representing the entire vehicle as a system of subsystems, integrating as much as possible the parameters of different components, are also few additional elements. For internal combustion engine vehicles, the generation and the transmission of the mechanical power to the wheels imply the usage of specific mechanic parts. From a single engine, the mechanical power is controlled to offer the requested torque and speed simultaneously to the vehicle wheels, passing by clutches and gearboxes. An electric propulsion, generating high torque at zero speed, and covering large speed area, implies less components for the mechanical transmissions. One single gear, a reducer, could cover the entire speed area request of the vehicle. On the other hand, it is possible to approach the generation of the mechanical power to the wheels, by using not only one electric motor, but one for each axle, or, even more, one electric motor for each wheel of the vehicle. This paper presents the usage of numerical simulation in such situations, emphasizing opportunities for onboard energy efficiency improvement, and opening new possibilities for optimization in multiple motor solutions.
