“…A similar effect in terms of the amount of power recovered by a vehicle in urban traffic can be found in the publication [50]. The obtained power ranges from 71.3-387 W. Simulation and bench tests carried out in 2019-2020, on the basis of available technologies and control techniques, did not demonstrate a significant improvement in the efficiency of the suspension with energy recovery [51][52][53][54]. For vehicles driving on the road, the surface quality of the middle class ranges from 100 W to 400 W.…”

As awareness regarding ecology increases among drivers, some characteristics of electric vehicles mean that they attract a greater interest. The basic factors determining the demand for electric cars include their pricing, access to charging stations and the cost per 1 kWh. Considering the above, the aim of this paper is to review the current areas of research into renewable energy sources, such as wind and solar energy and energy derived from vertical displacements of the car body associated with road roughness. The use of such solutions will allow the battery to be charged while the vehicle is in motion and extend the time of travel without stopping the vehicle for charging. The publication forms an overview of findings in the area and the scope of the research reported here relate to the most recent research. For this purpose, reviews of academic and industrial literature were carried out.

(1) Background: The present development of transport networks focusses on the better management of fuels and energy and the preservation of the environment. To fulfill these desiderates, some countries have already reconsidered the deployment plans of new highways. This research studies the feasibility of less polluting, quasi-self-powered, intelligent highway infrastructure functional blocks accommodating functions for the future introduction of smart wireless sensor grids and connected autonomous vehicles. Subject of investigation are the possibilities of energy harvesting, and the intelligent management of resources. (2) Methods: the research investigates the main technologies for energy harvesting and recommends an optimal solution. It also proposes a framework for the intelligent, AI-based management of energy and the use of an optimized backup solution relying on 5G beamforming for energy supply of the local wireless sensing network devices; (3) Results: recommendations are made for the best energy harvesting solution, an architecture of the energy management system, an algorithm for energy management and backup solution based on 5G beamforming; (4) Conclusions: the research emphasizes the advantages and drawbacks for different solutions regarding energy harvesting in an intelligent green highway scenario with a focus on the infrastructure developed to accommodate future connected and autonomous vehicles. The term “intelligent highway” must be understood in the automotive industry to describe a network of roads where cars communicate with the infrastructure and among themselves for the purpose of avoiding congestion and performing the seamless operation of services, and a space where cars and infrastructure cooperatively process information for obtaining better road safety, less pollution, and efficient energy management. With the recent recession of conventional fuel availability and the increase in prices, a solution to improving autonomy of both cars and infrastructure might be welcomed.

“…Specifically, it has been reported that the energy potential has values ranging from 46 to 7500 W, as function of vehicle typology, pavement conditions, etc. In [17], the authors analyzed the energy recovery potential of two typologies of Energy Harvesting Shock Absorbers (EHSH), namely those based on ball-screw (BS-EHSA) structure and cable transmission (CD-EHSA). The first one is composed of a nut and a screw coupled with a generator, whereas the second one relies on a steel cable and a pair of pulleys for converting the translational into rotational motion.…”
