CO2 reduction exploiting RES for EV charging

2017

The world is facing an urgent need to reduce emissions, limiting pollution for a better quality of life. This objective has to be reached by all cities and governments worldwide. This paper focuses on the field of transportation, which is greatly responsible for air pollution, mainly in cities and urban areas such as towns, airports and seaports. The diffusion of electric vehicles (EVs) enables a significant reduction of air pollutants emitted by combustion engines; however, their recharge can affect the total pollution by their increasing energy demand. A solution is the use of Renewable Energy Sources (RES) to charge EVs. This paper analyzes the feasibility of integrating EVs and RES, foc…

Guidelines and Conceptual Design of the Grounding System of the DTT Experimental Facility

2022

The Divertor Tokamak Test (DTT) is an experimental nuclear fusion reactor currently under construction at the ENEA research center in Frascati and whose first plasma is expected in 2025. The present article shows the conceptual philosophy and the guidelines behind the design of the grounding system of the DTT. The article focuses on the main target of the grounding system and on the main technical standards to refer to for the design.

Improving performance evaluation in a IEEE 802.11 chain topologies through a deterministic setting of backoff values

2010

The chain networks based on the IEEE 802.11 protocol are implied in several applications. Their advantage is the robustness of protocol, but they suffer of performance decreasing due to the so-called hidden node problem. In literature some changes to the protocol have been proposed, but generally they are complex and request important modifications to the protocol structure. In this work, on the contrary, it is proposed an easily feasible 802.11 protocol change. In order to avoid collision, it is shared the channel in transmissions perfectly separated in time. Analysis and simulations, executed in chain networks composed by 4 nodes, will show how the proposed modification increases the perf…

Towards a business model for second-life batteries: Barriers, opportunities, uncertainties, and technologies

2023

Electric vehicles (EVs) and the recent pandemic outbreak give cities a new trend to primarily private and shared mobility with low noise and less air pollution. Crucial factors for the widespread of EVs are the electrical charging infrastructure, driving range, and the reduction of the cost of battery packets. For this reason, there is a massive effort from manufacturers, governments, and the scientific community to reduce battery costs and boost sustainable electrical production and distribution. Battery reuse is an alternative to reduce batteries’ costs and environmental impacts. Second-life batteries can be used in a wide variety of secondary applications. Second-life batteries can be co…
