Strategic Approach for Electric Vehicle Charging Infrastructure for Efficient Mobility along Highways: A Real Case Study in Spain

The Electric Vehicle (EV) market has been growing exponentially in recent years, which is why the distribution network of public charging stations will be subject to expansion and upgrading. In order to improve the public charging infrastructure, this paper aims to develop a model capable of analyzing the current situation of a stretch of highway, identifying the congestion points, created by the formation of queues at the charging points. A specific section of a highway in Spain was selected as a case study to evaluate the performance of the model, allowing for rigorous testing and thorough analysis of its performance in a real-world scenario. The first step is to define and evaluate the effects of factors affecting EV consumption, such as the slope of the road, weather conditions, and driving style. Subsequently, a simulation model is developed using the agent-based simulation software AnyLogic, which simulates the journey of a fleet of electric vehicles, taking into account the battery charging and discharging process. Based on the obtained results, the charging infrastructure is improved to minimize the total travel time of an electric vehicle on a long-distance trip

Literature Review - Mobile Electric Storage System (MESS): Use Cases and Applications

Nowadays, renewable energy is a fundamental technology for the reduction of global carbon emissions. Due to the low penetration of intermittent renewable sources, most grids today are flexible and fragile. Utility-scale energy storage systems can improve grid stability and solve problems of intermittence by connecting more renewable energy sources to the energy market. This paper will present a literature review of battery systems, specifically mobile, dubbed Mobile Electric Storage System (MESS). Various services in distribution systems can be provided with MESS, they can not only shift power from renewables to peak load times, but also provide reactive power support, control grid voltage and frequency stability in smart grids. Finally, it presents a comparison between electric storage systems stationary and mobile, demonstrating how their mobility offers operational flexibility to support geographically dispersed loads in outage areas

Energy Consumption Calculating in Electric Vehicles Considering Road Gradient

Nowadays the transport electrification represents one of the fundamental aspects for reducing pollution. The shift to Electric Vehicles (EVs) is proceeding moderately in Europe. The main reasons that delay the electrification of transport are related with long charging times and the reduced range of EVs. For these reasons calculating energy consumption plays a key role in reducing range anxiety by providing the driver with an accurate estimate of remaining range. This paper presents a model for calculating the energy consumption of EVs on a predefined route. The developed model is a physical model based on EV dynamics and modeling that also takes into account the influence of road slope. The developed model was tested on the five most popular models in Italy

Transport Service Electrification in Developing Countries

Considering the new stringent constraints proposed by public authorities, decarbonization became a key trend in the last years. Transport sector still represents one of the most pollutant fragment. Even if several countries start their process of decarbonization through the introduction of several Electric Vehicles in their public services, still, for several countries, especially the developing ones, transportation represents a hard to abate sector, which generally uses outdated and pollutant vehicles, discouraging the use of public transport and facilitating the creation of traffic congestions. Basing on these considerations, this work want to implement a simulation for a public service in a developing country, evaluating if it is possible to perform a long trip using an electric minibus. Therefore, a case study will be implemented highlighting the barriers of the transport electrification in this area, producing results on consumption and reliability of the service. Finally, an environmentally sustainable solution to power the service will be proposed to highlight the potential of electrification in the area

Different Demand for Charging Infrastructure along a Stretch of Highway: Italian Case Study

Electric Vehicles (EVs) play an important role to reach the global ambitious climate and air quality goals. The timely implementation of adequate EV charging infrastructure is critical to the success of the ecological revolution. However, at the same time, EV adoption is the main driver for the business case of EV charging infrastructure. In order to implement an optimal charging infrastructure, it is important to consider all the relevant factors which influence the charging demand of EVs. This paper aims to evaluate the charging infrastructure on highways by considering several factors that impact electric vehicle deployment. To do this, a simulation model is developed. An agent-based approach, according the AnyLogic software tool, is used to emulate the human behavior and its impact on load demand due to EV charging. Furthermore, a discrete event method is applied for simulating the queue in the charging stations. Therefore, an electric vehicle routing algorithm is developed, which analyses the current status of the charging infrastructure along the highway considering an EV traffic flow travels in the highway in one day

This paper explores the use of piecewise linear regression for modeling and analyzing electric vehicle charging curves, with a focus on optimizing charging efficiency for Charging Point Operator (CPO) and energy providers. Through a case study, we show the effectiveness of this method in informing more efficient Vehicle-to-Infrastructure (V2I) strategies and contributing to predictive Vehicle-to-Grid (V2G) design. A method is proposed to group and characterize charging stages, improving the design of charging infrastructure for more sustainable electric vehicles integration

Water Transport Decarbonization: Preliminary Case Study in Venice

In order to improve the current existing water public transport service, this paper aims to electrification of water taxis in Venice, a widely used means of transportation in the lagoon city by tourists. In particular, the section that connects San Marco square to Marco Polo airport, which is the one with the longest distance, is analyzed. Following a brief introduction to landscape water transport and its infrastructure in the city of Venice, this paper presents the modeling of the electric water taxi taking into account the needs and peculiarities of the boat and of the city itself. Subsequently, an agent-based approach using the AnyLogic software tool simulates the round trip, calculating energy consumption and analyzing the state of charge profile

Literature Review on Wireless Charging Technologies: Future Trend for Electric Vehicle?

Transportation is considered as the largest contributor to greenhouse gas emissions. Recently, many European countries and the World Health organization (WHO) have passed laws to reduce road vehicles emissions, which are responsible for 60.7% of European road transport air pollution. The electrification of vehicles required various charging infrastructure options. One of the state-of-the-art technologies is dynamic wireless charging systems (to deliver energy to the EV in motion). Thus, this paper summarizes distinct static and dynamic wireless charging technologies for electric vehicles. Analyzing different wireless power transfers and their limitations shows that the static wireless charging stations in house garages or open parking lots and dynamic charging infrastructures in smart roads or highway-charging lanes will be promising solutions in the near future to make electric vehicle charging easier or without making stops for recharging
