Charging Demand

Electric vehicles require sufficient public charging infrastructure. This in turn necessitates detailed information on charging demand. In this paper we present a four-step approach to estimating public charging demand of electric vehicles. Previous methods are limited in their ability to provide differentiated results and adapt to future developments. Therefore, we account for user groups (private, carsharing, commercial), technical developments (vehicles, infrastructure), infrastructure availability, and carsharing development (operational area, business models, autonomous vehicles). Our approach also considers the interactions between these factors and allows for scenario analysis yielding the quantity and spatial distribution of public charging demand. We demonstrate our approach for Berlin, Germany. We find that the majority of public charging demand results from carsharing. This demand is concentrated in the city center, even when carsharing is available citywide. Public charging demand for commercial users is relatively low and located outside the city center. For private users, public charging demand shifts to the city center with an increasing market penetration of electric vehicles and technological advancements (increased range, charging speed). Public demand from private users increases dramatically when private infrastructure is absent. Finally, public charging demand shifts to the city center when private users do not have private infrastructure.

Charging Demand

This study focuses on determining the impacts and potential value of unmanaged and managed uni-directional and bi-directional charging of plug-in electric vehicles (PEVs) to integrate intermittent renewable resources in California in the year 2030. The research methodology incorporates the utilization of multiple simulation tools including V2G-SIM, SWITCH, and GridSim. SWITCH is used to predict a cost-effective generation portfolio to meet the renewable electricity goals of 60% in California by 2030. PEV charging demand is predicted by incorporating mobility behavior studies and assumptions charging infrastructure and vehicle technology improvements. Finally, the production cost model GridSim is used to quantify the impacts of managed and unmanaged vehicle-charging demand to electricity grid operations. The temporal optimization of charging sessions shows that PEVs can mitigate renewable oversupply and ramping needs substantially. The results show that 3.3 million PEVs can mitigate over-generation by ~4 terawatt hours in California—potentially saving the state up to about USD 20 billion of capital investment costs in stationary storage technologies.

Purpose This paper aims to address socio-spatial challenges facing the sustainable regeneration of the 19th-century historic covered Attaba market. One of the few remaining historic market buildings in Cairo. Understanding these challenges is crucial as there is a pressing need for these buildings to be included in the national heritage regeneration policies that would foster their role as sustainable socio-economic urban nuclei within the city center. Design/methodology/approach The paper detects the socio-spatial transformation of the Attaba market through the comparison of archival material. This is supported by observations on the current socio-spatial aspects of the market including forms of interactions, conflicts and interventions of various user groups. A number of 30 semi-structured interviews with traders of the Attaba market were conducted inside the market, along with in-depth observations carried out between 2016 and 2018. Finally, information about local policies toward the market is obtained through interviews with local officials currently managing the market, namely, the Egyptian Endowment Authority and Cairo Governorate. Findings The findings reveal a lack of clear regeneration policy and a complete absence of public participation in decision-making. These factors erode the crucial role these markets play in revitalizing the city’s socio-economic strength and threaten their tangible and intangible values. Originality/value The paper focuses on one of the understudied building types that, however, represent key opportunities for the sustainable development of their contexts. The paper proposes a framework that can be applied to regenerate the Attaba market and its surroundings. When tested, the framework can be also adjusted and applied to the other historic covered markets in Cairo.

Application of renewable energy sources is a relevant area of energy supply for urban infrastructure. In 2019, the share of energy produced by such sources reached 11% (for solar energy) and 22% (for wind energy) of the total energy produced during the year. However, these systems require an improvement in their efficiency that can be achieved by introducing electric vehicles. They can accumulate, store and transfer surplus energy to the city’s power grid. A solution to this problem is a smart charging infrastructure. The existing studies in the field of charging infrastructure organization for electric vehicles consider only models locating charging stations in the city or the calculation of their required number. These calculations are based on socio-economic factors and images of a potential owner of an electric vehicle. Therefore, the aim of this study is to develop a methodology for determining the location of charging stations and their required number. The calculation will include the operating features of the existing charging infrastructure, which has not been done before. Thus, the purpose of this article is to research the operation of the existing charging infrastructure. This will provide an opportunity to develop approaches to the energy supply of charging infrastructure and city’s power grid from renewable energy sources. The article presents an analysis of data on the number of charging sessions during the year, month and day. This data enable us to construct curves of the charging session number and suggest ways to conduct the next stages of this study. Doi: 10.28991/esj-2020-01251 Full Text: PDF

This paper is to enclave, a policy initiation for development of slow charging station infrastructure and E-rickshaw vehicles registration process in India. EV’s (Electric Vehicles) as the new green nonpolluting vehicle for last mile connectivity within the city limits. At the E-rickshaw market a no of models available, but there is no study done for governing method, rules to follow and provision for charging infrastructure.   E-rickshaw are being considered as a priority option towards sustainable development. These vehicles are the smart choice and encouraged as feeder system for last mile connectivity. E-rickshaw mode has been excluded from NMT (Non-motorized Transport) category and included in Motor Vehicles Act (2014) as special purpose battery operated vehicle. The main objective of the paper is to creating a space for building the charging infrastructure with different tariff and to setup governing rules for E-rickshaw operators.

It is widely accepted that the market uptake of electric vehicles is essential for the decarbonisation of transport. However, scaling up the roll out of electric vehicles (EV) is challenging considering the lack of charging infrastructure. The latter is, currently, developing in an uneven way across the EU countries. A charging infrastructure with wide coverage addresses range limitations but requires high investment with uncertain returns during the early years of deployment. The aim of this paper is to assess how different policy options affect EV penetration and the involvement of private sector in infrastructure deployment. We propose a mathematical programming model of the decision problem and the interaction between the actors of EV charging ecosystem and apply it to the case of Greece from the time period until 2030. Greece represents a typical example of a country with ambitious targets for EV penetration by 2030 (10% of the total stock) with limited effort made until now. The results indicate that it is challenging to engage private investors in the early years, even using subsidies; thus, publicly financed infrastructure deployment is important for the first years. In the mid-term, subsidization on the costs of charging points is necessary to positively influence the uptake of private investments. These are mainly attracted from 2025 onwards, after a critical mass of EVs and infrastructure has been deployed.
