“…The utilization rate-specifically, the energy-based utilization rate-can be defined as the ratio of the actual energy delivered and the theorical energy which could be delivered if the station was fully exploited at its nominal power [37]. This parameter is influenced by several factors: first and foremost, by the amount of time for which EVs are plugged to the recharging point, but also by the extent of idle periods (idle times are those periods in which a vehicle is plugged to the recharging point, but not charging; for instance, when the vehicle is left plugged at the recharging station after the completion of the charging cycle) and by the effective power delivered to the vehicle [38,39]. The latter can differ from the nominal power of the recharging point, depending on the charging strategy (e.g., demand-driven or smart-charging), the state-of-charge of the battery, and the power acceptance of the EV [39].…”

The electrification of transport is expected to progressively replace significant shares of light duty mobility, especially in large cities. The European Alternative Fuel Infrastructure Regulation (AFIR) aims to drive the adoption of electric mobility by establishing specific targets for charging point deployment. Innovative charging concepts may complement and accelerate the uptake of this fundamental part of the urban mobility transition. In this paper, one such innovative concept is described and its potential impact is assessed. The core idea involves integrating charging points into existing city tramway infrastructures. Turin’s tramway network is taken as a representative case study. The proposed technical solution encompasses a charging hub powered by four isolated DC/DC converters of 50 kW, directly connected to the DC tramway distribution line. Three of these constitute the heart of a 150 kW charger, while the fourth acts as voltage regulator. This native DC installation greatly simplifies the architecture of the DC chargers. Using a conservative approach, it was estimated that a single recharging station could charge more than 60 vehicles daily. This highly scalable and replicable solution, with the potential for over 100 conversion substations across Italy, would enable the installation of numerous high-power chargers in urban settings. Furthermore, additional benefits could be realized through enhanced recovery of kinetic energy from trams, which is currently dissipated on-board.

“…These studies [18][19][20][21][22][23] provide insight into what factors should be analyzed to predict the amount of charging energy required at EV charging stations, but they do not optimize for the actual location of EV charging stations. Therefore, a review of previous studies analyzing the location of EV charging stations was conducted to prioritize the installation of EV charging stations.…”

“…Many socioeconomic factors play a role, so it is important to determine which ones should be analyzed to prioritize the location of EV charging stations. This study examined the key factors, including the population (population within a radius of approximately 914 m) ( [18,22,23], [30], [32][33][34][35], [37]), the number of registered EVs ( [18,22], [19,20], [32,33], [36]), traffic volume ( [23], [30], [31], [37]), and land value, which can approximate income level (land value within a radius of approximately 914 m) ( [18], [19][20][21], [30], [32], [37]).…”

The demand for electric vehicles is increasing due to the recent focus on reducing greenhouse gas emissions. Hence, the number of electric-vehicle charging stations must be increased to meet the growing demand for electric vehicles. To this end, supportive policies are being established to increase the deployment of electric vehicle charging stations worldwide. On the other hand, it is not possible to subsidize all facilities simultaneously. This study developed a model to prioritize the deployment of electric vehicle charging stations. The Republic of Korea was analyzed as a case study region to develop this model, and the correlations between the amount of charging energy of electric vehicle charging stations and socioeconomic factors (traffic volume, population, number of electric vehicles, and land value) were analyzed. The correlations were analyzed differently depending on the purpose (e.g., residential or commercial) of the facilities where electric vehicle charging stations were installed. Correlation analysis was conducted to determine the factors that affect the amount of charging energy, and a model was developed to prioritize the deployment of electric vehicle charging stations through a genetic algorithm. A model with a correlation of more than 0.2 was developed, except for residential facilities with slow chargers and public institutions with slow chargers. The results of this paper can help identify the key factors to be analyzed by facility use when installing electric vehicle charging stations and determine the priorities for subsidizing the deployment of electric vehicle charging stations.

“…Authorities can also regulate the time vehicles can spend parked in charging points to reduce idle time and increase their use rate. Vehicle electrification and public charging will increase the use of street space for parking, as vehicles stay parked in public charging spaces longer than their charging needs require (Borlaug et al, 2023;. As technology and economies of scale evolve, faster on-street public chargers will likely be deployed, making this difference between parking and charging times even higher.…”
