Charging infrastructure deployment has taken off in many cities with the rise of the number of electric vehicles on the road. Expansion of infrastructure is a matter of prioritisation of resources to optimise the infrastructure. This paper explores how to measure charging station performance, to address the challenges that policy makers face. These...
The ever-increasing electrification of society has been a cause of utility grid issues in many regions around the world. With the increased adoption of electric vehicles (EVs) in the Netherlands, many new charge points (CPs) are required. A common installation practice of CPs is to group multiple CPs together on a single grid connection, the so-cal...
Executive Summary This study used historical data from a Park & Ride facility in Amsterdam to build a validated computer (Python) model to optimize battery and grid connection sizing. The case study modelled is equipped with 8 EV chargers (16 connections), an on-site supplementary battery, and a limited capacity grid connection. This model was then...
During the COVID-19—related lockdowns (2020–2022), mobility patterns and charging needs were substantially affected. Policies such as work from home, lockdowns, and curfews reduced traffic and commuting significantly. This global pandemic may have also substantially changed mobility patterns on the long term and therefore the need for electric vehi...
Underutilised charging stations can be a bottleneck in the swift transition to electric mobility. This study is the first to research cooperative behaviour at public charging stations as a way to address improved usage of public charging stations. It does so by viewing public charging stations as a common-pool resource and explains cooperative beha...
Developments in battery technology have made it able to increase the range of electric vehicles without increasing the price. To combat range anxiety among potential customers OEMs are expected to keep adding range in the near future. It is expected that this also influences the charging needs of these future EV drivers. This paper analyses chargin...
The COVID-19 lockdowns showed that working from home and conducting meetings online can change mobility patterns and needs substantially. This global pandemic may have also substantially changed mobility patterns on the long-term and therefore, also the need of electric vehicle charging infrastructure. Charging need dropped significantly but also c...
A novel Smart Charging strategy, based on low base allowances per charger combined with 1. clustering of chargers on the same part of the grid and 2. dynamic non guaranteed allowance, is presented in this paper. This manner of Smart Charging will allow more than 3 times the amount of chargers to be installed in the existing grid, even when the grid...
On the eve of the large-scale introduction of electric vehicles, policy makers have to decide on how to organise a significant growth in charging infrastructure to meet demand. There is uncertainty about which charging deployment tactic to follow. The main issue is how many of charging stations, of which type, should be installed and where. Early r...
This paper explores current and potential future use of fast charging stations for electric passenger vehicles. The aim of the paper is to analyse current charging patterns at fast charging stations and the role of fast charging among different charging options. These patterns are explored along the lines of the technical capabilities of the vehicl...
Charging infrastructure development is vital for the adoption of electric vehicles (EVs). Yet, on the surface, there seems to be significant disagreement about when, how and which kind of charging infrastructure should be developed and most importantly, for what reasons. These reasons are concealed in the stakeholders’ perspective on the future. Di...
Charging station infrastructure is designed to meet the demand of electric vehicle (EV) drivers. Prediction of the necessary supply of charging stations is often a data driven process in which charging patterns from current EV drivers are used as an exemplar. These patterns are than extrapolated to estimate future demand. This is a stationary appro...
The Netherlands is considered one of the frontrunners in the field of electric mobility, both in number of plug-in electric vehicles sold as in the number of publicly available charging stations. This chapter analyses the policy measures that led to the growth in the number of plug-in hybrid electric vehicles. It also provides room for a critique o...
Early in 2012, our research team visited the policy-makers responsible for stimulating electric mobility in the city of Amsterdam. At the time, Amsterdam had recently installed several hundred public chargers, Car2Go was piloting with a small sharing program of electric smarts, and only a handful of (plugin) EVs were available on the market. Rather...
Fast charging is seen as a means to facilitate long-distance driving for electric vehicles (EVs). As a result, roll-out planning generally takes a corridor approach. However, with higher penetration of electric vehicles in urban areas, cities contemplate whether inner-city fast chargers can be an alternative for the growing amount of slow public ch...
Executive Summary Currently EVs constitute only 1% of all vehicles on the road. We are at the eve of the large scale introduction of EVs. Large scale introduction requires a significant growth in charging infrastructure. In an urban context, in which many rely on on-street charging facilities, policy makers deal with a large number of concerns. Pol...
With a growing number of electric vehicles (EVs) on the road and charging infrastructure investments lagging, occupation of installed charging stations is growing and available charging points for EV drivers are becoming scarce. Installing more charging infrastructure is problematic from both a public (tax payers money, parking availability) and pr...
Fast charging is usually seen as a means to facilitate long distance driving for electric vehicles and roll-out therefore often happens with corridors in mind. Due to limited charging speeds, EV drivers usually tend to charge at home or work when the car is parked for a longer period to avoid unnecessarily time loss. However with increasing chargin...
Recent studies show that charging stations are operated in an inefficient way. Due to the fact that electric vehicle (EV) drivers charge while they park, they tend to keep the charging station occupied while not charging. This prevents others from having access. This study is the first to investigate the effect of a pricing strategy to increase the...
This study is the first to systematically and quantitatively explore the factors that determine
the length of charging sessions at public charging stations for electric vehicles in urban areas, with
particular emphasis placed on the combined parking- and charging-related determinants of connection
times. We use a unique and large data set – contain...
Policy makers are looking for effective ways to promote the adoption of electric vehicles (EVs). Among the options is the roll-out and management of charging infrastructure to meet the EV drivers' refuelling needs. However, policies in this area do not only have a long-term effect on the adoption of EVs among prospective owners, they also have shor...
With the rise of the number of electric vehicles, the installment of public charging infrastructure is becoming more prominent. In urban areas in which EV users rely on on-street parking facilities, the demand for public charging stations is high. Cities take on the role of implementing public charging infrastructure and are looking for efficient r...
Since 2012 the dutch metropolitan area (the metropole region of amsterdam, the city of amsterdam, rotterdam, the hague, utrecht ) cooperate in finding the best way to stimulate electric mobility through the implementation of a public charging infrastructure. with more than 5600 charge points and 1.6 million charge sessions in the last two years thi...
