A smart charging profile was implemented on 39 public charging stations in Amsterdam on which the current level available for electric vehicle (EV) charging was limited during peak hours on the electricity grid (07:00-08:30 and 17:00-20:00) and was increased during the rest of the day. The impact of this profile was measured on three indicators: average charging power, amount of transferred energy and share of positively and negatively affected sessions. The results are distinguished for different categories of electric vehicles with different charging characteristics (number of phases and maximum current). The results depend heavily on this categorisation and are a realistic measurement of the impact of smart charging under real world conditions. The average charging power increased as a result of the new profile and a reduction in the amount of transferred energy was detected during the evening hours, causing outstanding demand which was solved at an accelerated rate after limitations were lifted. For the whole population, 4% of the sessions were positively affected (charged a larger volume of energy) and 5% were negatively affected. These numbers are dominated by the large share of plug-in hybrid electric vehicles (PHEVs) in Amsterdam which are technically not able to profit from the higher current levels. For new generation electric vehicles, 14% of the sessions were positively affected and the percentage of negatively affected sessions was 5%.
Many, many comparisons have been drawn in recent years between the current rise of (right-wing) populism and the financial crisis of 2008 that shook and continues to shake Europe to its core, and the tumultuous and horrifying events of the 1930s, which in the end resulted in the Second World War. A number of recent studies which (partially) focus on this decade carry ominous titles like To Hell and Back, The Age of Catastrophe and The Triumph of the Dark. Referred to by some historians as the second Thirty Years’ War, the period from the First World War to the end of the Second still continues to draw much academic and indeed public attention. In many cases, Germany deservedly plays a central role in the analysis, either in the form of the Kaiserreich or the ill-fated Weimar Republic and, of course, Nazi Germany. The five books under review here discuss European history between 1914 and 1950 in general, and that of Germany in particular, in this period. What do these books tell us about Europe’s and Germany’s path in the first half of the twentieth century, and what new insights do they provide? https://doi.org/10.1177/0265691418777981 LinkedIn: https://www.linkedin.com/in/martijn-lak-71793013/

this thesis was simply a research done to see how the manor amsterdam can use technologies to enhance its guest eperience. Surveys and intervews were conducted to see what the guest preferences were after which an implementation process was also drawn up.
