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 of the policies, with a special focus on the actual reduction of emissions. Consequently the number of public charging stations also rose. The chapter provides an analysis of how these charging stations are used and in which way this is related to sales policies. The chapter provides several lessons learned on how to shape policy to get a group of early adopters to drive electric.

In een hybride virtueel klaslokaal (HVC) zijn docenten en/of studenten zowel fysiek als digitaal synchroon bij een onderwijsonderdeel aanwezig. De online studenten danwel docenten kunnen thuis zijn, of bevinden zich bijvoorbeeld in een authentiek werksituatie of ergens in het buitenland. Hybride virtuele klaslokalen zijn ontworpen om studenten op locatie en studenten op afstand aan elkaar te verbinden. De fysieke en digitale onderwijsactiviteiten lopen synchroon aan elkaar. Het kan daarmee ook digitaal aanschuifonderwijs genoemd worden. Wat zijn de voordelen van het HVC? Wanneer gebruik je het en wanneer gebruik je het niet? Op welke manier gebruik je het dan en welke consequenties heeft dit voor het didactische repertoire? Welke technische opstellingen horen hierbij? Het lectoraat Teaching Learning & Technology heeft onderzoek gedaan naar de inzet van HVC in het onderwijs en vanuit interviews met docenten en ondersteuners praktische handvaten ontwikkeld op zowel didactisch als technisch niveau. Deze zijn te lezen in het onderzoeksrapport.

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%.
