Smart charging plaza Oude Veerseweg Middelburg as part of the project ‘Proeftuin Slimme Laadpleinen’

Deze pagina in het Nederlands Project Middelburg

Welcome to the project page of our smart charging plaza located at the Oude Veerseweg in Middelburg. This charging plaza is part of a national project called “Proeftuin Slimme Laadpleinen”. A project in collaboration with several partners and partly subsidized by the Dutch government. The purpose of this project is to gain experience and acquire knowledge of smart charging concepts and specifically vehicle-to-grid charging. Here you will find practical information about the charging plaza and what makes our charging stations smart. Additionally, you will find the research questions of the project and, in time, the answers to these questions.

Project background “Proeftuin Slimme Laadpleinen”

In the Netherlands we face a major challenge in the change towards sustainable mobility. The ambition of the Dutch government is that in 2030 all newly sold cars are zero emission. With this ambition comes a need for 1,7 million charging stations for electric vehicles in the Netherlands. Charging plazas, which are a concentration of charging stations, can be a quick and efficient way to meet the demand for charging stations. Additionally, this concentration of charging stations and electric vehicles provide opportunities for a sustainable energy system in which we use the batteries of these vehicles to temporarily store green energy. The goal of this project is to gain and share knowledge while thus contributing to a balanced power grid and additional charging infrastructure in the Netherlands.

What is smart about this charging plaza

Differentiation in charging power

Depending on the duration of your stay and type of electric vehicle you can choose between 2 charging powers with matching tariffs: Smooth and Power. Smooth charging points are best when you have more time to charge you electric vehicle. For example during the (work)day or at night. Power charging points are suitable for vehicles that can charge 3-phases and with a short duration. By choosing the appropriate charging power the electric driver decreases the price of the charging transaction and we do not unnecessarily overload the power grid.

Connection tariff

With the rapid increase of electric vehicles there is a great need for charging stations. To increase the availability of charging stations we charge a tariff per hour as well. With this tariff we stimulate electric drivers to not occupy the charging station unnecessarily. When you charge socially you benefit from a lower price.

Social Charging

We also use software to increase the availability of our charging stations. With the free Social Charging application you can queue for a charging station and (anonymously) chat with other electric drivers. For example to propose to change parking spots.

Load balancing

The charging station divides the available power as efficient as possible between the charging vehicles. Taking into account also the charging power of the electric vehicle and if it can charge single phase or 3-phases. Load balancing is the reason why at public charging stations you charge faster when there are less other vehicles charging at the same time.

Future applications of smart charging

Bi-directional charging

Our charging stations are prepared for bi-directional charging, also known as Vehicle-to-Grid (V2G). This means that, when the electric vehicle is able to, the electric vehicle cannot only take electricity from the power grid but it can also deliver electricity back to the power grid. With this technology it becomes possible to integrate electric vehicles in a sustainable energy system. While parked, an electric vehicle can store green energy, that can be used when there is insufficient green energy available.

Smarter Charging

With smart algorithms the charging power and starting time of a charging session can be adjusted. This makes it possible to increase the charging power when the availability of green energy is high. When there is little cheap and green energy available, charging power decreases. Of course always taking into account that the electric driver has enough energy for an unplanned trip. Applying these technologies enables us to decrease our carbon dioxide emissions even further, spares the power grid and is cheaper.

Research questions project Smart Charging Plaza Oude Veerseweg Middelburg

  1. What is the effect of a connection tariff on the availability of charging stations in Middelburg?
  2. What is the effect of the application Social Charging on the availability of charging stations?
  3. What is the impact of this charging plaza on the power grid and how can vehicle-to-grid charging be used to relieve the disbalance?
  4. What is the seasonal impact of summer on this charging plaza? And what are appropriate solutions to meet this variable demand?
