Amsterdam is preparing together with Nuon, Liander and ElaadNL for an expected increase of electric cars in the city and the use of more locally generated renewable energy. Thus, on March 1, 2017, Amsterdam began with 'flexible charging' of electric cars: tuning electric cars to match supply and demand of sustainable power.
We want to gain insight and experience with possible new forms of contracts for a variable capacity network connection, which are also interesting to market parties and submitted (or tested by) the legislative authorities.Therefore, at public charge points operated by Nuon in Amsterdam, we are going to test the so-called flexible charging.
The design of the current electricity grid has not taken into account the arrival of electric cars. More electric cars mean an increasing demand for power. Therefore, it is necessary to test which product features the future electricity grid must meet.
We are going to adjust the charging speed to the pressure on the electricity grid. Two hundred charge points match the charging of electric cars to the total demand and supply of sustainable power. In this test, electric cars are automatically charged with more power throughout the whole day. This means they will be charged faster than normal at this time of the day. Only during peak hours (between 16.30 and 19.30), when other devices (such as devices in households) demand a lot of power, the cars are charged slower and with less power. With this method more e-drivers can use the same charge point and less public charge points are needed. By monitoring the charging data, charging cars are always full enough for the next trip during the pilot.
The pilot begins with two hundred public charge stations with two sockets each in the center, the West, New West and South of Amsterdam. Analysis has shown that the highest power rates and most kWh are loaded here. Based on historical data, it is expected that more than 1,000 to 1,500 unique users will charge their car at these charge points.
The research started on March 1, 2017 and lasts until 31 December 2017.
Partners in this project are the City of Amsterdam, Nuon&Heijmans, Liander and ElaadNL.
