City of Rüsselsheim am Main is making a big leap forward in expanding its charging infrastructure for electric vehicles. On Wednesday (September 8th), Mayor Udo Bausch and Opel HR Director Ralph Wangemann put the first of three public charging farms with 152 charging points into operation. The charging farm was set up on a now public parking lot in front of the Opel factory gate. In the future, citizens and factory employees should be able to use the area on Mainzer Straße to charge their electric vehicles.

“Today is an important day for Rüsselsheim. As a city, we are keeping a first part of the promise we made to the citizens of Rüsselsheim: That Rüsselsheim will become electric, ”explained Mayor Udo Bausch. For this, he thanked the federal government as the sponsor, all partners and service providers of the project, in particular the Rüsselsheim municipal utilities, who took care of the network expansion, and Opel, who made space available. "Formerly private, company-owned employee parking spaces have now become public parking spaces that are also accessible to the general public."

"Together with the project partners, the city of Rüsselsheim has created this infrastructure in our hometown and thus not only ensures that Rüsselsheim remains a" car city ", but that Rüsselsheim will be a" car city "of the future," said Opel - Managing Director and Labor Director Ralph Wangemann. "I would like to express my thanks to everyone who made this project possible."

Charge electricity with up to 22 kilowatts

Rüsselsheim charging farm is charged at normal charging points with alternating current (AC) and a charging capacity of up to 22 kilowatts. The charging time is between two and four hours, depending on the charging capacity of the charging station, the capacity of the battery and the charging technology of the electric car. Type 2 charging sockets are located at all charging points created as part of the Electric City project. This socket meets the requirements of AC charging in Europe and is installed in every modern electric vehicle.

Electricity with and without a contract

Anyone who would like to charge at one of the public Rüsselsheim Electric City charging stations has a wide range of tariff and contract options. Since the charging stations will in future be operated by the Rüsselsheim municipal utility, the municipal utility's green electricity is available for spontaneous charging without a contractual obligation (ad hoc charging). Anyone who is tied to the electricity of the municipal utility for at least three months can save money with the “ÖkoStrom Mobil” tariff compared to spontaneous charging and can also refuel at any charging station outside of Rüsselsheim that is part of the roaming network of ladenetz.de. Roaming partner can also charge any electricity from any third-party electricity provider at an Electric City charging station that is part of the Ladenetz.de cooperation network.

Two more loading farms are about to go into operation

By the end of October, the city will have opened a total of three charging farms with 540 publicly accessible charging points in parking lots in the city area. Up to 250 additional public charging points, spread across the entire city area, will follow successively in the coming weeks and months. With the Electric City project, a total of around 1,200 charging points will be created in Rüsselsheim by spring 2022: around 800 public and almost 400 private ones. Based on 67,000 inhabitants, this means a charging station density of one public charging point for every 84 citizens. “Projects like 'Electric City Rüsselsheim' are lighthouses that create an important basis for the mobility of the future. With the development of a future-proof charging infrastructure, we support our climate protection goals sustainably and clearly. And at the same time we support the Rüsselsheim-based economy in developing and establishing e-mobility, ”emphasized Mayor Bausch.

Activation via RFID card, app and QR code

So that the electricity can then be assigned to the right customer and correctly billed, the city of Rüsselsheim has up to four different ways of authenticating yourself for a charging process. City of Rüsselsheim relies on all current standards, but also on standards that are still in development.

First of all, there is the charging card, which activates the charging point for charging by simply stopping at the RFID field of the charging station. Greatest advantage of RFID cards is that they are easy to use. Municipal utilities will also use it to equip their electricity customers.

Smartphone apps of the various charging tariff and roaming providers offer a lot of additional information, such as the current occupancy of charging stations or the tariff. In Rüsselsheim, this can be done using the popular app from ladenetz.de. An existing internet connection is required for this.

Ad hoc charging, which does not require a contract, is also dependent on the Internet. For this, the customer data and a means of payment must be stored on the website of the electricity provider before loading. Website can be accessed via a QR code attached to the charging station, which is scanned with the smartphone camera.

A fourth, but still future, variant will be the “Plug & Charge”. Billing chips are integrated directly into the charging electronics of the electric vehicles, so that it will be possible to pay without cards, apps or QR codes. This form of authentication is currently still in development and, when it is ready for the market, will be installed as an update on the Electric City charging stations.
