Challenge / Goal

The municipality of Cologne aims to promote the replacement of fossil fuelled vehicles with more sustainable alternatives. A good charging infrastructure is the prerequisite for a better integration of E-mobility.


In the district of Mülheim, new charging infrastructure was setup, which enables the tenants to charge their electric vehicles. Customers are required to register at tankE ( to use the charging stations. To start or stop the charging process users have to send a text message via mobile phone. The only costs at this point are the cost of an ordinary text, which depends on users’ choice of mobile phone contract.

As a registered driver, you are able to fill your vehicle at “Tanke” branded charging stations with green electricity from renewable sources. The charging time depends on the vehicle type. The Renault Zoe, for example, needs 1hour to be fully charged, but other types could take longer. During the introductory period, charging is provided free of charge.

Additionally to encourage use of Electric vehicles, in cooperation with KVB, the car-sharing company Cambio and the carpark-sharing company Ampido, tenants are offered various forms of shared e-mobility options. This offer renders the use of a private car unnecessary. Customers need to register on tankE website to use the charging station.
