iTOKEN aims to reduce transaction costs for charging electric vehicles using blockchain technology. Anyone charging their electric vehicle at a particular charging station from a charge point operator without that particular subscription, usually pays an additional fee. These “roaming” fees become very costly for e-mobilists both, financially and by inhibiting a seamless charging experience. The fees are created because the charging station operators with various electromobility providers, who are responsible for the payment and handling of charging processes, use different systems. Our project set out to reduce transaction costs for charging electric vehicles using blockchain technology. This would make it possible to reduce roaming costs in electric mobility in the future. More efficient payment processes are available thanks to Blockchain technology. With this project, iTOKEN offered a Blockchain application for charging processes utilizing.
