Bosch, EnBW and Siemens have jointly developed a Proof of Concept that makes the future of the EoT tangible: A Bosch-modified e-car communicates via blockchain with a Siemens traffic light to gain access to a site and then with an EnBW charging pole for the loading process. The transactions required for identification, authorization and payment are processed autonomously on a blockchain via a Smart Contract, which contains the contract conditions for the vehicle, traffic light and charging station. A technological milestone that was only possible thanks to the proactive, open and cooperative approach of the three partners. "It took less than three months from idea to implementation. This speed could become a success factor in in setting up an EoT," says Christian Heise, deputy project director EoT at Bosch.
