IOTA: Proof of concept for charging stations for e-cars

iota ecars

In April this year, ElaadNL presented the world’s first charging station for electric cars in the Netherlands, making charging and payments with IOTA possible. After nearly five months of testing, the developers have a positive interim balance, as reported by Invade.

The test site for the charging station, ElaadNL, was officially opened by the Dutch State Secretary for Infrastructure and Water, Stientje van Veldhoven on April 18. In addition to the IOTA charging station, it can be used for other types of charging stations.

The IOTA charging station is a proof of concept to test how the IOTA Distributed Ledger Technology can be used specifically for the machine-to-machine interactions in the field of electric cars. This includes secure data transfer and real-time micropayments.

The following video (from April) shows the charging station for e-cars, which is completely based on IOTA. Vehicles can connect to the charging station to charge the car battery. The car practically pays for itself. The costs of the refueling process in IOTA and everything else runs completely autonomously. So far, however, the proof of concept for regular e-cars is not ready to use, because it requires specific hardware.

Strategic Partnership Between IOTA and InnoEnergy

The IOTA Foundation and InnoEnergy Scandinavia signed a Memorandum of Understanding to work together for researching the development of e-mobility and smart contracts in the energy sector. The collaboration resulted from the successful participation of InnoEnergy in the IOTA Data Marketplace in November 2017.

Harm van den Brink, expert for IT architect Smart Grids & Distributed Ledger Technology at ElaadNL, said to Invade

“No back office and no communication protocol are required to operate the charging station; the transactions are exchanged directly without the use of a charge card or subscription,”

Counter readings are stored in the Tangle every 15 minutes, ensuring reliable and irrefutable management. Van den Brink told Invade:

“The charge station has been tested multiple times with the special hardware (mini-Tesla) we built. We are currently busy implementing a QR-code display, so everybody can directly pay and charge.”

After nearly five months of testing, the next goal is to integrate the charging station into a smart network of machines that IOTA uses to distribute information, such as information on capacity utilization. In addition, the devices should be able to send their energy consumption to Tangle:

“The transformer can ask connected devices to do smart charging, and if they listen to that they will get incentivized directly by sending them IOTA tokens. This will also be a proof of concept, and we expect results by the end of this year.”
