Interference-free charging of electric aircraft

Published: 26 November 2021

Can a charging station for electric aircrafts affect other electrical equipment at an airport? Researchers at Luleå University of Technology will find out. The investigation is part of a project that aims to set up an airstrip for a battery electric powered commuter aviation, between Skellefteå Airport and Northvolt battery factory.

The airstrip is about 25 kilometers. By car, the journey takes half an hour, with an electric commuter aviation eight minutes. For the journey, a so-called eVTOL aircraft will be used, ie an electric aircraft that takes off and lands vertically. To "refuel" the aircraft, charging stations intended for electrified aviation will be needed, they contain powerful electronics and high voltage. There are regulations and limit values ​​for how the electromagnetic radiation from electronic devices may interfere with other surrounding technology and equipment. In the project, the researchers at Luleå University of Technology will find out how this electromagnetic interference, EMI, works in relation to an airport.

– We will map the regulations that exist in order to be able to set requirements for this type of installation. Through measurements, simulations and modeling, we also hope to be able to create an overall picture of the challenges that EMI creates in the airport environment, says Jonny Johansson, professor of electronics systems at Luleå University of Technology.

– Our work contributes to the safety work that surrounds the aviation world in which we now see a forthcoming large increase in electrified aircrafts.

Green development

Luleå University of Technology has years of research experience in the field of EMI and EMC, electromagnetic compatibility. According to Jonny Johansson, the research’s link to the green transition in Västerbotten and Norrbotten is both inspiring and developing.

– Electrification opens up for questions about electrical engineering and its applications, drive systems and how to manage batteries just to name a few examples. New companies are establishing in our region, it gives us the opportunity to find new partners and interesting projects.
