Pre-study: Test methods for conducted and radiated electromagnetic interference from charging
The electrification of transport causes installations of charging of batteries. They can disturb electromagnetically other devices. This pre-study comprises a literature review, measurements, and contact with various stakeholders.
Charging installations related to the electrification of transport are a source of conducted and radiated electromagnetic disturbances. Development of test methods is needed to better understand these emissions and develop reasonable limits in order not to disturb the electromagnetic environment. Installations to be covered are rapid charging of electrified vehicles such as passenger cars, charging of large vehicles such as buses, trucks, battery trains, boats, and airplanes as well as the supply to electric roads.
The problem will be studied based on the following aspects:
- disturbances from the Swedish Transport Administration's facilities that affect the electromagnetic environment for others
- disturbances in the electromagnetic environment affecting the Swedish Transport Administration's facilities as well as
- disturbances within the Swedish Transport Administration's facilities.
During the pre-study, the severity of the disturbances will be assessed through literature study, empirical experience, measurements, and contact with various stakeholders. The feasibility study is expected to result in a detailed description of the content for the project.
During the pre-study, an initial survey will be made to explore methods for measuring the emission and to create an inventory of possible consequences.
