Assessment of Low-Frequency Magnetic Fields Emitted by DC Fast Charging Columns
Abstract
Overview
The rise of electromobility in transport systems necessitates a deeper understanding of the potential human health impacts from exposure to magnetic fields during electric vehicle use and charging.
Findings
- Increase in electric vehicle battery capacity and charging power leads to higher currents and potentially stronger magnetic fields.
- Focused experimental activity by the Interoperability Center of the Joint Research Center assessed magnetic fields emitted by five market-leading fast-charging devices.
- Study aimed to refine standard measurement procedures for evaluating magnetic fields from direct current charging columns.
- Identified worst-case scenarios included significant magnetic field measurements with local flux density peaks exceeding 100 μT at the 50 Hz frequency.
Conclusion
Local peaks considerably above health safety reference levels demonstrate a need for ongoing monitoring and regulation to protect both general and occupational populations during vehicle charging.
