Long-Term Monitoring of Extremely Low Frequency Magnetic Fields in Electric Vehicles

Abstract

Overview

The exposure to extremely low frequency (ELF) magnetic fields (MF) in electric vehicles (EVs) poses notable health concerns. Continuous monitoring and assessment of these fields are critical to understanding their health implications.

Findings

• This pioneering study conducted a two-year monitoring of magnetic flux density (B) within three different shared EVs.
• Assessments were made both at the front and rear seats during periods of acceleration and constant-speed driving.
• The study discovered that alterations in the vehicle's components and hubs could modify the accompanying B amplitudes and spectral elements.
• Interestingly, routine checks or maintenance appeared to have no impact on the B values.

Conclusion

The findings underscore the importance of systematic monitoring of ELF magnetic fields in EVs, particularly following significant repairs or accidents, to shield occupants from potential overexposures. Such considerations should be incorporated into updated measurement standards and taken into account in related epidemiological research.
