Abstract

Overview

The rapid increase in electric vehicles (EVs) has led to a corresponding rise in the number of EV charging stations. This study extensively evaluates the electromagnetic field (EMF) exposure levels from six different EV chargers.

Methodology

Researchers measured and analyzed EMF emissions from six distinct EV chargers to determine exposure levels. These were compared against the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines to assess compliance with safety standards.

Findings

• Standard chargers exhibited higher electromagnetic fields compared with fast chargers.
• The magnetic field for a fast charger increased with the charging current, indicating a potential variable risk factor.
• None of the measured EMF levels exceeded the ICNIRP guidelines, suggesting the adherence to current safety standards.

Conclusion

This research highlights the variations in EMF exposure across different types of EV chargers and underscores the crucial need for continued evaluation and standard-setting in this growing field. The maximum EMF values observed with changes in the state of charge (SoC) suggests further investigation on how EMF levels fluctuate with charger usage is essential for ensuring public health and safety.
