Abstract

Overview

This study presents a quantitative analysis of the electromagnetic exposure dose of a pure electric vehicle inverter to the driver’s body using a model based on real human anatomy. The research assesses the safety levels of electromagnetic exposure considering various internal organs and tissue simulations.

Methodology

• A sophisticated human model with different organs and tissues was used.
• The primary electromagnetic source in this study was the inverter of a pure electric vehicle.
• The study utilized an equivalent electromagnetic environment model comprising a real human body, an inverter, and the vehicle body.
• The finite element method was applied to calculate the induced fields in the driver's tissues and organs.

Findings

Results indicated that electromagnetic fields' impact varied based on spatial distances from the source inverter. Tissue dielectric properties affected the distribution of the induced fields significantly. Although field measures near the inverter exceeded ICNIRP safety levels, the overall exposure for the driver met safe levels decreasing with distance.

Conclusion

While immediate proximity to the inverter shows elevated levels of electromagnetic fields, the safety levels are adequate at the driver’s position. The environmental electromagnetic conditions at this distance are within international safety guidelines, confirming that the electromagnetic design is safe for drivers. This contributes positively towards setting industry standards and designing safer electric vehicles concerning electromagnetic exposure.
