Abstract

Overview

The purpose of this study is to quantitatively analyze the electromagnetic exposure levels to the driver’s body from an inverter in a pure electric vehicle and to ensure its safety standards.

Methodology

• Uses a real human anatomy model within the virtual home project framework, incorporating various organs and tissues like muscles, bones, heart, and CNS.
• An equivalent electromagnetic environment model was developed combining a real human body, an inverter, and a vehicle body.
• Finite element method was employed to calculate and analyze the induced fields within the driver’s tissues and organs.

Findings

Induced electromagnetic fields’ intensity within the driver’s body varies with distance from the inverter source, with weaker intensities at greater distances. Different tissues exhibited varied responses due to differing dielectric properties.

Conclusion

The study confirms that the electromagnetic fields from the inverter are within safe exposure limits as per the International Commission on Non-Ionization Radiation Protection (ICNIRP) standards. The designed electromagnetic conditions of the inverter are safe for the driver’s health in its operating state.

Furthermore, the findings provide valuable data that could help in setting industrial standards and designing safer electric vehicles concerning electromagnetic exposure.
