Electromagnetic exposure level of pure electric vehicle inverter to human body in different seating positions

Abstract

Overview

The growing market share of pure electric vehicles (PEV) as a means of green transportation closely aligns with the expanding global demand for renewable energy and environmentally friendly mobility. In this context, understanding the electromagnetic exposure levels caused by PEV components is crucial.

Methodology

This study establishes an electromagnetic environment model involving the PEV body, the human body, and a simplified inverter. Using the finite element software COMSOL Multiphysics, the research analyzes how the electromagnetic fields generated by the inverter system at maximum power affect different tissues in the driver and rear passenger.

Findings

• The study reveals significant differences in electromagnetic exposure levels depending on the seating position within the vehicle.
• Drivers experience higher electromagnetic exposure compared to rear passengers; however, the levels remain within safe limits as defined by the International Commission for Non-ionizing Radiation Protection.

Conclusion

The findings contribute valuable insights into the safety evaluations of electromagnetic environments in PEVs, enhancing public awareness and informing future safety protocols.
