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

Abstract

Overview

The popularity of pure electric vehicles (PEVs) is steadily rising as society pivots towards renewable energy sources and sustainable transportation options. However, there is a growing concern regarding the electromagnetic environments created within these vehicles, particularly from inverter systems that are crucial for power conversion and generate strong local electromagnetic fields.

Methodology

• Researchers constructed an electromagnetic environment model of the PEV body, human body, and a simplified inverter.
• Finite element analysis, using COMSOL Multiphysics software, facilitated the calculation and examination of electromagnetic induction field variations within different tissues of both the driver and rear passenger.
• Exposure levels were specifically analyzed under maximum power operation of the inverter system.

Findings

• Results reveal notable differences in electromagnetic exposure levels depending on seating position.
• The driver’s body is exposed to higher electromagnetic fields compared to the rear passenger.
• Despite these elevated exposure levels, measurements did not exceed the thresholds set by the International Commission for Non-ionizing Radiation Protection (ICNIRP).

Conclusion

This study highlights the importance of evaluating electromagnetic safety within electric vehicles, reinforcing the connection between EMF exposure and potential health effects. The findings enhance public awareness and contribute valuable data to the assessment and regulation of EMF safety standards. It is vital to remain alert to the health implications associated with prolonged electromagnetic field exposure from vehicle inverters, even when current exposure limits are not surpassed.
