Abstract

Evaluation of electromagnetic fields in human body exposed to inverter of pure electric vehicle Dong X, Sun W, Lu M. Evaluation of electromagnetic fields in human body exposed to inverter of pure electric vehicle. Radiat Prot Dosimetry. 2022 Dec 22:ncac269. doi: 10.1093/rpd/ncac269. Abstract On the basis of the basic principle of electromagnetic dosimetry, the paper studies the electromagnetic exposure of a passenger's body to a compound electromagnetic field caused by the combined action of DC and AC bus currents of a pure electric vehicle inverter. By building an electromagnetic model of a pure electric vehicle body, adult human body and inverter, the finite element method is used to calculate the magnetic induction intensity(|B|), induced electric field intensity(|E|) and induced current density(|J|) of the compound electromagnetic field to the human trunk and central nervous system in the driver and front seat passenger. The numerical results are compared with the exposure limits defined by the International Commission on Non- Ionizing Radiation Protection (ICNIRP). The fields are well below the safe exposure limits defined by ICNIRP. pubmed.ncbi.nlm.nih.gov

Main findings

Using finite element modeling of a pure electric vehicle body, adult human body, and inverter, the study calculated |B|, |E|, and |J| in the human trunk and central nervous system for the driver and front-seat passenger. The calculated fields were reported to be well below ICNIRP exposure limits.

Outcomes measured

  • magnetic induction intensity (|B|)
  • induced electric field intensity (|E|)
  • induced current density (|J|)
  • comparison to ICNIRP exposure limits

Limitations

  • No specific frequencies, field magnitudes, or quantitative results are provided in the abstract.
  • Modeling study (finite element method) rather than direct measurements in humans is described in the abstract.
  • Exposure duration/conditions are not described in the abstract.
