Abstract

Overview

This document aims to establish standardized assessment methods for evaluating whether stationary and dynamic wireless power transfer (WPT) systems comply with guidelines regarding human exposure to electromagnetic fields. These guidelines cover limits for specific absorption rate (SAR), internal electric fields, and current density, including situations involving contact currents.

Scope

  • Focuses on a frequency range from 1 kHz to 30 MHz.
  • Emphasizes exposures from inductive wireless power transfer systems, with future expansions expected for capacitive systems.
  • Provides detailed models, instrumentation, measurement techniques, and numerical methods to ensure comprehensive exposure assessment.

Findings

The draft standard outlines technical procedures to guarantee that electromagnetic exposure, resulting from stationary or dynamic operation of WPT systems, does not exceed established safety benchmarks. These procedures protect human health by ensuring that limits for electromagnetic field exposure, such as SAR, are not breached.

Conclusion

Following the specified assessment methods is crucial to support compliance with electromagnetic field safety guidelines. The document helps ensure that WPT systems are safe to use and that potential health risks arising from electromagnetic field exposure are properly controlled, recognizing the established connection between EMF exposure and possible health effects.
