Study on the safety assessment and protection design of human exposure to low-frequency magnetic fields in electric vehicles.

This article focuses on assessing low-frequency magnetic field exposure and safety within electric vehicle cabins. It presents a combined simulation and experimental study analyzing magnetic flux density, induced electric field strength, and induced current density in human occupants, demonstrating that measured and simulated values remain well below the limits set by the Chinese national standard GB8702-2014 and the International Commission on Non-Ionizing Radiation Protection (ICNIRP). The study identifies the vehicle’s power cables as the primary source of low-frequency electromagnetic fields, with exposure levels varying by driving conditions, body position, vehicle body materials, and cable layout. Findings suggest aluminum alloy vehicle bodies and cable placements away from occupants reduce magnetic field exposure, providing guidance for safer electric vehicle design and human electromagnetic exposure protection.
