Effect of wireless charging of mobility scooters on human health and temperature increase of their chassis

Abstract

In his paper, the authors study the effect of a static wireless charging system designed for a mobility scooter. The increase in the temperature of the scooter chassis and the impact of the system's magnetic field leakage on human health are presented in this paper. A model under the Finite Element Method software COMSOL multi-physics has been realized. The magnetic field and heat transfer physics are simulated to study the elevation of the scooter’s chassis temperature due to exposure to the magnetic field generated by the wireless charging system. The magnetic flux streamlines and its density near the human body are also presented in this paper and compared to the guidelines limit fixed by the International Commission on Non-Ionizing Radiation Protection. Furthermore, an overview of the concept of inductive resonant transfer and the necessity of shielding the wireless charging system is presented in this paper. Results show a low increase in temperature of the chassis and no significant effect on human health compared to the guidelines norms.
