Magnetic Field Effects on Human Body of Wireless Chargers for E-bikes

摘要

For the electric vehicles battery charging, the wireless power transmission is increasingly representing an innovative solution. The inductive power transfer is the standard technology of wireless charging: the energy transfer occurs between two magnetically coupled coils. Although this battery charging system is especially convenient for E-bikes, the physiological effects of the related magnetic fields shall be estimated and taken into account. In this paper, a 200 W prototype of wireless battery charger for E-bikes is proposed and described. Moreover, various measurements of the surrounding magnetic field are carried out to evaluate the actual physiological compatibility of the system.
