Abstract In recent years, wireless power transfer has been widely applied. One of the main applications is electric vehicle charging. To effectively evaluate the safety of human body in the electric vehicle (EV) charging electromagnetic environment, 3D electromagnetic simulation software is used to build the electromagnetic environment of the electric vehicle charging model. Accordingly, the electromagnetic exposure problems of the main tissues are studied. The results show that different tissues in human body have different absorption of electromagnetic waves because of their different electromagnetic parameters. Herein, the maximum current density is 20.058mA·m^-2, the maximum power density is 1.22×10^-5W·m^-2, and the maximum SAR value is 4.37×10^-7W·kg^-1, which are all below the safety limits of ICNIRP guidelines. It is shown that the human body in the electromagnetic environment is basically safe.

Key words： Wireless power transfer, electric vehicle (EV), human body, electromagnetic environment
