Abstract

This disclosure provides systems, methods and apparatus for assessing electromagnetic exposure. In one aspect an apparatus is provided. The apparatus includes at least a first circuit configured to calculate electromagnetic exposure of at least a portion of at least one human in proximity to a wireless electric vehicle charging system. The portion of the at least one human is modeled by at least one homogeneous phantom model having dielectric properties that are representative of human tissue. The apparatus further includes at least a second circuit configured to scale the calculated electromagnetic exposure to simulate an electromagnetic exposure based on an inhomogeneous anatomical model of the portion of the at least one human.

Description

technical field [0001] The present invention relates generally to wireless power transfer, and more particularly to devices related to wireless power transfer to remote systems (e.g., vehicles containing batteries) and assessing electromagnetic exposure from such wireless power transfer devices and systems, systems and methods. Background technique [0002] Remote systems, such as vehicles, have been introduced that incorporate electrically derived motion power received from an energy storage device, such as a battery. For example, a hybrid electric vehicle includes an on-board charger that uses power from the vehicle's brakes and a conventional electric motor to charge the vehicle. Purely electric vehicles generally receive electricity from other sources to charge the batteries. It is often proposed to charge battery electric vehicles (EVs) by some type of wired alternating current (AC), such as a household or commercial AC power source. A wired charging connection requi...
