Electric Vehicle Positioning for Inductive Charging Purposes Using Magnetic Field Distortion Elimination in High-Permeability Environments
This paper presents a novel method to position electric vehicles for inductive charging purposes. The approach is to get position information by measuring the magnetic flux density caused by the charging coil located in the ground of the parking place.

| description | This paper presents a novel method to position electric vehicles for inductive charging purposes. The approach is to get position information by measuring the magnetic flux density caused by the charging coil located in the ground of the parking place. However, the sensors are mounted at the high-permeable undersurface of the vehicle, which leads to field distortions and, consequently, to high measurement errors. In this paper, these distortions were investigated by means of the finite-element method. Thereby, the vehicle was designed as finite expanded cuboid of high permeability. From these results, a simple mathematical model was derived, which maps the original field to the distorted one. In the following, this model and its validity constraints are discussed more in detail. |
