Method and apparatus for inductively charging the energy storage device of a vehicle by aligning the coils using heat sensors

摘要

A charging installation for inductively charging an electrical energy storage device of a vehicle, has a vehicle-side coil and a ground-side coil. At least one temperature sensor is disposed in the region of the ground-side coil and at least one heat source is disposed in the region of the vehicle-side coil.

主权项

1. A charging installation for inductively charging an electrical energy storage device of a vehicle, wherein a vehicle-side coil is mounted to the vehicle and connected to the electrical energy storage device, the charging installation comprising:
a ground-side coil and a plurality of strip-shaped temperature sensors arranged in first and second layers one above the other, and wherein main directions of extension of the temperature sensors of said first and second layers enclose an angle of approximately 90° therebetween and are disposed in a fixed positional relationship to said ground-side coil; at least one heat emitting device mounted to the vehicle in a fixed positional relationship to the vehicle-side coil; said at least one heat emitting device being configured to be activated at a start of a charging process and said at least one temperature sensor being configured to detect said at least one heat emitting device.
