Embodiment Construction

[0036] figure 1 An exemplary embodiment of a device 10 for charging a mobile terminal with magnetic coupling is schematically shown.

[0037] The charging device 10 is, for example, vehicularly mounted on an automobile vehicle (not shown). A mobile terminal (not shown) is, for example, a mobile phone, a laptop computer, a touch screen tablet computer, a digital camera, or the like.

[0038] The charging device 10 comprises a first charging module 11 designed to form a charging signal at a first charging frequency F1. In the following part of the description, the non-limitative case is considered, where the first charging module 11 is a WPC charging module 11 and the first charging frequency F1 is in the range of 100 and 200 kHz.

[0039] The charging device 10 also includes at least one primary coil 13, associated with the WPC charging module 11, composed of a set of N T turn composition. In order to optimize charging at the first charging frequency F1, the charging device...

Abstract

A device (10) for charging a mobile terminal by magnetic coupling, includes a first charging module (11) designed to form a charging signal at a first charging frequency, a primary coil (13) composed of a set of turns, a ferromagnetic body (14), a second charging module (12) designed to form a charging signal at a second charging frequency, higher than the first charging frequency. Furthermore, the charging device includes first routing elements (150) designed to connect / disconnect the primary coil (13) to / from the first charging module (11) and to / from the second charging module (12), elements (16) for adjusting the number of turns on the primary coil (13) and elements (19) for saturating the ferromagnetic body (14) at the second charging frequency. A charging method is also described.

Description

technical field [0001] The present invention relates to a device and a method for charging a mobile terminal with magnetic coupling. The invention has a particularly advantageous application, although this is by no means restrictive, in a charging device installed on board a motor vehicle. Background technique [0002] Charging devices using magnetic coupling that enable wireless charging of mobile terminals (mobile phones, laptops, touch screen tablets, digital cameras, etc.) are becoming more and more common. [0003] Conventionally, charging devices using magnetic coupling include a conductive coil, called a "primary coil", which is connected to a charging module. When charging the mobile terminal, the charging module forms a charging signal, which enables a current to flow in the primary coil, the strength of which varies with time. The primary coil thus powered generates a variable magnetic field. [0004] The mobile terminal includes a receiver module that includes ...
