Problems solved by technology

If a trailing cord is snagged or jerked, the cord and connector may be damaged, or the device may be dragged to the ground
Also, the trailing cord itself is inconvenient and unsightly, especially if multiple devices are charging from a common power outlet, and the trailing cords can become tangled

Embodiment Construction

[0026] now refer to figure 1 , figure 1 A schematic representation of an embodiment of an inductively enabled power pack 300 is shown. Power pack 300 includes housing 310 containing secondary inductor 320 , flux guide 330 , electrochemical cell 340 and interface module 100 . Generally, the power pack 300 is configured as a drum with multiple electrical interfaces 302a, 302b, 302c connected to the electronic device 400 ( Figure 2a ).

[0027] According to various embodiments, the dimensions of the housing 310 and the characteristics of the electrochemical cell 340 are selected to suit various electronic devices, such as telephones, media players, game consoles, personal digital assistants (PDAs), and the like. Embodiments of the power pack thus provide inductive charging functionality to existing electronic devices without modification to the electronic devices themselves.

[0028] Because the lifetime of an electrochemical cell is shorter than the lifetime of the electron...

Abstract

An inductively enabled power pack charging system and method includes an integrated circuit for controlling inductive transfer of power to the power pack and managing communication with an external power source. The system may further include an electrochemical cell for storing energy received from the external power supply and magnetic shielding material for guiding magnetic flux away from the electrochemical cell.

Description

technical field [0001] Embodiments disclosed herein relate to batteries for electronic devices. More specifically, embodiments relate to inductive charging systems for power packs of mobile devices. Background technique [0002] Power packs are commonly used to power mobile devices such as cell phones, personal digital assistants (PDAs), media players, and more. Typically, a power pack includes a rechargeable electrochemical cell that is charged using a dedicated charger unit that draws power from a power source, such as the mains or a vehicle battery, and may be located inside or outside the device. [0003] Charger units powered from the mains or power line consist of a large plug box containing a step-down transformer and rectifier, with conductive plugs for connection to the mains socket. When in use, the plug box is plugged into the mains socket and the trailing wire is connected to the device by means of a connecting plug. If a trailing cord is snagged or jerked, th...
