The invention is related generally to power supplies and other power sources and chargers and particularly to inductive charging, and to improvements, systems and methods for use thereof, such as improved transfer of wireless power to mobile devices and batteries.
With the increased use of mobile devices, many methods and protocols for wireless and wired connectivity and communication between nearby devices (several centimeters to meters) and also between devices and the wider network of farther devices (tens of meters to thousands of kilometers) are proliferating. For near devices, Bluetooth, WiFi, Wireless USB, Zigbee, Near Field Communication (NFC), HDMI, USB, Firewire, RS232, GPIB, etc., and other specialized device or application specific protocols are common, while for larger distances devices may include wireless technologies such as 2G, 3G, 4G, GSM, Edge, WiMAX, EVDO, Satellite, Optical, or GPS etc. or wired technologies such as Ethernet, Dial up modem, DSL, Fiber, Power Line, etc. may coexist in a single device.
Described herein are various systems and methods for use with power supplies and other power sources and chargers and particularly those that use inductive charging, including systems and methods for use thereof, such as improved transfer of wireless power to mobile devices and batteries.
FIG. 1 shows an illustration of a circuit in accordance with an embodiment.
With the proliferation of mobile devices in recent years, the area of powering and charging these devices has attracted more attention. The vast majority of the electronic devices in use today are powered and/or charged through conduction of electricity through wires from a power supply or charger to the device. While this method has proven to be efficient for most stationary devices, recently, there has been an interest in providing wireless methods for powering or charging one or several mobile devices, batteries, or electronics devices. The advantages include the ability to eliminate a charger and/or power supply cord and the possibility of implementing a universal charger/power supply that can be able to charge/power multiple devices one at a time or simultaneously. The so called �wireless power� methods can also be generally divided into conductive and inductive methods. While the conductive methods use flow of current from a charger into the mobile devices and/or battery to provide power and therefore are not strictly speaking wireless, they offer geometries where a user can place a device on a pad or similar object and receive power through matching contacts on the back of a device or an after market cover or �skin� and the pad without �plugging in� the device. Methods based on an array of connectors or strips of metal in a pad that can power mobile devices conductively have been proposed.
Contextually Aware Inductive Charger/Receiver
In accordance with some embodiments described herein, various methods are described by which the wired and/or wireless power devices and chargers or power supplies can provide additional connectivity and communications capabilities. In this way, in addition to charging, during the charging or docking process, other activities that are useful to the user can be implemented. While most of the description below is based on wired and/or the inductive method, the embodiments described here can be implemented with traditional wired charging and/or power and wireless charging and/or power through the inductive method or the conductive method or the magnetic resonance method, optical, or other methods for power transfer some of which have been described above. Inductive methods of power transfer are described below as an example of the more general wireless power transfer.
Improvements in Thermal Performance and Efficiency
Additional Uses and Implementations of Inductive Charging
In accordance with some embodiments described herein, a device is described by which the wireless charger and/or power supply is a device that is powered by a power source from another device such as the power available from the USB or PCMCIA port or similar from a laptop computer or a peripheral hub or consumer electronic or communication device such as a music player, TV, video player, stereo, or car stereo USB or other outlets which include power. The charger can also be incorporated directly into a battery so that a battery can charge another battery wirelessly. While most of the description below is based on the inductive method, the embodiments described here can be implemented with either the inductive method or the conductive method or the magnetic resonance method, optical, or other methods for power transfer some of which have been described above. Inductive methods of power transfer are described below as an example of the more general wireless power transfer.
Improvements in Charging Efficiency and Other Features
In accordance with some embodiments described herein, features can be provided to improve charging efficiency, usage, and other features.
