Abstract
Description
- This application is a continuation application of U.S. patent application Ser. No. 12/353,851 entitled “Wireless Powering and Charging Station” filed on Jan. 14, 2009, which claims priority under 35 U.S.C. §119(e) to U.S. Provisional Patent Application No. 61/021,001 entitled “Wireless Powering and Charging Station” filed on Jan. 14, 2008, both of which are incorporated by reference herein in their entireties.
- Previous applications by Nigel Power LLC have described a wireless powering and/or charging system using a transmitter that sends a magnetic signal with a substantially unmodulated carrier. A receiver extracts energy from the radiated field of the transmitter. The energy that is extracted can be rectified and used to power a load or charge a battery.
- It is desirable to transfer electrical energy from a source to a destination without the use of wires to guide the electromagnetic fields. Previous attempts has often received low efficiency together with an inadequate amount of delivered power.
- Our previous applications and provisional applications, including, but not limited to, U.S. patent application Ser. No. 12/018,069, filed Jan. 22, 2008, entitled “Wireless Apparatus and Methods”, the entire contents of the disclosure of which is herewith incorporated by reference, describe wireless transfer of power.
- The system can use transmit and receiving antennas that are preferably resonant antennas, which are substantially resonant, e.g., within 10% of resonance, 15% of resonance, or 20% of resonance. The antenna(s) are preferably of a small size to allow it to fit into a mobile, handheld device where the available space for the antenna may be limited. An efficient power transfer may be carried out between two antennas by storing energy in the near field of the transmitting antenna, rather than sending the energy into free space in the form of a travelling electromagnetic wave. Antennas with high quality factors can be used. Two high-Q antennas are placed such that they react similarly to a loosely coupled transformer, with one antenna inducing power into the other. The antennas preferably have Qs that are greater than 200, although the receive antenna may have a lower Q caused by integration and damping.
- The present application describes a wireless desktop for wireless power transfer.
- An embodiment discloses a base that receives wireless power, and repeats it for use with a portable electronic device.
- In the Drawings:
-
FIG. 1 shows a block diagram of a device transmitting to a remote receiver; -
FIG. 2 shows a cross section of theFIG. 1 embodiment; -
FIG. 3 shows how the base of theFIG. 1 embodiment can repeat the signal; -
FIG. 4 shows a second embodiment; and -
FIG. 5 shows a third embodiment. - Several embodiments of wireless powering and charging station for low power portable electronic devices are disclosed herein.
- A first embodiment discloses a wireless power station for a portable electronic device, e.g. a cordless phone, with reference to
FIG. 1 . According to the embodiments, the term “wireless power station” is used to refer to a device that wirelessly transmits power that can either provide power to a device, or can charge a rechargeable battery within that device. According to the embodiment, thedevice 100 can include abase 102 which has anantenna 104 incorporated therein. Theantenna 104 can receive power via magnetically coupled resonance, shown generically as 110, from a transmitter ofmagnetic power 120 that is remote from theantenna 104. - The
transmitter 120 can produce magnetic fields as disclosed in our co-pending applications, and may include loosely coupled resonant loop/coil antennas that are preferably of high-quality factor e.g. quality factor Q larger than 500. These devices may operate in either a low-frequency range or a high frequency range. -
FIG. 2 illustrates a cross-section of the embodiment shown inFIG. 1 . Thephone 99 is mounted on thebase 100. 104 shows a cross-section of the loop/coil antenna that is integrated into the wireless charging station. This antenna receives wirelessly power from theremote transmitter 120. In the embodiment ofFIG. 2 , the integrated coil in the charging base acts as a parasitic antenna that relays and in essence focuses the magnetically-generated power to acoil form antenna 220 integrated into thephone 99. One advantage of this embodiment is that thephone 99 can then operate as a wireless receiver of power with or without the charging base. The charging base becomes a system that allows operation more effectively via repeating of the magnetic energy. - The
antenna 220 may be an integrated ferrite Rod antenna formed of aspool wound coil 222 and acapacitive device 224 in series with the spool wound coil. The inductance and capacitance together form a circuit that has an LC constant which is substantially resonant with the frequency used by thetransmitter 120, and as repeated by theantenna 104. - An advantage of
FIG. 2 embodiment is that the form factor of the structures fit well within the space provided. Theloop coil antenna 104 is round in cross-section, and fits into the roundcross section base 100. Thecoil antenna 220 is straight and cylindrical, and fits well into the straight body of the phone. Other shaped devices can of course be used. -
FIG. 3 illustrates how theprimary antenna 122 of the transmitter produces magnetic power that have electrical energy therein. This is transmitted via magnetic field coupling to asecondary antenna 104 that is integrated into the base of thepower station 100. This relays the power again via magnetic field coupling to thetertiary antenna 220 which is within the portable device. This forms a locally increased field due to the mutual coupling. In addition, as described above, the portable device may also receive power directly from the base station. - However, the inventors recognized that the
antenna 220 integrated in the portable device may be constrained by the size and/or geometry of the portable device. As such, it may be less efficient than the antenna integrated in the charging station. The less efficient antenna may make it more difficult to receive sufficient power directly from the power base station at the desired distance. The effect of the secondary antenna may be considered as that of a parasitic antenna locally magnifying the magnetic field in the vicinity of the charging station, increasing the overall efficiency of the receive antenna in the portable device. Therefore the embodiment ofFIG. 2 may increase the distance and/or efficiency and/or power density of a wireless power station. - When the
portable device 99 is placed closely enough to the primary antenna, the sameportable device 99 may also receive electrical energy directly from thepower base station 120. - Thus, the repeating station of the first embodiment may be most useful when used to obtain power at longer distances or otherwise fringe areas.
- Moreover, the magnetic coupling between charging station and portable device may have certain advantages compared to the conductive coupling using electrical contacts (the classical solution). For example, contacts in electrical charging may become soiled or oxidized. Also, an electronic charging device typically is only usable with one device, into which the connector mates. A magnetic coupled charging station may be configured to charge e.g. different types of wireless power-enabled cordless phones.
- In all of the embodiments, the portable device such as 99 is formed in a case such as 101. The case has outer dimensions. The
base 100 has a holdingportion 105 for the portable device. The holdingportion 105 includes surfaces such as 106 that are sized in a way that hold the case in place. For example, this may only hold the case on the bottom as near thesurfaces 106 inFIG. 1 . There may also be a rear holding place such as 107 which holds the portable device upright, and prevents it from falling or moving. Many different portable devices can fit within theopening 105. However, by holding thedevice 99 in a specified location, the efficiency of coupling magnetically between theantenna 104 and an antenna in the portable device may be improved. - In the embodiments, the portable device is described as being portable phone such as a cellular phone. However, in other embodiments, the portable device may be a personal digital assistant such as PDA, a portable computer such as a laptop or other portable computer, a media player, such as an iPod or others, or other portable electronic device that operates from stored power.
- In an embodiment, the
antenna 104 includes aninductive loop coil 130, in series with acapacitor 132. The coil and capacitor are selected to have high Q values, for example to provide a Q greater than 500 and even more preferably greater than 1000. In addition, the LC value of the coil is tuned to be substantially resonant with the transmission value from thetransmitter 120. - One important feature is that was noted by the inventor is that the efficiency of magnetic transmission of this type may be proportional to the size of the antennas. That is, a bigger loop antenna may produce more efficient transfer of energy. Accordingly, in an embodiment, a loop antenna is used which is integrated as close to the outer perimeter of the base 100 as possible.
- In an embodiment shown in
FIG. 1 , the base has a substantially disk shaped an outer perimeter. This allows the use of a round antenna. However, the disc outer perimeter may be any shape, and in fact a rectangular outer shape base may be used with a rectangular shaped antenna. - Embodiment 2, depicted in
FIG. 4 , is similar to embodiment 1 with abase 400,antenna 402. Electrical energy received by the wireless charging station is forwarded to theportable device 99 using conductive coupling overcontacts - In embodiments where a conductive charging is used, there may be a separate
coupling antenna loop 435 which is directly connected to the magnetic contacts. While the coupling loop is connected to the electrical contacts, theMain antenna 400 is electrically unconnected. This maintains the integrity of its impedance and matching. - Embodiment 3, depicted in
FIG. 5 , a chargingstation 500 which receives power through awired connection 510, e.g. directly from the 110/220 V mains or from a wall plug power supply as in classical solutions. This may use the same kind ofportable device 99 as in the first embodiment. The power is magnetically modulated and coupled to theantenna 220 based on magnetic coupled resonance. - Although only a few embodiments have been disclosed in detail above, other embodiments are possible and the inventors intend these to be encompassed within this specification. The specification describes specific examples to accomplish˜more general goal that may be accomplished in another way. This disclosure is intended to be exemplary, and the claims are intended to cover any modification or alternative which might be predictable to a person having ordinary skill in the art. For example, other sizes, materials and connections can be used. Other structures can be used to receive the magnetic field. In general, an electric field can be used in place of the magnetic field, as the primary coupling mechanism. Other kinds of antennas can be used. The above has described how the base can be round, but the base can also be rectangular, in which case the antenna can be either round or rectangular. Other shapes of the antennas can also be used.
- Also, the inventors intend that only those claims which use the-words “means for” are intended to be interpreted under 35 USC 112, sixth paragraph. Moreover, no limitations from the specification are intended to be read into any claims, unless those limitations are expressly included in the claims.
- Where a specific numerical value is mentioned herein, it should be considered that the value may be increased or decreased by 20%, while still staying within the teachings of the present application, unless some different range is specifically mentioned. Where a specified logical sense is used, the opposite logical sense is also intended to be encompassed.
