Description:TECHNICAL FIELD
[001] The present invention relates generally to a system for enhancing controlled charging of a battery of a user device and method thereof.
BACKGROUND
[002] Portable electronic devices such as smart phones, tablets, notebooks and other electronic devices have become an everyday need in the way we communicate and interact with others. The frequent use of these devices may require a significant amount of power, which may easily deplete the batteries attached to these devices. Therefore, a user frequently needed to plug in the device to a power source, and recharge such device. This may require having to charge electronic equipment at least once a day, or in high-demand electronic devices more than once a day.
[003] When the power level of the battery is depleted, the device is generally inoperable, and the battery may require recharging before the device becomes operable. In order to avoid this situation, some current devices provide an indicator indicating power remaining in the battery, however, these indicators only provide approximate information relating to the remaining life of the battery. A wireless power transmission or a wireless energy transfer refers to a technology of wirelessly transferring electric energy to desired devices. However, according to the wireless power transmission technology of the related art, power must be constantly transmitted regardless of the existence of the wireless power receiver that receives the power, causing the waste of the power and battery damage.
[004] Therefore, there is a need for a system which overcomes the aforementioned problems.

[0030] Figure 1 illustrates a view showing a wireless power transmission system according to one embodiment of the disclosure.
[0031] In an embodiment, the wireless power transmission system includes a power source 10, a power transmission unit 20, a power reception unit 30, a rectifying circuit 40 and a load 50. The power generated from the power source 10 is provided to the power transmission unit 20, such that the power transmission unit 20 transmits the power using resonance to the power reception unit 30, which is resonant with the power transmission unit 20 and has the same resonant frequency value as that of the power transmission unit 20. The power transferred to the power reception unit 30 is transferred via the rectifying circuit 40 to the load 50. The load 50 may be a battery or a predetermined apparatus which needs power.
[0032] The power transmission unit 20 includes a transmission coil unit 21 and a transmission resonant coil unit 22. The transmission coil unit 21 is connected to the power source 10, such that an AC current flows through the transmission coil unit 21. When AC current flows through the transmission coil unit 21, the AC current is induced to the transmission resonant coil unit 22 physically spaced apart from the transmission coil unit 21 due to electromagnetic induction. The power transferred to the transmission resonant coil unit 22 is transmitted using resonance to the power reception unit 30 which forms a resonance circuit with the power transmission unit 20. The power transmission using resonance, the power can be transmitted between two LC circuits which are impedance-matched with each other. The power transmission scheme using the resonance can transmit the power farther than the power transmission scheme using the electromagnetic induction with the higher power transmission efficiency.
[0033] The power reception unit 30 includes a reception resonant coil unit 31 and a reception coil unit 32. The power transmitted from the transmission resonant coil unit 22 is received in the reception resonant coil unit 31, so that the AC current flows through the reception resonant coil unit 31. The power transmitted to the reception resonant coil unit 31 is transferred by electromagnetic induction to the reception coil unit 32. The power transferred to the reception coil 32 is transferred through the rectifier circuit 40 to the load 50.
[0034] The detection power applying unit 12 may generate detection power used to detect the location of the wireless power receiver 60 and provide the detection power to the switch unit 14. If the detection power having the resonant frequency f1 is applied to each transmission resonance unit 20, the current measured in the wireless power transmitter 100 is minimized because the inductor and the capacitor of each transmission resonance unit 20 appear in an open state at the self-resonant frequency f1, so that impedance is maximized. The current measuring unit 13 measures the internal current generated from the wireless power transmitter 100 by the applied detection power, and the measured current may be supplied to the controller 15. In this case, the controller 15 may detect the location of the wireless power receiver 60 based on the measured current.
[0035] The switch unit 14 performs a switching operation in order to sequentially supply the detection power, which is received from the detection power applying unit 12, to the transmission resonance units 20. In other words, the switch unit 14 sequentially supplies the detection power to the transmission resonance units 20 according to the control of the controller 15, so that the location of the wireless power receiver 60 can be detected.
[0036] The transmission coil unit 21 is connected to the switch unit 14, and has AC current flowing therein to generate a magnetic field. In addition, the transmission coil unit 21 transmits the magnetic field to the transmission resonance coil unit 22, which is physically spaced apart from the transmission coil unit 21, through the electromagnetic induction phenomenon. The controller 15 may control the overall operation of the wireless power transmitter 100.
[0037] The wireless power transmitter 100 generates AC power having the mutual-change resonant frequency f2 through the power supply unit 11 to transmit energy through the transmission resonance unit 20 corresponding to the location of the wireless power receiver 60. In other words, the actual energy transmission is achieved with the mutual-change resonant frequency f2 instead of the self resonant frequency f1. In this case, the controller 15 may control the power supply unit 11 such that the AC power having the mutual-change resonant frequency f2 is generated.
[0038] Figure 2 illustrates a schematic diagram of apparatus for battery life estimation.
[0039] In an embodiment, the battery 222 is a rechargeable battery such as, but not limited to, a nickel cadmium, nickel metal hydride or lithium ion type battery. The system 224 for monitoring or estimating the remaining life of the battery 222 includes a processor 226 which is configured to monitor the amount of power, or energy, that is being delivered by or supplied to the battery via a set of sensors 227, which may be located at various locations within the device 210. The processor 226 can also be used for other device functionality (the processor 226 may be, but need not be, a processor that controls the various functions of the device 210, for example) and does not have to be solely for use in the system 224. The processor 226 is further electrically connected to the display screen 214 for transmitting information relating to the power level of the battery 222 to the user such as in the form of a battery life indicator. In general, and as indicated by context, components are electrically connected when an electrical signal in one affects the other.
[0040] Figure 3 illustrates waveforms for wireless power transmission with selective range, which may get unified in single waveform.
[0041] In an embodiment, a transmitter 301 comprising a plurality of antennas in an antenna array, may adjust the phase and amplitude of a power transmission waves 307, among other attributes, being transmitted from each antenna of the transmitter 301. A receiver may receive multiple signals 307 a from multiple antenna elements and the composite of those signal may be essentially zero, if the signals add destructively. Antenna elements of the transmitter may transmit the exact same power transmission signal (i.e., comprising power transmission waves having the same features), but however each of the power transmission signals 307 a may arrive at the receiver, offset from each other by 180 degrees, and therefore these power transmission signals may “cancel” one another. Signals offsetting one another in this way may be referred to as “destructive interference.”
[0042] Figure 4 illustrates wireless power transmission with selective range, where a plurality of pockets of energy may be generated along various radii from transmitter.
[0043] In an embodiment, the transmitter 702 may generate pocket-forming through wireless power transmission with selective range 700, which may include one or more wireless charging radii 704 and one or more radii of null in a particular physical location 706. A plurality of electronic devices 701 may be charged or powered in wireless charging radii 704. Thus, several spots of energy may be created, such spots may be employed for enabling restrictions for powering and charging electronic devices 701. As an example, the restrictions may include operating specific electronics in a specific or limited spot, contained within wireless charging radii 704. For example the receivers of electrical devices 701 may be in a room where a transmitter 702 may be mounted on the ceiling. Selective ranges for establishing pockets of energy using power transmission waves, which may be represented as concentric circles by placing an antenna array of the transmitter 702 on the ceiling or other elevated location, and the transmitter 702 may emit power transmission waves that will generate ‘cones’ of energy pockets. In some embodiments, the transmitter 701 may control the radius of each charging radii 704, thereby establishing intervals for service area to create pockets of energy that are pointed down to an area at a lower plane, which may adjust the width of the cone through appropriate selection of antenna phase and amplitudes.
