    Abstract: In one embodiment, a device obtains sensor data indicative of three dimensional (3-D) orientations of primary and secondary wireless power transfer (WPT) charging coils. The secondary coil is mounted to a vehicle and the primary coil provides charge to the secondary coil during charging. The device detects misalignment between the primary and secondary WPT coils based on the sensor data. The device determines a coil alignment correction to offset the detected misalignment. The device sends control commands to one or more actuators to implement the coil alignment correction by moving one or more of the coils, either directly (e.g., via directly-coupled actuators) or indirectly (e.g., via the suspension of a vehicle).

  • Patent number: 11018532
    Abstract: A wireless power charger (WPC) integrated into a charging pad (CP) includes a wireless power transmitter (WPT), a location sense mechanism (LSM), a transport mechanism (TM) and a Central Control Unit (CCU). The LSM discovers and conveys the position of a portable device to the CCU when the device is placed on the CP to have its battery wirelessly charged. The LSM uses RF signaling and other capabilities in wireless connectivity standards to detect location of device. With information from the LSM, the CCU, via the TM, moves the WPTM in close proximity to the device. Once at the device position, the WPTM senses the location of the receiver coil in the device, adjusts its position via the TM to gain strong alignment and provides power wirelessly. When charging is complete or if the device is removed from the charging pad, the WPTM returns to its home-base location.

  • Patent number: 11005298
    Abstract: In a wireless power transfer operation, the operating parameters are adjusted to improve efficiency by reducing the transmit and receive coil currents as follows. First, the transmitter causes the receiver to reduce the receive coil current to the lowest value based on the transmitter/receiver communication while still delivering the same amount of power to the load as before the AC current was adjusted to the minimum value. Then the transmitter may change the operating parameters to increase or preserve the power provided to the receiver without decreasing efficiency or with only small decrease in efficiency, or with increasing the efficiency. For example, the transmitter may increase the VBRG voltage (the DC voltage powering the transmit coil) or the operating frequency to maintain or increase output power levels at lower or the same AC and DC current levels. Other features are also provided.

  • Patent number: 10978902
    Abstract: A wireless charging device includes a wireless charging transmitter transmitting a charging signal to a signal gain module to generate at least one gain signal. The signal gain module includes an insulation substrate with an upper surface thereof provided with a first conductive wire. The first conductive wire makes at least one turns arranged along the inner edge of the insulation substrate. The lower surface of the insulation substrate is provided with a second conductive wire whose position corresponds to the position of the first conductive wire. A connecting element is arranged between the first conductive wire and the second conductive wire, such that the first conductive wire is electrically connected to the second conductive wire through the connecting element. The present invention provides a charging signal with high intensity to avoid the low charging efficiency caused by deflection and too long a distance.
