  • Patent number: 10707698
    Abstract: A power transmitter (101) for inductively transferring power to a power receiver (105) comprises a resonance circuit (201) comprising a transmitter coil (103) for generating a power transfer signal. A sampler (511) samples a current through, or voltage over, the transmitter coil (103). A message receiver (509) receives messages load modulated onto the power transfer signal based on the samples. A driver (203) generates a drive signal for the resonance circuit (201) and a resonance modification circuit (505) reduces the resonance frequency of the resonance circuit (201) by slowing a state change for a resonating component of the resonance circuit (201) for a fractional time interval of the cycles of the drive signal. A sample time controller (513) controls the sample times in response to at least one of start-times and end-times of the fractional time intervals, and specifically may set the sample times to be within the fractional time intervals.

  • Patent number: 10647203
    Abstract: A system includes a conversion circuit of a vehicle system that conductively couples a conversion device with first motors of the vehicle system. The electrical conversion device converts non-electrical energy into conversion-based electric current that is conducted to the first motors. The system also includes a storage circuit of the vehicle system that conductively couples a storage device with second motors of the vehicle system. The storage device supplies stored electric current to the second motors of the vehicle system. The system also includes a controller configured to control the second motors to brake and generate charging electric current that is conducted through the storage circuit to charge the storage device. The conversion circuit and the storage circuit are separate circuits such that the storage device is not charged with the conversion-based electric current conducted in the conversion circuit.

  • Patent number: 10644528
    Abstract: A system includes a charging station and one or more receiving devices receiving wireless power from the charging station. The charging station includes an orientation adaptable antenna (OAA). The OAA may generate a magnetic field component parallel to the plane of the OAA to charge devices oriented at 90 degrees with respect to the OAA. The OAA may generate a magnetic field along different directions within the plane parallel to the OAA. The OAA may be able to adjust the direction of the field to couple to devices with antennas in different orientations. The OAA may further produce a magnetic field normal to the plane of the OAA. The OAA may adjust the relative strengths the various directional components of the magnetic field to align the field normal to the antennas of the receiving devices in up to three dimensions, simultaneously charge receiving devices in different orientations, or both.

  • Patent number: 10637257
    Abstract: A dual battery mobile terminal and a wireless charging system are provided. The wireless charging system includes a main battery, a secondary battery, a wireless receive module and a charging control module. The wireless receive module senses a wireless charging signal, and converts the sensed wireless charging signal into a voltage and current signal. The charging control module in turn outputs the voltage and current signal outputted from the wireless receive module to charge the main battery or the secondary battery individually, or output the voltage and current signal to charge the main battery and the secondary battery simultaneously. Thereby, the control of the dual battery charging may be achieved.

  • Patent number: 10637301
    Abstract: Multiple wireless power receiving devices operating in accordance with potentially different wireless charging protocols may be placed on a wireless power transmitting device. The wireless power transmitting device sends a frequency-shift-keying packet. If a wireless power receiving device is compliant with a first wireless charging protocol, the device responds to the frequency-shift-keying packet with an amplitude-shift-keying response packet. If the wireless power receiving device is compliant with a second wireless charging protocol, the wireless power receiving device will fail to respond to the frequency-shift-keying packet and the wireless power transmitting device responds by stopping and starting wireless power transmission and awaiting an amplitude-shift-keying packet from the wireless power receiving device in accordance with the second wireless charging protocol.
