State of Charge Information for a Wireless Power Transmitting Device - A simplified explanation of the abstract

This abstract first appeared for US patent application 18463932 titled 'State of Charge Information for a Wireless Power Transmitting Device

Simplified Explanation

The abstract describes a wireless power system that includes transmitting and receiving devices. The transmitting device, powered by a battery, can communicate its presence and state of charge to other devices. The battery-powered transmitting device can report its state of charge to a power receiving device before or during the power transfer phase.

  • Battery-powered transmitting device can identify its presence and state of charge to other devices.
  • The device can periodically report its state of charge to a power receiving device using in-band communication.
  • State of charge can be reported before or during the power transfer phase.
  • The device can respond to a state of charge query from the power receiving device.
  • Power receiving device can display the state of charge of the battery in the transmitting device.

Potential Applications

  • Wireless charging systems for various electronic devices.
  • Smart home systems that wirelessly charge multiple devices.
  • Electric vehicle charging stations with wireless charging capabilities.

Problems Solved

  • Eliminates the need for physical connections or cables for charging devices.
  • Provides a convenient and efficient method for charging multiple devices simultaneously.
  • Allows for easy monitoring of the battery state of charge in transmitting devices.

Benefits

  • Simplifies the charging process by eliminating the need for cables or connectors.
  • Enables a clutter-free and convenient charging experience.
  • Provides real-time information about the battery state of charge for better device management.


Original Abstract Submitted

A wireless power system may include power transmitting devices, power receiving devices, and power transmitting and receiving devices. During a configuration phase (e.g., when placed adjacent to another device), a battery-powered transmitting device may transmit information to the additional device that identifies a presence of the battery in the transmitting device. The battery-powered transmitting device may periodically report its state of charge to a power receiving device using in-band communication. The battery-powered transmitting device may report its state of charge before a power transfer phase (e.g., in the configuration phase) or during the power transfer phase. The battery-powered transmitting device may report its state of charge to the power receiving device in response to a state of charge query from the power receiving device. The power receiving device may display the state of charge of the battery of the power transmitting device.
