摘要:
A power reception device transmits authentication information (e.g., start code, manufacturer ID, product ID, rated power information, and resonance characteristic information) to a power transmission device before starting normal power transmission by a non-contact power transmission system. The power transmission device performs instrument authentication based on the received authentication information, and regulates the maximum transmission power is regulated to conform to a power-reception-device side rated power. The power transmission device then performs normal power transmission.

A contactless power transferring coil unit is provided. The contactless power transferring coil unit includes a flat coil, a magnetic film, and a leaking flux detecting coil. The flat coil is formed by winding a conductive wire into a spiral on a substantially flat plane. The magnetic film is disposed so as to cover one entire flat surface of the flat coil. The leaking flux detecting coil is disposed in a periphery outside an outer edge of the flat coil and the magnetic film and detects leaking magnetic flux from the flat coil.
摘要:
A power transmission device performs power-saving power transmission that transmits a small amount of power as compared with normal power transmission when the power transmission device has detected that a battery of a load has been fully charged so that the operation of a charge control device (charge control IC) of the load is maintained, thereby enabling recharging due to a charge management function of the charge control device. Since the load state of a power reception device increases when recharging has started, the power transmission device detects an increase in the load state and changes power transmission from power-saving power transmission to normal power transmission. When the power reception device has been removed during power-saving power transmission, the power transmission device detects that the power reception device has been removed, and stops continuous power transmission so that unnecessary power consumption does not occur.

A noncontact charging device includes a mounting portion, a primary transmission coil, a temperature-detecting element, and a control unit. A device charged in a noncontact manner is mounted on the mounting portion. The primary transmission coil supplies power to a secondary transmission coil provided to the device by the use of electromagnetic induction. The temperature-detecting element detects a temperature of a material mounted on the mounting portion. The control unit is configured to supply power to the primary transmission coil and terminate the power supply to the primary transmission coil when a predetermined temperature is detected by the temperature-detecting element. The temperature-detecting element is located on a side of a contact surface between the mounting portion and the primary transmission coil, and the center of the temperature-detecting element is located within a range of the diameter of the primary transmission coil from the center position of the primary transmission coil.

A noncontact power-transmission coil is provided. The noncontact power-transmission coil includes a planar coil and a magnetic layer. The planar coil is formed by winding a linear conductor in a spiral shape substantially in a single plane. The magnetic layer is formed by applying a liquid-form magnetic solution in which magnetic particles are mixed with a binder solvent, so as to cover one planar portion of the planar coil and a side-face portion of the planar coil.
