20080197804 | Power transmission control device, power reception control device, non-contact power transmission system, power transmission device, power reception device, and electronic instrument - 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. | 08-21-2008 |
