CONTACTLESS POWER RECEIVING DEVICE, AND CONTACTLESS CHARGING SYSTEM
First Claim
1. A contactless power receiving device connected by a connection terminal to an equipment, wherein the contactless power receiving device supplies power to a load of the equipment, the contactless power receiving device comprising:
- a secondary coil that intersects with an alternating magnetic flux generated from a primary coil, which is supplied with AC power; and
a control unit that supplies induced electromotive force of the secondary coil to the load,wherein the control unit determines a charging amount of the load and determines whether or not to supply power to the load based on the determined charging amount.

Abstract
A contactless power-receiving device, which is connected to equipment via a connection terminal and which supplies power to the load for the equipment, provided with: a secondary coil which intersects the alternating magnetic flux generated from a primary coil to which an alternating power is supplied; and a control unit which supplies induced electromotive force of the secondary coil to the load. The control unit determines the amount of charge in the load and determines whether or not to supply power to the load on the basis of the determined amount of charge.

8. A contactless charging system comprising:
-
a contactless power transmitting device including a primary coil that generates an alternating magnetic flux when supplied with AC power; and a contactless power receiving device including a secondary coil that intersects with the alternating magnetic flux generated from the primary coil, wherein the contactless power receiving device supplies the AC power, which is supplied from the primary coil through the secondary coil, to a load of an equipment connected by a connection terminal, wherein the contactless power receiving device includes a control unit that supplies the load with an induced electromotive force of the secondary coil generated by intersecting the alternating magnetic flux generated from the primary coil; and the control unit determines a charging amount of the load and determines whether or not to supply power to the load based on the determined charging amount.
