Abstract
Official abstract text for this publication.
A charger includes a power receiving unit, a power storage unit, and a power transmission unit. The power receiving unit is configured to receive, through wireless power supply via radio waves, power transmitted from a power transmitting device disposed in a vehicle. The power storage unit is configured to be supplied and charged with the power received by the power receiving unit. The power transmission unit is configured to transmit, through wireless power supply via electromagnetic induction, the power stored in the power storage unit to an electrical device that is to be charged.
First claim
Opening claim text (preview).
1 . A charger comprising: a power receiving unit configured to receive, through wireless power supply via radio waves, power transmitted from a power transmitting device disposed in a vehicle; a power storage unit configured to be supplied and charged with the power received by the power receiving unit; and a power transmission unit configured to transmit, through wireless power supply via electromagnetic induction, the power stored in the power storage unit to an electrical device that is to be charged. 2 . The charger according to claim 1 , wherein the power transmission unit is attached to a vehicle on-board component disposed in a passenger compartment. 3 . The charger according to claim 1 , wherein the power transmission unit is prohibited from transmitting the power stored in the power transmission unit to the electrical device when a remaining amount of the power is less than or equal to a predetermined low-amount determination value. 4 . The charger according to claim 3 , wherein the power transmission unit is configured to transmit, through wireless power supply via electromagnetic induction, the power received by the power receiving unit to the electrical device when the remaining amount is less than or equal to the low-amount determination value and the power receiving unit is receiving the power transmitted from the power transmitting device. 5 . The charger according to claim 1 , wherein the power receiving unit is prohibited from receiving the power transmitted from the power transmitting device when a remaining amount of the power stored in the power receiving unit is greater than or equal to a predetermined full-amount determination value. 6 . The charger according to claim 1 , further comprising a physical switch configured to switch between a state in which power transmission from the power transmission unit to the electrical device is permitted and a state in which the power transmission is prohibited.
