a transmission-side communication unit capable of communication; and a transmission-side control unit configured to control power transmission of the power transmission unit based on information communicated by the transmission-side communication unit, and a slidable object includes: a power receiving unit configured to contactlessly receive power from the power transmission coil; a determination unit configured to determine whether or not to transmit power from the power transmission coil to the power receiving unit; a receiving-side communication unit configured to transmit, to the transmission-side communication unit, information indicating a determination made by the determination unit as to whether or not to transmit power; and a power storage unit configured to supply power to the determination unit and does not supply power to the load L. ## Claims ### Claim 1 A power supply system for contactlessly supplying power supplied from a power supply, to a load in a slidable object capable of sliding with respect to a body of a vehicle, the body of the vehicle comprising: a power transmission unit capable of transmitting power supplied from the power supply; a transmission-side communication unit capable of communication; and a transmission-side control unit configured to control power transmission of the power transmission unit based on information communicated by the transmission-side communication unit, the slidable object comprising: a power receiving unit configured to contactlessly receive power from the power transmission unit; a determination unit configured to determine whether or not to transmit power from the power transmission unit to the power receiving unit; a receiving-side communication unit configured to transmit, to the transmission-side communication unit, information indicating a determination made by the determination unit as to whether or not to transmit power; and a power storage unit configured to supply power to the determination unit and does not supply power to the load. ### Claim 2 (depends on 1) The power supply system according to claim 1, wherein the power storage unit supplies power to the determination unit and the receiving-side communication unit. ### Claim 3 (depends on 1) The power supply system according to claim 1, wherein the slidable object further comprises an operation unit capable of being operated by a user, and the determination unit determines whether or not to transmit power from the power transmission unit to the power receiving unit in accordance with an operation of the operation unit. ### Claim 4 (depends on 1) The power supply system according to claim 1, further comprising: a voltage detection unit capable of detecting a voltage of the power storage unit, wherein the determination unit determines that power is to be transmitted from the power transmission unit to the power receiving unit when the voltage detection unit detects that the voltage of the power storage unit has dropped below a predetermined voltage. ### Claim 5 (depends on 1) The power supply system according to claim 1, wherein the power storage unit stores power received by the power receiving unit. ### Claim 6 (depends on 1) The power supply system according to claim 1, wherein the slidable object is a slide seat that is slidably fixed to the body of the vehicle. ### Claim 7 (depends on 2) The power supply system according to claim 2, wherein the slidable object further comprises an operation unit capable of being operated by a user, and the determination unit determines whether or not to transmit power from the power transmission unit to the power receiving unit in accordance with an operation of the operation unit. ### Claim 8 (depends on 2) The power supply system according to claim 2, further comprising: a voltage detection unit capable of detecting a voltage of the power storage unit, wherein the determination unit determines that power is to be transmitted from the power transmission unit to the power receiving unit when the voltage detection unit detects that the voltage of the power storage unit has dropped below a predetermined voltage. ### Claim 9 (depends on 3) The power supply system according to claim 3, further comprising: a voltage detection unit capable of detecting a voltage of the power storage unit, wherein the determination unit determines that power is to be transmitted from the power transmission unit to the power receiving unit when the voltage detection unit detects that the voltage of the power storage unit has dropped below a predetermined voltage. ### Claim 10 (depends on 2) The power supply system according to claim 2, wherein the power storage unit stores power received by the power receiving unit. ### Claim 11 (depends on 3) The power supply system according to claim 3, wherein the power storage unit stores power received by the power receiving unit. ### Claim 12 (depends on 4) The power supply system according to claim 4, wherein the power storage unit stores power received by the power receiving unit. ### Claim 13 (depends on 2) The power supply system according to claim 2, wherein the slidable object is a slide seat that is slidably fixed to the body of the vehicle. ### Claim 14 (depends on 3) The power supply system according to claim 3, wherein the slidable object is a slide seat that is slidably fixed to the body of the vehicle. ### Claim 15 (depends on 4) The power supply system according to claim 4, wherein the slidable object is a slide seat that is slidably fixed to the body of the vehicle. ### Claim 16 (depends on 5) The power supply system according to claim 5, wherein the slidable object is a slide seat that is slidably fixed to the body of the vehicle.
