Abstract: A power supply control apparatus includes: a current supply switching section that switches between a current restricting state, in which a current to be supplied from a storage battery to electrical equipment is restricted to a predetermined upper limit current or less, and a current non-restricting state, in which a current exceeding the upper limit current is allowed to be supplied from the storage battery to the electrical equipment; and a current supply control section that executes current restriction processing to cause the current supply switching section to set up the current restricting state before an engine is started, the engine having been stopped by an idling stop function.

Abstract: Systems and methods for supplying power to an electronic device are provided. A first power limit is received from the electronic device at a transmitter. The transmitter input power is set to correspond to the first power limit. The transmitter supplies power corresponding to the transmitter input power to the electronic device to initiate charging, and an electrical value associated with the transmitter input power is monitored. During monitoring, the first electrical value is compared to a predefined second electrical value, the power supply to the receiver is discontinued based on the monitoring, and the transmitter input power is adjusted to correspond to a second power limit based on the comparison.

Abstract: A non-contact charging system includes a power receiving device including a secondary coil, and a non-contact charger including a primary coil and a controller. The primary coil performs charging of the power receiving device through the secondary coil in a non-contact manner. Upon receiving a signal representing an abnormality of the power receiving device or detecting an abnormality of the charging in the non-contact charger, the controller stops the charging temporarily and executes procedures for restarting the charging when a first predetermined time has lapsed from the reception of the signal representing the abnormality or the detection of the abnormality of the charging.

Abstract: A non-contact charger includes a position detector, a determination unit, a primary coil, a coil moving unit, and a controller. The position detector detects placement of an electronic device, which incorporates a secondary coil, onto a top plate of the non-contact charger. The determination unit determines whether the electronic device is placed onto the top plate of the non-contact charger from a lateral direction. When the determination unit determines that the electronic device is placed onto the top plate from the lateral direction, the controller instructs the coil moving unit to wait for a predetermined period of time in moving the primary coil. After the waiting for the predetermined period of time to delay the movement of the primary coil, the controller moves the primary coil toward a position of the secondary coil of the electronic device.
