    Abstract: A thermal management system for an electromagnetic induction-power transfer system. The system may include a charging apparatus including a housing that defines an interface surface. An accessory or induction-power consuming apparatus may be positioned proximate to the interface surface. The housing of the charging apparatus may include a power source and a power-transferring coil coupled to the power source and positioned below the interface surface. A thermal mass may be positioned within the housing and spaced apart from the interface surface. The housing may include a thermal path that is configured to conduct heat from the interface surface to the thermal mass.

    Abstract: Systems and methods for modular charging of vehicles are described. For example, a method may include connecting a vehicle to a charger using a charging plug interface that includes a first pair of conductors connected to alternating current terminals of an on-board alternating current-to-direct current converter of the vehicle and a second pair of conductors connected to terminals of a battery of the vehicle; and charging the battery of the vehicle via direct current flowing through the second pair of conductors concurrent with charging of the battery via alternating current flowing through the first pair of conductors to power the on-board alternating current to direct current converter.

    Abstract: Implementations described and claimed herein provide systems and methods for supplying voltage to a load and battery. In one implementation, an unregulated DC-to-DC converter is electrically connected to a first energy source to down convert a first voltage supplied by the first energy source. A load is electrically connected to the unregulated DC-to-DC converter to receive the down converted first voltage. A regulated DC-to-DC converter is electrically connected to the unregulated DC-to-DC converter to regulate the down converted first voltage to a second voltage. A second power source is electrically connected to the regulated DC-to-DC converter to charge the second power source using the second voltage, and the second power source is switchably connectable to the load.

    Abstract: Power transfer systems including a direct current source and a plurality of outputs operable in several modes. A ground mode may couple an output to circuit ground and a current mode may couple the output to the direct current source. The power transfer system may also include a controller configured to iteratively select a pair of outputs from the plurality of outputs. Once a pair is selected, the controller may set a first output of the pair of outputs to the current mode and the second to ground mode for a determined duration. After the duration has passed, the controller may set the first output to the ground mode and the second output to the current mode for the same duration. Thereafter the controller may select another pair of outputs.

    Abstract: A transmitter device in an inductive energy transfer system includes a first transmitter coil operatively connected to a first resonant circuitry. A receiver device includes a first receiver coil operatively connected to a first resonant circuitry. The first transmitter coil and the first receiver coil form a first transformer. The transmitter device, the receiver device, or both the transmitter and receiver devices can also include an auxiliary coil or inductor, which may form an auxiliary transformer. Energy can be transferred from the transmitter device to the receiver device using the first transformer or the auxiliary transformer. The transfer of energy may be adaptively adjusted based on the efficiency of the energy transfer. For example, the transfer of energy can be adjusted based on the operating conditions of the load.

    Abstract: A first electronic device optically communicates with a second electronic device. Each of the devices includes one or more optical transmitters, one or more optical receivers, and one or more lenses where each of the lenses includes at least a first and a second optical path that are optically isolated from each other. When the first electronic device transmits data to the second electronic device, an optical transmitter of the first electronic device transmits to an optical receiver of the second electronic device via the first optical paths of the lenses of the first and second electronic devices. Similarly, when the first electronic device receives data from the second electronic device, an optical receiver of the first electronic device receives from an optical transmitter of the second electronic device via the second optical paths of the lenses of the first and second electronic devices.
