BASE DISTRIBUTION NETWORK FOR DYNAMIC WIRELESS CHARGING

摘要

Dynamic systems may require a large number of coils (charging pads) which may be installed into the roadway to wirelessly provide power to electric vehicles as they are traveling along the roadway. The current in each of these coils may need to be turned on and off as a vehicle drives over the coils in order to efficiently utilize power and properly convey power to the passing vehicles. The supply network behind these coils may need to be capable of managing the individual coils with minimal infrastructure and cost as well as be capable of distributing the required power from the power grid to these pads efficiently and safely. The supply network may include charging coils, switches, local controllers, and distribution circuitry within a modular element, which may receive power from external sources and may be controlled by a central controller.

主权项

1. A device for distributing power, the device comprising:
a first set of charging coils configured to provide wireless power; a first set of switches configured to selectively control power to the first set of charging coils; a second set of charging coils configured to provide wireless power; a second set of switches configured to selectively control power to the second set of charging coils; and a control unit configured to control the first and second sets of switches, the first and second sets of charging coils being interleaved, and the first set of switches being configured to respectively couple one charging coil of the first set of charging coils to the control unit and the second set of switches being configured to respectively couple one charging coil of the second set of charging coils to the control unit.
