摘要： Dynamic wireless charging systems may involve coordinating multiple charging base pads to provide coordinated, continuous power transfers to a moving receiver along the distance in which the dynamic wireless charging system is installed. These dynamic systems may require a large number of coils (base pads) which may be components in base array networks (BAN modules). The BAN modules may provide for simplified installation and system design wherein the BAN modules may be preassembled and self-contained, drop-in-place units. The layout and design of the BAN modules may be such that they may contain charging base pads, local controllers, distribution circuitry, and switching controls. The sizing of the BAN modules may dramatically affect the usability and practicality of such dynamic systems. The sizing of the BAN modules may be dependent upon the pitch between vehicle pads on electric vehicles and base pad pitch within the BAN modules.

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.
