    Abstract: 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.

    Abstract: 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. The layout and design of the charging base pads, the current flow through the charging base pads, and the sequencing of charging base pad activation and current flow implemented may dramatically affect the power transfers and practicality of such dynamic systems. The sequencing and control of these coils may need to be capable of managing the individual coils with minimal infrastructure as well as be capable of distributing the required power from the power grid to these pads efficiently and safely, and may comprise charging base pads, controllers to control the power flow to, activation of, and current flow direction within the base pads.
