BASE ARRAY NETWORK DESIGN FOR MULTIPLE VEHICLE PADS
First Claim
1. A device for charging an electric vehicle, the device comprising:
- a plurality of charging coils configured to charge the electric vehicle, a length between any two charging coils of the plurality of charging coils being less than a pitch between at least two vehicle pads of the electric vehicle;
a plurality of control units configured to selectively distribute power to one of the charging coils; and
a plurality of charging coil switches configured to selectively couple one of the charging coils to one of the control units.

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.
