The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
Electric vehicles are becoming increasingly popular, and the need to charge different types of vehicles at different locations continues to increase. The development of the charging stations typically involves a bespoke planning and construction processes at locations or facilities where a person may park their vehicle for an extended period of time. As the number of vehicles that will be charged increases, the charging stations need to accommodate more and more vehicles with varying charging capabilities. The charging and updating of the different vehicles and charging connectors will also need accommodate the expansion of the industry, along with updates to standalone vehicular charging system hardware. Most vehicle charging stations are manufactured and are permanently installed with a finite number of stations and any upgrades or expansion requires removal of the entire previous system. This can make the charging stations unavailable for a prolonged period while the construction is being performed. A number of patents and or publications have been made issued that address different aspects of the problems. Exemplary examples of patents and or publication that attempt to address this/these problem(s) are identified and discussed below.
U.S. Pat. No. 5,538,361 issued on Jul. 23, 1996 to John V. Beamer and is titled Apparatus for Forming a Trench. This patent discloses a system for forming a single-walled trench comprising a pair of frame members, each having a horizontal section and a section depending from the horizontal section; a collapsing pair of wall pans having sidewalls interior to the depending portion of the frame members, a bottom floor disposed between the sidewalls, a releasing mechanism to collapse inward the sidewalls. While this patent discloses a trench form it does not provide support for internal power transmission.
U.S. Pat. No. 4,145,857 issued on Mar. 27, 1979 to Benjamin L. Tilsen and is titled Base for Mounting Electrical Equipment. This patent discloses a sectionalized structure of preformed wall panels especially adapted for use as base for burial in the earth for mounting above-ground electrical equipment such as sectionalizing cabinets, transformers, electrical switch gear boxes, and similar equipment connected to underground utility cables.

Vail and is titled Subterranean System of Electrical Conductors. This patent discloses underground wires for electrical systems of communication and improved methods of laying them. This patent is not for power transmission lines and further does not contain buss wiring where connections can be made along the length of the buss wire or strip.
U.S. Pat. No. 343,458 issued on Jun. 8, 1886 to G. S. Hull and is titled Underground Conduit for Electrical Conductors. The object of this invention is to prevent the loss of conductivity which results from the breaking of electrical conductors in test boxes and provides test pins to test the condition of each conductor. This patent does not provide buss wiring or strips to connect electrical power for a charging system. U.S. Pat. No. 11,159,033 issued on Oct. 26, 2021 to A. Molle further describes a modular electric charging apparatus providing a universal base system that can be used to install an electrical power system, with electrical distribution hubs provided from different manufacturers to be connected by electrical wiring into their unique hubs. This and all other referenced extrinsic materials are incorporated herein by reference in their entirety. Where a definition or use of a term in a reference that is incorporated by reference is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein is deemed to be controlling.
Thus, there remains a need for improved an energy infrastructure system that can be easily upgraded, expanded, and can accommodate different distribution hubs and vehicles.
The inventive subject matter provides apparatus, systems, and methods in which an energy infrastructure system comprises a raceway with first and second rails, first and second cover plates positionally affixed with respect to the first and second rails, a buss extending along at least a portion of the raceway, and a first and second current carrying structure electrically coupled to the buss, where each is configured to carry electrical current through a passageway in a cover plate. A method for updating an electrical infrastructure system is also described, comprising affixing a second distribution hub to the second cover plate, coupling the second distribution hub to draw power from the buss, and replacing the first cover plate with the second cover plate, such that the second cover plate extends along the raceway for a different length than the first cover plate.
It is an object of the energy infrastructure system to provide a universal base system that can be used to install electrical power. The universal base allows for cabinets (or electrical distribution hubs) from different manufacturers to connect electrical wiring into their unique cabinet. The cabinet can then connect into a conduit system for distribution to a plurality of vehicle charging locations for distribution. The universal base can have a variety of securing mounts to accommodate different size and shape cabinets and locations for power cable routing into the cabinets as needed for the manufacturer, electrical code and building code.
It is an object of the energy infrastructure system to have an open frame structure for setting and casting concrete around the open frame. The open frame is set level with the desired finished surface with a trench canal and the concrete can be poured into both sides of the cable trench form frame. The open nature of the cable trench form frame allows the concrete to flow around the frame and also sets the frame in the concrete. There is no removal of the frame after the concrete sets and frame is a permanent part of the structure. The frame can further include mounting locations and apparatus that can extend into the poured concrete to provide structural security to above surface mounted housings.
It is another object of the energy infrastructure system to include a support frame and canal that extends from the cabinet base. The canal is easily cut to length or multiple canals can be placed in series for extending the length. This allows for future expansion and room for additional charging stations to be added at the future. The length of the canal can also be extended at a future time without effecting the operation of installed charging stations. An insulated spacer is installed into the support frame to ensure that the canal maintains its shape and provides an electrical connection support system.
It is still another object of the modular energy infrastructure system to include a plurality of buss bar contacts. The buss bars set and/or buss cables and are secured in the insulated spacer. The buss bars extend the length of the canal and provide electrical connection at any point along the length of the canal. This also allows an installer to place a second charging connection to allow vehicles on both sides of the canal. The buss bars can also be extended in the future to provide connections for additional charging stations. The cross-section of the buss bars can also be sized, increased or changed based upon the amount of power that is being used to charge vehicles.
