Claim 19:
20. A standardized provisioning for an electrical vehicle charging station, comprising:
a precast concrete center pad configured to be moved and placed at a desired location in a vehicle parking lot for electric vehicles, wherein the center pad is a rectangular pad and includes a top surface, a bottom surface, first and second side surfaces and first and second end surfaces;
a power conduit stub-up and a communications conduit stub-up that extend vertically through an opening in the vehicle parking lot, wherein the power and communications conduit stub-ups are located at the desired location and are connected to lines placed underneath the vehicle parking lot;
a central junction box formed as a rectangular aperture in the center pad extending between the top surface and the bottom surface, for receiving the power and communications conduit stub-ups through the opening in the vehicle parking lot, wherein the central junction box includes a divider plate for dividing the power conduit stub-up and associated power connections from the communications conduit stub-up and associated communications connections, wherein a cover plate is received atop the central junction box for sealing the central junction box from the elements;
a plurality of outer junction boxes including a first set of rectangular apertures formed in the center pad and located substantially proximate to the first end surface and also including a second set of rectangular apertures formed in the center pad and located substantially proximate to the second end surface, wherein each of the outer junction boxes is configured to provide a power connection and a communication connection to a respective electrical charging dispenser;
a plurality of raceways extending through the center pad from the central junction box to each of the respective outer junction boxes to provide passageways for the power and communications connections between the stub-ups and the plurality of electrical charging dispensers; and
a plurality of isolating plates each respectively set atop one of the outer junction boxes to provide electrical and corrosion isolation between the center pad and the respective electrical charging dispensers.
