DETAILED DESCRIPTION

(11) Embodiments of the present disclosure are described herein. It is to be understood, however, that the disclosed embodiments are merely examples and other embodiments can take various and alternative forms. The figures are not necessarily to scale; some features could be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

(12) As those of ordinary skill in the art will understand, various features illustrated and described with reference to any one of the figures can be combined with features illustrated in one or more other figures to produce embodiments that are not explicitly illustrated or described. The combinations of features illustrated provide representative embodiments for typical applications. Various combinations and modifications of the features consistent with the teachings of this disclosure, however, could be desired for particular applications or implementations.

(13) FIG. 1 discloses an example prior art electrical power supply system 100. The prior art power system 100 comprises a main power supply 110, a subpanel 104, two transformers 106, two outlets 108 and an EV plug-in charger 102. Power supply systems of the prior art typically have components (e.g., high voltage outlets) that are exposed. Additionally, the exposed components may not be esthetically pleasing, which may be undesirable for certain finished garages, for example. Moreover, power supply systems of the prior art tend to be static and, therefore, may be difficult to modify and/or upgrade. The various components (e.g., sub panel 104, transformer(s) 106, and outlet(s)) 108 typically are securely fastened (e.g., using screws or bolts) to an underlying mounting structure and the electrical connections between the components are made with securely fastened conduit, making it difficult to replace or upgrade components.

(14) FIG. 2 discloses an example embodiment of a power supply system 200 in accordance with the present disclosure. The power supply system 200 includes a sub panel 204, a first pair of a swappable transformer module 206a and a swappable outlet module 208a, and a second pair of a swappable transformer module 206b and a swappable outlet module 208b. The sub panel 204 may be placed onto a mounting base plate 202 and electrically connected to a main input line 210. During operation of the power supply system 200, the main input line 210 may provide an alternating current (AC) power supply at a particular voltage. In some embodiments, the main input line 210 will provide a voltage of at least 220 volts (220V). The sub panel 204 includes three breaker switches 212. The sub panel 204 also includes a plurality of outlets. Each breaker switch 212 may shut off power to one or more outlets, thereby shutting off power to swappable transformers that are electrically connected to those outlets.

(15) In some embodiments, a swappable transformer module may be securely or permanently fixed to the swappable outlet module to which the transformer is paired. In these embodiments, the pair of a swappable transformer module and the swappable outlet module can be placed on the mounting base plate 202 together at the same time as a single unit. Similarly, the paired swappable transformer module and swappable outlet module may be swapped out or removed from the mounting base plate 202 together. In some embodiments, a swappable transformer module may be separable from the swappable outlet module to which the swappable transformer module is paired. In these embodiments, either swappable module may be placed on the mounting base plate 202 separately from the swappable module to which it is paired. Similarly, either swappable module may be removed from the mounting base plate 202 without removing the swappable module to which it is paired. For example, if a paired swappable transformer module and swappable outlet module are placed on the mounting base plate 202, the swappable transformer module may be removed from the mounting base plate 202 without removing the paired swappable outlet module from the mounting base plate 202. A new paired swappable outlet module may then be placed on the mounting base plate 202 to replace the swappable outlet module that was removed.

(16) FIG. 3 discloses an example embodiment of a power supply system 300 in accordance with the present disclosure. The power supply system 300 includes a sub panel 304 electrically connected to a main input line 310 that can provide an alternating current (AC) power supply. During operation of the power supply system 300, the main input line 310 will have a particular voltage associated with it and the sub panel 304 will be electrically connected to the main input line 310. The sub panel 304 is connected to four swappable transformer modules 306a, 306b, 306c, and 306d. In other embodiments, a sub panel may be connected to more or fewer than four swappable transformer modules.

(17) The sub panel 304 includes three breaker switches 312. Each breaker switch 312 may be electrically connected to one or more of the swappable transformer modules 306a, 306b, 306c, and 306d. Each breaker switch 312 is electrically connectable to the main input line 310 such that during operation of the power supply system 300, the breaker switches 312 will be electrically connected to the main input line 310. In this manner, when the sub panel 304 is electrically connected to the main input line 310, the breaker switches can control whether or not particular swappable transformers are electrically connected to the main input line 310. In other embodiments, a sub panel may have more or fewer than three breaker switches.

(18) The power supply system 300 includes four pairs of swappable transformer modules 306a, 306b, 306c, and 306d and swappable outlet modules 308a, 308b, 308c, and 308d. For example, the swappable transformer module 306a is paired with the swappable outlet module 308a. During operation of the power supply system 300, a transformer module will provide a predetermined voltage to the outlet module to which it is paired. In some embodiments, a swappable transformer module may step down the voltage from the main input line 310. For example, if the main input line 310 is supplying 220V power, the swappable transformer 306a may provide 110V to the paired outlet module 308a. The swappable transformer module 306b may provide 220V to the paired outlet module 308b.

(19) The swappable outlet modules may comprise different outlet configurations. A swappable outlet module may have the same or a different outlet configuration as other outlet modules in the same power supply system. For example, swappable outlet module 308a has the same outlet configuration as module 308d and a different outlet configuration than module 308b and module 308c. FIG. 3A depicts example outlet configurations that can be used in outlet modules in accordance with the present disclosure.

(20) The swappable outlet modules can be used to plug accessories into power supply systems disclosed herein.

(21) The swappable outlet modules can be used to plug accessories into power supply systems disclosed herein.

(22) The power supply system 300 may be enclosed in a structure such as the structure 320. The structure 320 includes one or more openings 330 having a size and shape sufficient to allow an electrical cord plugged into one of the swappable outlet modules to pass through the opening 330. The structure 320 may include a cover or lid, such as the cover 322, which can be open or closed. When the cover 322 is open, the components of the supply system 300 may be visible and swappable components may be removed and replaced. When the cover 322 is closed, the components of the supply system 300 may not be visible. The cover 322 may include a security mechanism (not shown), such as a lock, to lock the cover 322 in a closed position. The cover 322, when locked in a closed position, may prevent or hinder non-authorized persons from gaining access to the power supply system 300.

(23) FIG. 4 discloses an example embodiment of a power supply system 400 in accordance with the present disclosure. The power supply system 400 includes a sub panel 404, a first paired swappable transformer module 406a and swappable outlet module 408a, and a second paired swappable transformer module 406b and swappable outlet module 408b. A separately swappable component of the power supply system 400 can be removed from the power supply system 400 without removing other components from the power supply system 400 and a new swappable component can be added to the power supply system 400 to replace the removed swappable component. For example, a separately swappable transformer module 406a may be removed from the power supply system 400 without removing the swappable outlet module 408b. The swappable components of the power supply system 400 may be inserted into and/or removed from the power supply system in a plug-and-play fashion.

(24) FIG. 4 discloses how accessories can be plugged into the power supply system 400. For example, an electrical cord 414 may be an electrical cord for a plug-in charger module (not shown) and electrical cord 416 may be an electrical cord for a hands-free wireless charger module (not shown). Additionally, an electrical cord or cable of an accessory, such as cord 430, may be directly connected to sub panel 404. Other accessories that may be plugged into the supply may include an invertor device, a power storage device, and a digital display device. If needed in the future, the power supply device 400 may be expanded by adding either a third paired swappable transform module and swappable outlet module or by adding a second cord or cable directly connected to the sub panel 404.
