Abstract

An apparatus for a power system. The apparatus includes multiple electrical power sources and an enclosure operatively connected to the power sources at multiple input terminals. Multiple loads operatively connect to the enclosure at multiple output terminals by multiple cables. The enclosure includes the input terminals and the output terminals and a controller unit. Multiple selection units operatively connect to the controller unit, multiple power converters are connected to multiple connection paths. The selection units connect to at least one of multiple switches connected in the connection paths. Multiple sensor units are operatively attached to the controller unit which is configured to sense multiple parameters in the connection paths. Responsive to the parameters sensed by the sensor units, the selection units select the connection paths between the electrical power sources and the loads.

First claim

What is claimed is:

1 . An apparatus comprising:
a controller; a sensor unit coupled to the controller and configured to sense one or more parameters in in a plurality of connection paths, wherein plurality of connection paths comprise paths between a plurality of electrical power sources and a plurality of electrical loads; and a selection unit, controlled by the controller, configured to select one of the plurality of connection paths to provide power from one of the plurality of electrical power sources to one of the plurality of electrical loads, wherein the selection is based on the one or more parameters sensed by the sensing unit.

2 . The apparatus of claim 1 , wherein the selection unit is configured to provide power from the one of the plurality of electrical power sources to the one of the plurality of electrical loads using a power converter associated with the selected one of the plurality of connection paths.

3 . The apparatus of claim 1 , wherein the plurality of electrical power sources comprises an AC power source and a DC power source.

4 . The apparatus of claim 1 wherein the one or more parameters comprise coloumbic charge, voltage, current, temperature, energy, power, or impedance.

5 . The apparatus of claim 1 , wherein the selection unit is further configured to select the one of the plurality of connection paths based on a grid tariff of at least one utility grid connected to the apparatus.

6 . The apparatus of claim 1 , wherein one or more of the plurality of connection paths comprises a cable having a connector plug corresponding to a connector receptacle of one of the plurality of electrical loads.

7 . The apparatus of claim 6 , wherein the connector plug comprises at least one of a DC-to-AC converter or an AC-to-DC converter.

8 . The apparatus of claim 6 , wherein the connector plug houses one or more of the sensor unit or the selection unit.

9 . The apparatus of claim 6 , wherein the cable houses one or more of the sensor unit or the selection unit.

10 . The apparatus of claim 1 , wherein the selection unit is further configured to select a power converter for the selected one of the plurality of connection paths, the selected power converter comprising a DC-to-DC converter, a DC-to-AC converter, a AC-to-DC converter, or an AC-to-AC converter.

11 . The apparatus of claim 1 , wherein the plurality of electrical power sources comprises one or more of DC power sources, AC power sources, batteries, storage devices, DC generators, photovoltaic modules, wind turbines, AC generators, AC utility grid, or DC utility grid.

12 . The apparatus of claim 1 , wherein the plurality of electrical loads comprise one or more of batteries, storage devices of electrical vehicles (EV), storage devices of the power system or a utility grid.

13 . The apparatus of claim 1 , further comprising an enclosure operatively connected to the plurality of electrical power sources at input terminals and connected to the plurality of electrical loads at output terminals, wherein the enclosure houses the controller, the sensor unit, and the selection unit.

14 . A method comprising:
sensing one or more parameters in a plurality of connection paths between a plurality of electrical power sources and a plurality of electrical loads; selecting one of the plurality of selection paths based on the one or more parameters sensed by the sensing unit; and providing power from one of the plurality of electrical power sources to one of the plurality of electrical loads using the selected one of the plurality of selection paths.

15 . The method of claim 14 , wherein providing power comprises providing power by operating a power converter through the selected path based on a power demand of the one of the plurality of electrical loads.

16 . The method of claim 14 , wherein providing power comprises converting the provided power from AC to DC or from DC to AC.

17 . The method of claim 14 , wherein the one or more parameters comprise coloumbic charge, voltage, current, temperature, energy, power, or impedance.

18 . The method of claim 14 , wherein selecting the one of the plurality of selection paths further comprises selecting based on a grid tariff of at least one utility grid connected to the apparatus.

19 . The method of claim 14 , wherein providing power comprises connecting the one of the plurality of electrical power sources to the one of the plurality of electrical loads using a cable having a connector plug corresponding to a connector receptacle of one of the plurality of electrical loads.

20 . The method of claim 19 , further comprising converting power via a converter located in the connector plug, wherein the converter comprises at least one of a DC-to-AC converter or an AC-to-DC converter.

21 . The method of claim 14 , wherein selecting the one of the plurality of paths comprises selecting a power converter for the selected one of the plurality of connection paths, the selected power converter comprising a DC-to-DC converter, a DC-to-AC converter, a AC-to-DC converter, or an AC-to-AC converter.
