| Claim | A battery pack, comprising: a housing including a set of walls having an interior side which defines an interior space and an exterior side which defines an exterior space, the exterior side including an interface configured to electromechanically couple the housing to an electrical device; a set of battery terminals, the set of battery terminals including a first subset of battery terminals and a second subset of battery terminals for providing a rated output voltage to the electrical device; a converter element residing in the interior space of the housing, the converter element having a first position and a second position; at least one switch, the at least one switch being configurable between a first state and a second state, wherein the at least one switch is in the first state when the converter element is in the first position and is in the second state when the converter element is in the second position; and a set of battery cells residing in the interior space of the housing, the set of battery cells electrically coupled to the set of battery terminals, wherein when the at least one switch is in the first state the battery cells provide the rated output voltage to the electrical device through the first subset of battery terminals only and when the at least one switch is in the second state the battery cells provide the rated output voltage to the electrical device through the first subset of battery terminals and the second subset of battery terminals. The battery pack, as recited in claim 1 , wherein the set of battery cells including a first subset of battery cells and a second subset of battery cells. The battery pack, as recited in claim 2 , wherein the at least one switch is configured to couple the first subset of battery cells and the second subset of battery cells in a parallel configuration as a default configuration. The battery pack, as recited in claim 2 , wherein the switching network is configured to couple the first subset of battery cells and the second subset of battery cells to provide a low rated output voltage as a default. The battery pack, as recited in claim 2 , wherein the switching network is configured to couple the first subset of battery cells and the second subset of battery cells to provide a medium rated output voltage. The battery pack, as recited in claim 1 , wherein when the switching network is in the first state the battery pack provides a low rated output voltage and when the switching network is in the second state the battery pack provides a medium rated output voltage. A battery pack for providing power to a first electrical device having a low rated operating voltage and a second electrical device having a medium rated operating voltage, the battery pack comprising: a set of battery terminals, the set of battery terminals including a first subset of battery terminals and a second subset of battery terminals for providing a rated output voltage to the electrical device; a set of battery cells including a first subset of battery cells and a second subset of battery cells; a single electromechanical interface configured to couple the battery pack to the first electrical device and to the second electrical device and provide an output voltage to the coupled electrical device; a switching network that (1) electrically couples the first subset of battery cells and the second subset of battery cells in parallel when the electromechanical interface is coupled to the first electrical device to provide a low rated output voltage from the battery pack to the first electrical device through the first subset of battery terminals only, wherein the low rated output voltage corresponds to the low rated operating voltage and (2) electrically couples the first subset of battery cells and the second subset of battery cells in series when the electromechanical interface is coupled to the second electrical device to provide a medium rated output voltage from the battery pack to the second electrical device through the first subset of battery cells and the second subset of battery cells, wherein the medium rated output voltage corresponds to the medium rated operating voltage. A battery pack, as recited in claim 7 , wherein the single electromechanical interface comprises a pair of power terminals configured to mate with a pair of power terminals of the first electrical device and a pair of power terminals of the second electrical device. A battery pack, as recited in claim 7 , wherein the switching network is configured to couple the first subset of battery cells and the second subset of battery cells to provide the low rated output voltage as a default. A battery pack, as recited in claim 7 , wherein the electromechanical interface receives a mechanical input from the second electrical device to convert the switching network from electrically coupling the first subset of battery cells and the second subset of battery cells in the low rated output voltage to the medium rated output voltage. A battery pack, as recited in claim 7 , wherein the switching network couples the first subset of battery cells and the second subset of battery cells in the medium rated output voltage upon the electromechanical interface coupling to the second electrical device. A battery pack, as recited in claim 11 , wherein the switching network couples the first subset of battery cells and the second subset of battery cells in the low rated output voltage upon the electromechanical interface decoupling from the second electrical device. A battery pack, as recited in claim 7 , wherein upon the battery pack coupling with the first electrical device the first subset of battery terminals mate with a pair of electrical device power terminals and the second subset of battery terminals mate with a pair of electrical device signal terminals and upon the battery pack coupling with the second electrical device the first subset of battery terminals mate with a first pair of electrical device power terminals and the second subset of battery pack terminals mate with a second pair of electrical device power terminals. |
