Convertible battery pack

摘要

A power tool system includes a first power tool having a first power tool rated voltage, a second power tool having a second power tool rated voltage that is different from the first power tool rated voltage, and a first battery pack coupleable to the first power tool and to the second power tool. The first battery pack is switchable between a first configuration having a first battery pack rated voltage that corresponds to the first power tool rated voltage such that the first battery pack enables operation of the first power tool, and a second configuration having a convertible battery pack rated voltage that corresponds to the second power tool rated voltage such that the battery pack enables operation of the second power tool.

1. 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 couple the housing to an electrical device; a converter element residing in the interior space of the housing, the converter element being configurable between a first position and a second position and including a projection extending from the interior space; 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; a set of battery cells residing in the interior space of the housing, the set of battery cells including a first subset of battery cells and a second subset of battery cells, wherein when the at least one switch is in the first state the first subset of battery cells is connected to the second subset of battery cells in series and when the at least one switch is in the second state the first subset of battery cells is connected to the second subset of battery cells in parallel; wherein the converter element projection is positioned to receive a mechanical input from the electrical device to reconfigure the converter element from the first position to the second position.
