Claim:
1. A battery powered surgical handpiece system comprising: a surgical instrument including a housing containing a motor and a motor controller portion, and a battery pack configured for detachably coupling to the surgical instrument, the battery pack including a thermoelectric cooler, wherein, when the battery pack is operatively coupled to the surgical instrument, the thermoelectric cooler is thermally coupled between the motor controller portion and a thermally conductive element supported by the battery pack, the thermally conductive element being movable between a first position where the thermally conductive element is spaced apart from an internal housing of the battery pack and a second position where the thermally conductive element is thermally coupled to and between an external housing of the battery pack and the internal housing of the battery pack, and wherein the battery pack further includes a microcontroller-controlled actuator configured for selectively actuating the thermally conductive element between the first position and the second position.
