Abstract
A power tool comprising a housing, an interface configured to receive a battery pack, a trigger for user control of power tool operation, at least one sensor configured to measure an operational characteristic of the power tool, and a controller. The controller is configured to receive a control signal from the trigger, control the power tool in response to the control signal, receive power tool operational data from the at least one sensor indicative of the operational characteristic of the power tool, and provide additional energy to the power tool via an auxiliary energy supply within the power tool housing based on the operational characteristic of the power tool.
