A power tool may include a power tool controller located within the power tool housing, the power tool controller configured to: receive a signal from battery pack, the signal indicative of a temperature of the battery pack, and do not limit a drive unit power if the temperature is less than a temperature threshold.

Abstract: A motor driven apparatus including a motor, a first switching module and a second switching module on a current path from one terminal of a battery to another terminal of the battery, and a MCU connected to the first and second switching module. The first and second switching module are connected in series to each other, while the first switching module is connected to the motor and adapted to drive the motor. The MCU is adapted to control the first second switching module separately. The MCU is further adapted to, upon its energization, attempt to control the second switching module to be in a cut-off state until the MCU determines that the first switching module is normal. The MCU attempts to detect failures of the switching elements in the first switching module before it enables operation of the motor.
