摘要： A battery pack includes a plurality of lithium battery cells, an analog thermo sensing member, and an analog switch. The analog thermo sensing member detects, in an analog form, a battery temperature of at least one of the plurality of lithium battery cells, and outputs an output preventing signal if the battery temperature is over a first predetermined temperature. The analog switch element is the plurality of lithium battery cells in series, and is switched, based on the output preventing signal, to a state in which a current is prevented from flowing in the plurality of lithium battery cells.

摘要： A cordless power tool uses a lithium battery as a power source of a motor and is provided with an overcurrent protection circuit. The circuit allows an overcurrent to instantaneously flow at the start-up time of the motor and shuts off an overcurrent which may flow when the motor is brought into a locked state during the use of the power tool.
