Abstract: A motor driven appliance in one aspect of embodiments of the present disclosure comprises a light source, a lighting unit, a motor, an operation unit, an operation detector, a reference signal output unit, a determination unit, and a control unit. The operation detector detects that the operation unit is operated, and outputs an operation detection signal that indicates that the operation unit is operated. The reference signal output unit outputs at least one reference signal that can be used as a reference for determining whether the detection by the operation detector is normal. The determination unit determines whether the operation unit is actually operated based on the operation detection signal and the at least one reference signal. The control unit controls operation of the lighting unit based on the determination made by the determination unit.

Abstract: A battery pack in one aspect of the present disclosure includes a first battery block, a second battery block, and a terminal portion. The terminal portion is configured to output a parallel voltage of the battery block and the second battery block connected in parallel in response to a state where a first electric working machine is connected to the terminal portion. The terminal portion is configured to output a first voltage of the first battery block and a second voltage of the second battery block individually in response to a state where a second electric working machine is connected to the terminal portion.

Abstract: A charging control device includes a control unit and a monitoring unit. The control unit performs at least one of controlling charging to a rechargeable battery and monitoring a state of a rechargeable battery, while outputting a state signal which indicates an operation state of the control unit. The monitoring unit determines whether or not the operation state of the control unit is a predesignated specified operation state based on the state signal outputted from the control unit.
