Abstract: An electric working machine in one aspect of the present disclosure includes a motor, a controller, and a setter. The controller is configured to change a rotational state of the motor, in response to an establishment of a condition for change after the motor is initiated, from a low speed rotation to a high speed rotation. The setter is configured to set, based on a situation in the motor in the low speed rotation, a control variable of the motor in the high speed rotation and/or the condition for change.

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.
