Abstract: A power tool includes a motor and a controller in a power tool housing. A battery pack interface is defined on and/or in the power tool housing. A receptacle is defined on and/or in the power tool housing to removably accommodate a wireless communication adapter such that the wireless communication adapter is disposed entirely within a shell of the power tool and no portion of the wireless communication adapter extends beyond an outer contour of the power tool housing. At least one communication terminal is disposed within the receptacle and is electrically connectable to the wireless communication adapter. The controller outputs to the at least one communication terminal a signal indicating a charge level of a battery pack attached to the battery pack interface, a number of hours of operation of the power tool, a power tool overheated alert, and/or a battery pack overloaded alert.

Abstract: A communicator in one aspect of the present disclosure includes a connector, a communication circuit, and a communication controller. The connector is electrically coupled to an electric working machine. The communication circuit performs wireless communication. The communication controller cyclically transmits operational information without specifying a recipient via the communication circuit in response to an operating mode of the communication controller being set to an operation-transmission mode. The operational information indicates an operating state of the electric working machine.

Abstract: A battery-powered portable tool includes: a battery pack containing at least one all-solid-state battery cell; a tool main body, on which and/or inside which the battery pack is mountable and from which the battery pack is demountable; and a plurality of components contained in the battery pack and/or in the tool main body. The plurality of components is disposed in a first layout or physical configuration when the temperature is low and is disposed in a second layout or physical configuration when the temperature is high. The first layout or physical configuration differs from the second layout or physical configuration.

Abstract: A power tool system includes a hand-held power tool having a power tool housing accommodating a motor, and a battery pack interface electrically connected to the motor within the power tool housing. A battery pack includes a battery pack housing accommodating at least one battery cell and a power tool interface electrically connected to the at least one battery cell within the battery pack housing. The power tool interface is configured to be physically and electrically connected to and disconnected from the battery pack interface of the power tool. A wireless communicator is attached to or accommodated within the battery pack housing. The wireless communicator is configured to wirelessly communicate with an external device using radio waves while the power tool interface of the battery pack is physically and electrically connected to the battery pack interface of the hand-held power tool.

Abstract: An information setting apparatus in one aspect of the present disclosure comprises a clock information device, an information receiving device, a permission time calculating device, and an information setting device. The permission time calculating device calculates an operation permission time based on current time information stored in the clock information device and on start time information received by the information receiving device. The information setting device sets operation limitation information, including the operation permission time to at least one of a battery pack or an electrically-driven working machine.

Abstract: A battery pack includes: a battery; a notification unit configured to notify that a fully charged state is reached; a determination unit configured to determine whether the fully charged state is reached; a processing unit configured to execute a full charge process if the fully charged state is determined, the full charge process being one of causing the notification unit to make a notification and maintaining a possible state, in which making a notification is possible; and a factor detection unit configured to detect occurrence of a predetermined increase factor during execution of the full charge process, the increase factor leading to increase in a chargeable capacity of the battery as compared with the time when the fully charged state is determined. The processing unit stops the full charge process if occurrence of the increase factor is detected during execution of the full charge process.
