  • Patent number: 12057719
    Abstract: A battery pack is configured to supply electric power to an electric work machine, such as a power tool or outdoor power equipment. The battery pack includes a first battery-signal terminal and a second battery-signal terminal. The first battery-signal terminal outputs, to the electric work machine, a first signal indicating that discharging is to be prohibited or permitted. The second battery-signal terminal outputs, to the electric work machine, a second signal indicating that discharging is to be prohibited or permitted. Thus, two communication paths are provided for transmitting signals to permit or prohibit discharging of the battery pack.

  • Patent number: 11979049
    Abstract: An electric work machine (1), such as a power tool, comprises a motor (50), a manipulatable part (12) such as a trigger switch, and a control part (36). The motor is energized with electric current supplied by a battery pack (22). By manipulating the manipulatable part, the control part energizes the motor. The control part also acquires information concerning the state of the battery from the battery pack, and, if appropriate based on the information obtained from the battery pack, takes measures (such as limiting a discharge current) to restrain, delay and possibly avert the performance of a protection (discharge-prohibited) operation by the battery pack.
