Abstract: A communication device in one aspect of the present disclosure includes a storage, a first wireless communication circuit, an information obtaining circuit, and a storing processing circuit. The first wireless communication circuit receives first information through an antenna. The first information is wirelessly transmitted from a first transmission device. The first information corresponds to the first transmission device. The first transmission device is configured to be connected to an electric work machine or is connected to the electric work machine. The information obtaining circuit obtains the first information through the first wireless communication circuit in response to a first event being occurred or having occurred. The storing processing circuit stores the first information from the information obtaining circuit into a storage.

Abstract: In one aspect, the present disclosure discloses a charging system including a battery pack and a charger. The battery pack includes a first battery pack terminal, a second battery pack terminal, and a third battery pack terminal. The second battery pack terminal is spaced apart from the first battery pack terminal in an intersecting direction. The intersecting direction intersects a removal direction of the battery pack from the charger. The charger includes a first charger terminal, a second charger terminal, and a third charger terminal. The second battery pack terminal is arranged so as to pass through an area spaced apart from the third charger terminal in a process of removing the battery pack from the charger.

Abstract: A battery pack in one aspect of the present disclosure includes a communication terminal and a detector, and supplies electric power to an external device. The communication terminal receives a first signal, a second signal, and a third signal. The first signal has a first potential, the second signal has a second potential, and the third signal has a third potential. The first potential, the second potential, and the third potential are different from one another. The detector determines a potential at the communication terminal, to thereby detect the first signal, the second signal, or the third signal in accordance with the determined potential.
