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.
