A battery pack having a power-supply terminal, a ground terminal, and a communication terminal includes: a secondary battery that is connected to the power-supply terminal and the ground terminal; a resistive element that is connected to the communication terminal and the ground terminal; a switch unit that is connected in parallel to the resistive element and that is connected to the communication terminal and the ground terminal; and a controller that performs control of switching an ON state and an OFF state of a switch of the switch unit. The battery pack may further include a non-contact charging unit that performs non-contact charging, the resistive element may be a temperature sensor, and the controller may switch the switch of the switch unit to the ON state when the non-contact charging is started by the non-contact charging unit.
