A battery pack including at least one secondary battery and supplying power to predetermined equipment is disclosed. In the battery pack, charging current to the secondary battery supplied from an external charging device is cut off to suspend charging the secondary battery until receiving a predetermined instruction from the external charging device. The battery pack may comprise a first communication circuit unit for communicating with the external charging device; a first switching circuit unit for cutting off the charging current from the external charging device to the secondary battery; and a control circuit unit for controlling the first switching circuit unit based on information received by the first communication circuit unit. The control circuit unit instructs the first switching circuit unit to cut off the charging current from the external charging device to the secondary battery and suspend charging the secondary battery until receiving the predetermined instruction from the external charging device via the first communication circuit unit.
