    Abstract: A power supplier in one aspect of the present disclosure includes an outputter, a first pack parallel coupler, a second pack parallel coupler, an output voltage switch, and a controller. Each of the first pack parallel coupler and the second pack parallel coupler includes pack couplers. The pack couplers are configured to be coupled by battery packs. The output voltage switch is configured to switch an electrical coupling state between the second pack parallel coupler and the outputter. The controller is configured to determine an output mode of the outputter. The output mode corresponds to a magnitude of voltage to be outputted from outputter. The controller is configured to control the output voltage switch based on a result of determination.

    Abstract: A battery pack of one aspect of an embodiment of the present disclosure comprises a battery, a control unit, a pair of external terminals, a first current cut-off unit, and a second current cut-off unit. The control unit determines whether the first current cut-off unit and the second current cut-off unit are normal or abnormal when neither charge nor discharge of the battery is performed. When the first current cut-off unit and the second current cut-off unit are both normal, the control unit turns the first current cut-off unit and the second current cut-off unit to an energized state. When at least one of the first current cut-off unit and the second current cut-off unit is abnormal, the control unit turns the first current cut-off unit or the second current cut-off unit to a cut-off state.

    Abstract: A battery pack in the present disclosure comprises: a battery; a switching element that is provided in a discharge path from the battery to an external load and that is configured to complete or interrupt the discharge path; a control circuit that operates by receiving a supply of an electric power from the battery, that conducts an electric current through the switching element so as to allow discharge from the battery to the external load, and upon occurrence of an abnormality in the battery or the external load during the discharge, that interrupts the switching element so as to inhibit the discharge from the battery to the external load; and a protection circuit that monitors an operating condition of the control circuit and that interrupts the switching element when the control circuit is inoperative.
