The production cost of a power source device is reduced by providing a first current control switch, of which the operation is controlled by a first control means and which limits a current flowing in a direction toward each of a plurality of first power storage device groups, for each of the plurality of first power storage device groups in which a plurality of power storage devices are electrically connected to each other in series or in parallel, or in series and parallel, and which are electrically connected to each other in parallel; and by providing a second current control switch, of which the operation is controlled by a second control means and which limits a current flowing in a direction opposite to the direction toward the plurality of first power storage device groups, for a power storage device group which includes the second power storage device group, in which the plurality of first power storage device groups are electrically connected to each other in parallel, and has a greater number of the power storage devices than the first power storage device group. |
