摘要： When connecting a plurality of cells in parallel, an operation to calculate an inrush current flowing when a pair of cells are selected from the cells for the parallel-connection and parallel-connected for all cell combinations. A cell combination, whose inrush current is the largest in the cell combinations which are judged that the calculated inrush current is less than or equal to a predetermined upper limit current value, is set as a cell combination to parallel-connect the cells.

摘要： The power storage device includes a battery group in which n series circuits C1 (wherein n represents an integer of 2 or greater) are connected in parallel and a battery controller controlling a switching device based on allowable charge/discharge power of the capacitor. The series circuit C1 includes a capacitor and the switching device which are connected in parallel. The battery controller controls the switching device to maximize the allowable charge/discharge power of the battery group.
