ABSTRACT:
An electric power storage apparatus is formed of a plurality of series-connected cells to obtain a desired working voltage, each of the cells being constituted by one electric double-layer capacitor or a plurality of electric double-layer capacitors connected. The plurality of cells are series-connected so that the combined withstanding voltage is not lower than Vr+Vs where Vr represents the working voltage of the cells and Vs represents the withstanding voltage of one of the cells. The apparatus further includes connectors for detachably holding each of the cells respectively, and a circuit in which a diode is connected in parallel to each of the cells, so that a failed one of the cells can be detached and replaced by a new one while the working voltage of the cells is kept within a tolerance limit.
