Abstract

A connection-switched capacitor storage system comprises plural capacitors, parallel monitors connected with the capacitors, respectively, switches for switching the connections of the capacitors from a series combination to a parallel combination or vice versa, and a control portion. The parallel monitors bypass the charging current for the capacitors when the terminal voltages of the capacitors exceed a given voltage, thus limiting increases of the terminal voltages of initializing the terminal voltages of the capacitors to their original level. The control portion controls initialization and switching of the connections of the capacitors. The control portion causes the parallel monitors to initialize the capacitors near the voltage at which the connections of the capacitors are switched by the switches.

Description

technical field [0001] The present invention relates to a kind of connection switching control type capacitor power storage device, comprising: a plurality of capacitors; Parallel monitor, connected in parallel with each of the above-mentioned plurality of capacitors, has the function of limiting each capacitor to a value by bypassing the charging current when it is above a predetermined voltage. The initialization function on the set voltage of initialization; the switching device switches the connection of the above-mentioned multiple capacitors from series to parallel or from parallel to series; the control device controls the voltage of the above-mentioned multiple capacitors according to the voltage of the above-mentioned The initialization performed, simultaneously, controls the switching of the capacitor connection performed by the aforementioned switching means. Background technique [0002] A power storage device that combines a capacitor with an electronic circuit,...
