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.

A capacitor bank using such capacitor modules is also disclosed. Furthermore, an electrical energy storehouse using such capacitor banks is disclosed. Supercapacitor cells connected in series are housed in a box-like capacitor module. A heat dissipator is mounted on an end surface of the module. Parallel monitors connected in parallel with the capacitor cells, respectively, are mounted to the heat dissipator. Such capacitor modules are stacked to form a capacitor bank. The heat-dissipating surface of each module is located on the outside of the bank and exposed. The modules are held in the bank so that they can be taken out of the bank individually. Capacitor banks making a pair are located back-to-back such that their heat-dissipating surface face outward.

Abstract: A power supply using electric double layer capacitors whose output voltages undergo great variations. The power supply further includes first, second, and third switches for switching the capacitors from a parallel connection to a series connection, and a regulating circuit powered by the capacitors. As the output voltages from the capacitors drop, the regulating circuit switches the capacitors from the parallel connection to the series connection. For example, the switches are composed of semiconductor devices. The second and third switches are operated complementarily in relation to the first switch. Electric double layer capacitors producing low terminal voltages can be used. The step-up or step-down ratio can be made smaller. High voltage hazard can be avoided and the efficiency of the power supply can be improved.
