Capacitor module, bank of such modules, and storehouse housing such banks

摘要

There is disclosed a capacitor module capable of having an improved packing density and, hence, an improved energy storage density. 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. Pairs of capacitor banks arranged in this way are arranged vertically and horizontally via passages and via space permitting the modules to be taken out.
