LARGE CAPACITY ENERGY STORAGE APPARATUS OF CELL CARTRIDGE

摘要

PURPOSE: A cell cartridge in a high capacity energy storage device can change current and voltage capacity by controlling and changing units of a battery unit according to the storage capacity of a cell cartridge, thereby having various capacities. CONSTITUTION: A cell cartridge in a high capacity energy storage device a unit battery (11) charging electricity; a tray (12) fixing a plurality of unit cells; units coupling a plurality of trays to form one unit; a cartridge (14) coupling the units and fixing the units to the upper part and the lower part of the cartridge; connectors (15) electrically connecting the units fixed to the cartridge.
