Abstract: The present invention proposes a sealed battery including a safety valve made of a metal plate which can be deformed by the increase of the inner pressure of the battery, and current cutting-off means which is actuated by the deformation of the safety valve, wherein the safety valve has a safety valve projection provided at its center to project toward an electric power generating element of the battery, a disk having a central aperture in which the safety valve projection is inserted and gas apertures through which gas is passed is fixed between the safety valve and the electric power generating element, a thin metal plate to which one of the leads of the electric power generating element is connected is attached to the element side of the disk to close the central aperture, and the safety valve projection is welded to the thin metal plate through the central aperture. The present invention proposes another sealed battery including a safety valve made of a metal plate which can be deformed by the increase of the inner pressure of the battery, and current cutting-off means which is actuated by the deformation of the safety valve, wherein the safety valve has a safety valve projection provided at its center to project toward an electric power generating element of the battery, a disk made of metal is fixed between the safety valve and the electric power generating element, the safety valve projection is welded to the center of the disk, the disk also has gas apertures provided at other positions than the center, and one of the leads of the electric power generating element is electrically connected to the element side of the disk. According to this invention, when the inner pressure of the battery is increased, the current can be surely cut off, and the inner pressure can be surely reduced without causing a short-circuit by the lead so that the battery can be prevented from destructive explosion.

Abstract: The battery device is made up of a modular casing (13A, 13B), a large number of secondary batteries housed in the modular casing (13A, 13B), plural cell control units (14A to 14F) and an exterior casing (11) accommodating the modular casing (13A, 13B). The modular casing (13A, 13B) has an inner casing member (26) and an outer casing member (27) and has a large number of terminal openings opened in it. The secondary batteries are housed in the modular casing (13A, 13B) via the terminal openings so that positive terminal and negative terminal are alternately exposed to outside. A pre-set number of secondary batteries are grouped together as a set, with the totality of the secondary batteries being arranged in a plurality of such sets. The cell control unit (14A to 14F) has the functions of detecting and controlling the voltage of each battery module and each secondary battery and of inputting and outputting detection and control signals. The exterior casing (11) is provided with a positive electrode terminal (18), a negative electrode terminal (19) and a transmission/reception terminal (20) of the cell control unit (14A to 14F).
