Title:
An accumulating electricity device provided with the current interrupting device
Document Type and Number:
Japanese Patent JP6142886
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power storage device capable of suppressing malfunctions of a current breaking device by suppressing generation of flexure moment to the current breaking device via a conductive member when an electrode assembly is inserted into a case.SOLUTION: A power storage device comprises: a case; first and second electrode terminals provided on a terminal attachment wall of the case; and an electrode assembly, a first conductive member, a second conductive member, and a current breaking device that are housed in the case. The first conductive member and the second conductive member are connected with a positive electrode or a negative electrode of the electrode assembly respectively . The current breaking device is arranged between the terminal attachment wall and the electrode assembly, and connected in series between the first electrode terminal and the first conductive member to connect or disconnect an energization path from the electrode assembly to the first electrode terminal. A first spacer in contact with the electrode assembly is further provided between the current breaking device and the electrode assembly.
