Patent number: 8404375Abstract: An electrical battery includes a plurality of electrical energy generating elements formed by at least one electrochemical cell that is packaged in a flexible sealed envelope, and a system for the mechanical and thermal conditioning of the elements. The conditioning system forms a structural body made from thermally conductive material. The body has two longitudinal members and a plurality of cross-members connecting the longitudinal members so as to form between the cross-members housings in which respectively a generating element is disposed. The body includes a circulation path for a thermal conditioning fluid. The path has two channels, respectively upstream and downstream, that are formed respectively in a longitudinal member and passages formed in each of the cross-members. The passages are in fluid communication on each side with respectively the upstream channel and the downstream channel.Type: GrantFiled: April 8, 2009Date of Patent: March 26, 2013Assignee: Dow Kokam France SASInventor: Fabien Gaben

Patent number: 8399114Abstract: A battery module includes a first unit cell, a second unit cell, a first exhaust chamber, and a second exhaust chamber. The first unit cell is disposed so that a positive electrode terminal faces the first direction. The second unit cell is connected in series to the first unit cell, the negative electrode terminal is disposed so as to face the first direction, and the second unit is disposed so as to be adjacent to the first unit cell. The first exhaust chamber is disposed so as to face the positive electrode terminal of the first unit cell, and discharges a gas which is emitted from the positive electrode terminal of the first unit cell. The second exhaust chamber is disposed so as to face the positive electrode terminal of the second unit cell, and discharges a gas generated from the positive electrode terminal of the second unit cell. The end surface of the second unit cell in the first direction and the outer surface of the first exhaust chamber in the first direction are flush with each other.Type: GrantFiled: July 22, 2011Date of Patent: March 19, 2013Assignee: Panasonic CorporationInventors: Daisuke Kishii, Takuya Nakashima
