Publication number: 20130252051Abstract: A battery system including: a secondary battery (7A) including a stacked electrode body housed in a battery can (11A), a positive electrode terminal and the battery can (11A) being electrically connected; a secondary battery (7B) including a stacked electrode body housed in a battery can (11B), a positive electrode terminal and the battery can (11B) being electrically connected; a cell can voltage sensor (9A) that measures a first voltage of the battery can (11A); a cell can voltage sensor (9B) that measures a second voltage of the battery can (11B); and a BMU (15) that receives information corresponding to the measured first and second voltages of the cell can voltage sensors (9A, 9B). The BMU (15) activates expansion detection information based on the information when the first voltage increases and the second voltage decreases substantially simultaneously with the increase, thereby enabling detection of presence or absence of expansion.Type: ApplicationFiled: August 1, 2011Publication date: September 26, 2013Applicant: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Yasuaki Hiramura, Akira Takeyama

Publication number: 20120131869Abstract: The building of the present invention includes a wall making a boundary of a room, an inner wall formed by a group including first and second tubular structures and arranged on the wall as one body, and an air conditioner arranged in the room. The first tubular structure has a first ventilation hole, where gas blown into the first tubular structure from the air conditioner and passed through the first tubular structure with substantially no leakage is blown out, at a to-be-arranged position of a first storage equipment which is to be arranged in the room. The second tubular structure has a second ventilation hole, where the gas blown into the second tubular structure from the air conditioner and passed through the second tubular structure with substantially no leakage is blown out, at a to-be-arranged position of a second storage equipment which is to be arranged in the room.Type: ApplicationFiled: November 22, 2011Publication date: May 31, 2012Applicant: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Yasuaki Hiramura, Keiichiro Tanaka

Patent number: 7638978Abstract: A battery protection device may include a thermally responsive operating plate having two plates secured together, the two plates having different coefficients of thermally expansion, an electrically conductive member, and a stopper with which the thermally responsive operating plate can be interlocked. The battery protection device may have a recoverable region current cutoff state, where the thermally responsive operating plate is not interlocked with the stopper, and a contact and dissociation of the thermally responsive operation plate with and from the electrically conductive member can be repeatedly realized. The battery protection device may have an unrecoverable region current cutoff state, where the thermally responsive operating plate is interlocked with the stopper and the thermally responsive operation plate is unrecoverably dissociated from the electrically conductive member.Type: GrantFiled: December 21, 2006Date of Patent: December 29, 2009Assignee: Samsung SDI Co., Ltd.Inventors: Masaki Koike, Yasuaki Hiramura

Publication number: 20080182171Abstract: The present invention relates to a negative material for a non-aqueous rechargeable battery and a non-aqueous rechargeable battery including the same. The negative material for a non-aqueous rechargeable battery includes lithium vanadium oxide that is obtained by mixing a lithium compound such as lithium carbonate (Li2CO3) and a vanadium compound such as vanadium pentaoxide (V2O5) with an organic acid such as oxalic acid ((COOH2) to obtain an organic acid salt precursor and firing the organic acid salt precursor. The negative material for a non-aqueous rechargeable battery can improve charge and discharge characteristics of a non-aqueous rechargeable battery due to uniform composition.Type: ApplicationFiled: December 18, 2007Publication date: July 31, 2008Inventors: Hideaki Maeda, Masaki Koike, Yasuaki Hiramura, Susumu Hiyama, Sabro Shinkai, Manabu Katsumi, Sung-Soo Kim
