Patent number: 8629656Abstract: A battery pack includes one or more cell blocks in which one or more secondary battery cells are connected in series and/or in parallel, and a control section for measuring a voltage of the one or more cell blocks to detect an abnormality of a cell block on the basis of a measurement result. The control section calculates a time differential of the voltage for the one or more cell blocks on the basis of the measured voltage, extracts a first time differential which is maximum and a second time differential which is minimum from the time differentials of the voltage for the one or more cell blocks, and determines that a cell block corresponding to the second time differential is abnormal in a case where a difference between the first time differential and the second time differential is less than a prescribed value.Type: GrantFiled: February 16, 2012Date of Patent: January 14, 2014Assignee: Sony CorporationInventors: Shoichi Nishiyama, Masaru Hiratsuka, Hiroyuki Suzuki, Takehiko Tanaka

Patent number: 7976973Abstract: A battery includes a spirally wound electrode body in which a cathode and an anode are layered with a separator in between and spirally wound. The spirally wound electrode body is attached with at least one lead on the spirally-winding center side. The cathode has a cathode current collector having a pair of opposed faces, an outer-face cathode active material layer provided on the spirally-winding outer face side of the cathode current collector, and an inner-face cathode active material layer provided on the spirally-winding inner face side thereof. A thickness of the inner-face cathode active material layer is smaller than a thickness of the outer-face cathode active material layer. An outer face active material region provided with only the outer-face cathode active material layer is formed to be overlapped with the lead on the spirally-winding center side of the cathode.Type: GrantFiled: May 17, 2007Date of Patent: July 12, 2011Assignee: Sony CorporationInventors: Shoichi Nishiyama, Hiroshi Inoue
