    • A battery module 100 includes a plurality of cells 10 arranged in a grid array. The cells 10 arranged in a row direction are connected together in parallel by a first connecting member 20. The cells 10 arranged in a column direction are connected together such that the cells 10 adjacent to each other in the column direction are connected together in series by a second connecting member 30. When an internal short-circuit occurs in any one of the cells 10, the first connecting member 20 connected to the cell 10 in which the internal short-circuit has occurred is melted by Joule heat generated due to a short-circuit current flowing into the cell 10 in which the internal short-circuit has occurred from the other cells 10 in which no internal short-circuit occurs via the first connecting member 20.
    • 电池模块100包括布置成格栅阵列的多个单元10。 排列成行方向的电池单元10通过第一连接构件20并联连接。沿列方向排列的电池单元10被连接在一起,使得在列方向上彼此相邻的电池单元10串联连接在一起,串联连接 第二连接构件30.当在单元10中的任一个内部发生内部短路时,连接到发生内部短路的单电池10的第一连接构件20由于短路而产生焦耳热而熔化 从其中没有经由第一连接构件20发生内部短路的其他单元10流入其中发生内部短路的单元10的电路。

    • A safety mechanism for a laminate battery. An exterior case (5) consists of two molded sheets (5a) made of laminate sheets, superposed upon one another, and bonded together around the outer edges. The exterior case has a protrusion (10) that communicates with the interior of the exterior case and protrudes outwardly from one side. A safety vent (13) is made up of an exhaust hole (11) formed in at lease one of the two molded sheets (5a) in the protrusion (10), and a valve element (12) making elastic pressure contact with the edge of the exhaust hole (11) to seal it. The safety mechanism does not operate within the range of internal pressure variation during normal use, but operates reliably at a time point when a predetermined valve operating pressure is reached to release a necessary amount of gas to the outside, this valve operating pressure being within the safe range relative to the pressure resistance of the exterior case (5) made of laminate sheets. Also, the safety vent configuration enables a reduction in production cost.
    • 层压电池的安全机构。 外壳(5)由两层叠片构成的两个模制板(5a)组成,彼此叠置并围绕外边缘粘结在一起。 外壳具有与外壳的内部连通并从一侧向外突出的突起(10)。 安全排气口(13)由在突起(10)中的两个模制板(5a)中的至少一个形成的排气孔(11)和与该边缘(10)弹性压力接触的阀元件 的排气孔(11)进行密封。 安全机构在正常使用期间不能在内部压力变化的范围内工作,而是在达到预定的阀操作压力的时间点可靠地操作以将必需量的气体释放到外部,该阀操作压力在 相对于由层合板制成的外壳(5)的耐压性的安全范围。 此外,安全排气构造能够降低生产成本。
