Abstract: The battery is sealed by a sealing member including a safety valve for exhausting the gas generated in the battery to the outside of the battery when the pressure in the battery is increased. A part of the sealing member is formed of a member having a melting point lower than that of high-temperature gas generated in the abnormal time and having a ratio of an area of an opening of the battery case to an area of a gas exhaust hole is 3.0×10−5 or more and 9.1×10−3 or less.

Abstract: Battery pack includes the following elements: large number of battery cells; lower holding member provided to hold the lower parts of large number of battery cells aligned by battery holding parts, and having lower openings for exposing the negative electrode terminal side of the battery cells; a positive electrode current collecting plate and a negative electrode current collecting plate connected to the corresponding terminals of the battery cells; and holder formed of upper holding member and lower holding member. In holder, upper gas channel for guiding the gas jetted from battery cells to the front side is formed. Inside holder, lower gas channel is formed on the periphery of the large number of battery cells. In holder, exhaust port is formed. In upper holding member, a communication hole for allowing communication between upper gas channel and lower gas channel is formed.

Abstract translation: 电池组包括以下元件：大量电池; 下保持构件，其设置成保持由电池保持部对准的大量电池单元的下部，并且具有用于暴露电池单元的负极端子侧的下开口; 连接到电池单元的相应端子的正极集电板和负极集电板; 和由上保持构件和下保持构件形成的保持器。 在保持器中，形成用于将从电池单元喷射的气体引导到前侧的上部气体通道。 内部保持器中，在大量电池单元的周围形成下部气体通道。 在支架中形成排气口。 在上部保持构件中，形成用于允许上部气体通道和下部气体通道之间的连通的连通孔。
