    • The invention provides a battery management system which can reliably and easily manage a power unit of an electric vehicle. The power unit includes a plurality of battery modules. The battery management system includes: a power source for a motor, the power source being constituted by a plurality of battery modules having battery cells; battery module status sensors mounted on the battery modules on the one to one basis, detecting voltages and temperatures of the battery modules; and a control unit judging statuses of the battery modules on the basis of data detected by the battery module status sensors. The battery module status sensors are mutually connected in series by a communication line for transmitting numbering data, and each battery module status sensor assigning itself with an ID code on the basis of ID information received from an upstream battery module status sensor, and transmitting the ID information as well as the ID code to a downstream battery module status sensor. The control unit is connected to the battery module status sensors via the communication line for transmitting the numbering data and a communication line for transmitting various data except for the numbering data, and locates an abnormal battery module on the basis of detection information received via the communication line for transmitting the numbering data and the communication line for transmitting various data except for the numbering data.

    • A single flare tube, and a joint structure of the single flare tube makes a flare of the single flare tube hardly deformed plastically. Additionally, a tensile stress remains lower and is lower when the single flare tube is fastened. A joint structure of the single flare tube coupled with a union includes a single flare tube having a tube and a flare, a flare nut having a thread and a through-hole that receives the tube of the single flare tube, and a union having a thread for coupling with the thread of the flare nut. A width of a narrow inner circumferential groove of a radially outward extending part of the flare is substantially zero and stays substantially zero when the single flare tube is pushed against and coupled with the union by fastening the threads of the flare nut and the union together. Additionally, an internal diameter of the inner circumferential groove preferably is smaller than an external diameter of the tube. Furthermore, a curvature at a radially outer side of an outer corner of the single flare tube (where the tube is connected with the flare) is larger than a curvature at a radially inner side of the outer corner of the single flare tube along a longitudinal cut section of the single flare tube.
    • 单一的耀斑管和单个管道的接头结构使单个火炬管的火炬难以塑性变形。 另外,单个喇叭管被紧固时,拉伸应力保持较低并且较低。 与联合器联合的单个扩口管的接合结构包括具有管和火炬的单个扩口管,具有螺纹的扩口螺母和容纳单个火炬管的管的通孔,以及具有 用于与喇叭螺母的螺纹联接的螺纹。 当通过将扩口螺母和联接器的螺纹紧固在一起而将单个扩口管推压并联接到联接器时,扩口的径向向外延伸部分的窄内周槽的宽度基本上为零并保持基本为零。 此外,内周槽的内径优选小于管的外径。 此外,单个火炬管(其中管与火炬连接)的外角的径向外侧的曲率大于沿着纵向的单个火炬管的外角的径向内侧的曲率 单个火炬管的切割部分。

    • A fuel cell in which the sealed portions formed at the peripheral edges of gas flow passages of a gas separating plate are turned so that they have a U-shaped cross section in the direction of the lamination so as to provide for elasticity. A filling member is filled in the interior of the sealed portions. This gas separating plate is used to respectively form gas flow passages through which different gas fluids are caused to flow so that they are electrochemically reacted in a pair of electrode reacting portions disposed with an electrolyte layer being interposed therebetween. In consequence, the sealed portions provided at the peripheral edges of the gas flow passages deform in accordance with the creep caused in the electrode reacting portions. This enables a balanced, adequate bearing pressure to be kept applied to the electrode reacting portions and the sealed portions, thereby enabling the fuel cell to be operated in an excellent gas sealed state for a long time.
    • 燃料电池,其中形成在气体分离板的气体流路的周边处的密封部分被转动,使得它们在层压方向上具有U形横截面以提供弹性。 填充构件填充在密封部分的内部。 这种气体分离板用于分别形成气体流动通道,不同的气体流体通过该气体流动通道流动,使得它们在设置有电解质层的一对电极反应部分之间电化学反应。 因此,设置在气体流路的周缘处的密封部分根据电极反应部分中产生的蠕变而变形。 由此,能够使电极反应部和密封部保持均匀,适当的轴承压力,能够使燃料电池长期处于良好的气体密封状态。
