摘要： A battery module includes a plurality of secondary batteries, each including an electrode assembly and an electrolyte accommodated in an inner space of an exterior case. The battery module also includes an electrode lead having a body and a plate-shaped head portion. A first end of the body is electrically connected to a positive electrode plate or a negative electrode plate of the electrode assembly, and a second end of the body protrudes outward from the exterior case. The plate-shaped head extends in both directions perpendicular to the protruding direction of the body from the second end. The battery module also includes a bus bar having a plate shape with a slit extending inwardly from one end thereof so as to receive a portion of the body. The electrode lead and the bus bar may be at least partially made of an electrically conductive material.

摘要： A storage battery module includes battery cells, a first member and a second member opposing the first member across a substrate. The first member closes the space between adjacent terminals, and covers an open surface of a housing in a state where the terminals of the battery cells are exposed. The first member is formed of a material having a thermal resistance greater than or equal to a first threshold. The substrate opposing the battery cells across the first member has holes through which the terminals are inserted and a conductor formed therein so as to electrically connect the terminals. The second member opposing the first member across the substrate surrounds the terminals projecting from the holes and covers the substrate with the terminals exposed from the holes. The second member is formed of a material having a thermal resistance greater than or equal to a second threshold.

摘要： A battery module is provided. The battery module includes: first and second bus bars arranged adjacent to each other to electrically connect battery packs adjacent to each other; and a bus bar cover covering and insulating the first and second bus bars from the outside thereof and insulating the first and second bus bars from each other, wherein the bus bar cover includes a hollow portion exposing a coupling hole of the first and second bus bars. Accordingly, sufficient insulation may be secured for the bus bars electrically connecting different battery packs, malfunction and safety accidents caused by the short circuit of the bus bars through which high-voltage charge/discharge currents flow may be prevented, and the insulation structure of the bus bars may be simplified by accommodating different adjacent bus bars together.
