A battery module is provided comprising a plurality of battery cells and a housing having an internal space in which the plurality of battery cells are accommodated. The housing is at least partially formed of a plate member which is connected with the internal space. The plate member forms a flame or gas path which in an event of a battery cell malfunction generating a flame or gas is configured to discharge the generated flame or gas externally of the housing.

In a detection module to be mounted on a unit cell group formed by electrically connecting adjacent electrode terminals of a plurality of unit cells including positive and negative electrode terminals by busbars, a plurality of fuse units each configured such that a busbar connection terminal for detecting a state of the unit cell by being connected to the busbar, a wire connection terminal to be connected to an end part of a wire and a fuse for connecting the busbar connection terminal and the wire connection terminal are integrally assembled and accommodated in a housing made of synthetic resin are held in a holding member made of synthetic resin.

A connector assembly for electrically connecting poles of two adjacent battery cell. The connector assembly comprises an electrically conductive bus bar having a first connection area and a second connection area distal from each other, electrically conductive pole-mating components having a pole-mating face and a bar-mating face, and fastening components for attaching the electrically conductive bus bar and one of the pole-mating components to one of the poles of the two adjacent battery cells. The pole-mating faces of the pole-mating components are adapted for mating the poles the battery cells. The bar-mating faces of the pole-mating components are adapted for mating with the connection areas. The bar-mating faces and the connection areas have complementary concave/convex arched shape for optimizing contact surface over a range of relative positioning of the two adjacent battery cells.

A battery module includes a plurality of battery cells arranged in one direction, a pair of end plates at outsides of respective outermost battery cells among the plurality of battery cells, a pair of end blocks between the end plates and the respective outermost battery cells, and a protection device in at least one end block of the pair of end blocks.

The disclosure relates to a technical field of batteries, and in particular, relates to a battery pack. The battery pack includes a box body, a beam, a battery apparatus, and an electrical support base. The beam is disposed in the box body. The battery apparatus is disposed in the box body, and an electrical conductor is disposed on the battery apparatus. The electrical support base is disposed on the beam. The electrical conductor extends from the battery apparatus to the electrical support base and is connected to the electrical support base.

A wiring module includes a busbar for connecting between electrode terminals, an external connection busbar to be connected to an external terminal, a resin protector including a first holding portion for holding the busbar and a second holding portion for holding the external connection busbar and a main cover for covering the first holding portion. The main cover includes a first auxiliary cover for covering the second holding portion and a second auxiliary cover connected to the first auxiliary cover via a hinge portion. The first auxiliary cover is provided with an interfered portion for interfering with an interfering portion of the second holding portion as the main cover is mounted on the resin protector, and the first auxiliary cover is automatically rotated and arranged at a predetermined position by the interference of the interfered portion and the interfering portion.

A battery module includes a busbar. The busbar that electrically connects electrode leads protruding from an electrode assembly to the busbar. The battery module also includes a busbar frame accommodating the busbar. The busbar is fixed to the busbar frame. The battery module also includes a connection busbar connected to the busbar and a connection bolt connecting the busbar and the connection busbar together. The busbar includes a first screw thread, and the connection bolt is fixed to the first screw thread.

Proposed is a battery pack. The battery pack includes a battery module in which an internal terminal is exposed at an opening part, and a flame blocking unit which is connected to the internal terminal via the opening part and which transmits electric power of the internal terminal to the outside, the flame blocking unit covering the opening part so that a flame generated inside the battery module is blocked from being emitted. The battery module may include a battery assembly including a plurality of battery cells, a busbar assembly including the internal terminal which is connected to the battery assembly and which transmits electric power, and a casing which accommodates the battery assembly and the busbar assembly therein and in which the opening part is formed. By this configuration, thermal runaway of the battery module may be blocked or delayed, so stability of the battery pack may be increased.

A copper bar protection structure (10) includes an upper housing (11) and a lower housing (12) that are engaged with each other. A receiving groove (14) is provided on each of engagement surfaces (15) of the upper housing (11) and the lower housing (12). The two receiving grooves (14) are combined into a copper bar accommodating space. A phase change material layer (30) is laid on an inner wall (13) of the receiving groove (14). The copper bar (20) is wrapped by the phase change material layer (30) when the copper bar accommodating space accommodates a copper bar (20).
