A bus bar includes a wiring pathway made from a conductive material and having bent portions bending at at least two sites of the wiring pathway. The wiring pathway includes members consecutively arranged to form a plate shape. At least two of the members have different characteristics. The members adjacent to each other are connected to each other by laser joining.

Bus bar

A bus bar includes members made from a conductive material and consecutively arranged to form a plate shape defining a wiring pathway. The members adjacent to each other have connection surfaces at which the members adjacent to each other are connected to each other by laser joining. The members adjacent to each other include at least one tolerance buffer between the members adjacent to each other. In the at least one tolerance buffer, the connection surfaces of the members adjacent to each other have different widths.

A bus bar module includes an electric wire routing structure that is attached to an battery assembly including a plurality of battery cells and accommodates a plurality of bus bars in which each electrodes of the battery cells is electrically connected to each other, a plurality of electric wires connected to the battery cells via the bus bars, respectively, an electric wire routing groove formed in the electric wire routing structure and accommodating the electric wires in a pair of side walls, and a lid that is supported by a first side wall via a hinge and covers the electric wire routing groove to block a groove opening.

Bus bar module

A conductor module attachment structure includes a case having a connection conductor, a recessed groove that is provided protrusively on an outer wall of the case, a protector that extends along the recessed groove and is formed into a U-shape and that is configured that an opening portion of a U-groove of the protector is closed by an inner wall face of the recessed groove when the protector is inserted into the recessed groove, a voltage detecting line that is routed in the U-groove of the protector, a voltage detecting terminal that is connected to one end of the voltage detecting line, a terminal retaining portion that is provided on the protector and positions the voltage detecting terminal contactably with the connection conductor.
