摘要： Provided is a battery module configured so that cooling performance can be improved. The battery module includes multiple battery cells 10 stacked on each other, a spacer 12 provided at an end portion of each battery cell 10, and heat transfer plates 20 each of which has a heat absorption portion 20a arranged between the multiple battery cells 10 stacked on each other to absorb heat from the battery cells 10 and a heat dissipation portion 20b dissipating the heat absorbed by the heat absorption portion 20a to the outside. The heat dissipation portion 20b is bent relative to the heat absorption portion 20a, and is exposed through between the battery cells 10 to contact the spacer 12. The spacer 12 includes contact portions 126 having contact surfaces 260 contacting the heat dissipation portion 20b, and a positioning portion 127a having a surface 270 facing a direction opposite to that of the contact surface 260 and defining the position of the spacer 12.

摘要： Provided is a battery module configured so that connection among tabs and a bus bar stacked on each other is properly made. The battery module includes: multiple battery cells 10 each of which has tabs 101, 102; bus bars 152, 153 electrically connecting the battery cells to each other; and an electrical insulating bus bar holder 150 holding the bus bars 152, 153 such that the bus bars 152, 153 are arranged apart from each other in parallel. The bus bar holder 150 has, in regions adjacent to the bus bars 152, 153, slit openings 156b to 156e through which the tabs 101, 102 are drawn. The bus bars 152, 153 include plate-shaped tab connection portions standing on an outer peripheral surface of the bus bar holder 150 and joined to the tabs 101, 102.
