Abstract: A battery pack includes a battery case, battery cells, and coolant jackets. A cell joined body formed of the battery cells joined in a row and the coolant jacket are alternately arranged in surface contact with each other in a first direction. Each coolant jacket is connected to coolant circulation pipes provided on both sides in a second direction. At least apart of the coolant jackets is a reinforcing plate-type coolant jacket configured such that upper parts of both end parts in the second direction of the reinforcing plate-type coolant jacket are extended and are joined to upper parts of end plates of the battery case while avoiding the coolant circulation pipes to enhance a rigidity of the battery case.

Abstract: A battery pack includes a battery case, battery cells, and coolant jackets. The coolant jacket includes two thin plates having plasticity that are surface-joined to each other, and a coolant inlet, a coolant passage, and a coolant outlet that are formed as gap portions. The battery cell and the coolant jacket are alternately arranged in surface contact with each other in the battery case. By flowing a non-compressed fluid at a predetermined pressure into the coolant passage of the coolant jacket to expand the coolant jacket by plastic deformation, the battery cells and the coolant jackets are clamped and fixed between two end plates.

Abstract: A battery module includes: a stacked body in which a plurality of secondary batteries are stacked; and a side restraint member which faces a first surface of the stacked body, and which extends in a stacked direction of the stacked body. The first surface is a surface in a vertical direction with respect to a lower surface of the stacked body, and is a surface along the stacked direction, and the first surface and the side restraint member are joined with each other by a joining member.

Abstract: A virtual guide sensor processing unit of an automatic guided vehicle (AGV) computes the position of a virtual guide tape on the basis of the position of the AGV which a vehicle body coordinate value calculation processing unit has computed, and virtual guide tape layout data. A guide sensor switching processing unit outputs to a vehicle body deviation degree calculation processing unit the position of a magnetic guide tape which a magnetic guide sensor has detected, or the position of the virtual guide tape which the virtual guide sensor processing unit has computed.
