Abstract: A vehicle battery unit includes: a battery module where a plurality of battery cells are stacked in a vehicle width direction and a module case for accommodating the battery module. The module case includes: a pair of side plates for holding side surfaces of the battery module; a bottom plate for connecting lower end portions of the pair of side plates to each other; and a pair of end blocks arranged at opposite end portions of the battery module in a stacking direction of the battery module for connecting the pair of side plates to each other. The end block is coupled to an end surface of the side plate in the stacking direction with a coupling bolt, and a thickness of the end block is greater than a thickness of the side plate.

Abstract: A management system that comprises a movement management part that: communicates via communication devices with a plurality of mobile bodies that include autonomous mobile bodies that comprise an autonomous control part that is for autonomous movement; and manages the movement of the plurality of mobile bodies. The autonomous mobile bodies comprise a display device that performs outward-facing display. The movement management part has a superiority determination part that, on the basis of individual information for the plurality of mobile bodies, determines a preference ranking for the movement of the plurality of mobile bodies. The autonomous mobile bodies comprise a display control part that controls the display of the display device in accordance with the preference ranking determined by the superiority determination part.
