Abstract: A battery module includes a plurality of battery sets in which first unit cells and second unit cells are adjacent to each other. In the first unit cell, a positive electrode terminal and a negative electrode terminal are oriented and extend in a first direction from a first end portion of a first main body. In the second unit cell, a positive electrode terminal and a negative electrode terminal are oriented and extend in a second direction opposite to the first direction from a first end portion of a second main body. Then, in the battery set, at least a part of the first main body and the second main body overlap and are in contact with each other. Further, a heat conductive material that conducts heat from the first unit cell or the second unit cell is in contact with the battery set.

A battery system 32 includes a battery module 30 having a plurality of unit cells 40. The battery module 30 is individually provided with a first cooling part 36 through which a first cooling medium 62 flows, by which heat of the unit cells 40 in the battery module 30 is transferred. The unit cells 40 in the battery module 30 are simultaneously cooled by the first cooling part. The battery system 32 includes a second cooling part 78 that discharges a second cooling medium 80 into a casing 34 that houses the battery module 30. The battery module 30 in the casing 34 is simultaneously cooled by the second cooling part.

Abstract: Provided is a locomotive performance testing apparatus capable of testing the locomotive performance of a test subject while keeping the test subject at a suitable position on a treadmill. According to the locomotive performance testing apparatus (1), a robot (2) is moving its legs (22) toward a second direction on a plurality of endless belts (11) which are rotationally driven by a plurality of motors (12), respectively. In this situation, a positional deviation or the like of the robot (2) from a first desired position in a first direction different from a second direction is determined as a first deviation. Moreover, motions of the plurality of motors (12) are individually controlled to offset the first deviation.
