Abstract: A management system manages an environment of a predetermined area. In the predetermined area, there are a recognition sensor configured to recognize a surrounding situation and a recognition target to be recognized by the recognition sensor present at a specific position. Three-dimensional map data of the predetermined area include specific space information indicating a specific space that is a space between the specific position and the recognition target. Recognition result information indicates a result of recognition by the recognition sensor present at the specific position. The management system determines whether an object not included in the specific space in the three-dimensional map data is included in the specific space in the recognition result information. The management system detects, as a removal target, the object not included in the specific space in the three-dimensional map data but is included in the specific space in the recognition result information.

Abstract: A battery cooler comprises a refrigerant filling chamber, a refrigerant inflow passage, and a refrigerant outflow passage.
