The plurality of batteries (200) may be arranged on the top surface of the base frame (100) inside the predetermined region (R). The plurality of batteries (200) may include a plurality of types of batteries (200N, 200S) having different shapes of cross-sectional footprints (F). At least one portion (RCP) of the circumference of the predetermined region (R) may extend obliquely. At least one portion (FCP) of the circumference of the cross-sectional footprint (F) of a special type battery (200S), which is at least one type of the plurality of types of batteries (200), may extend obliquely along the at least one portion (RCP) of the circumference of the predetermined region (R).
