Abstract: A vehicle (1) comprises a passenger compartment (2) in which a front seat (32F), a rear seat (32R), and a floor (33) between the front seat (32F) and the rear seat (38R) are provided. A first group (S1) of batteries (3) is mounted under the front seat (32F), a second group (S2) of the batteries (3) is mounted under the floor (33), and a third group (S3) of the batteries (3) is mounted under a rear seat (32R). By setting a height (h2) of the second group (S2) of the batteries (3) to be lower than respective heights (h1, h3) of the first and third groups (S1, S3) of the batteries (3), a battery mounting capacity of the vehicle (1) can be increased without affecting the comfort of the passenger compartment (2).

Abstract: A battery unit (38F) comprising a plurality of batteries (3) and a connection control device (35a, 35b, 36a, 36b, 36d, 36e) which controls electrical connection relating to the battery unit (38F) are provided in a vehicle (1). The battery unit (38F) comprises two groups (S1R, S1L) of the batteries (3) disposed to have a space (G) there-between, and the connection control device (35a, 35b, 36a, 36b, 36d, 36e) is disposed in the space (G). The layout of the connection control device (35a, 35b, 36a, 36b, 36d, 36e) is thereby optimized and the length of a harness (34) can be shortened.

Abstract: A plurality of batteries (3) are disposed under a floor panel (16) of a vehicle (1). A first battery unit (38F) comprising a plurality of batteries (3) stacked in a vertical direction and a second battery unit (38R) comprising a plurality of batteries (3) stacked in a vehicle transverse direction are provided. By arranging a layout of the first battery unit (38F) and the second battery unit (38R) considering the location of an electric equipment (12, 13, 14) to which the batteries (3) supply power as well as the location of passenger seats (32F, 32R), the weight balance of the vehicle (1) in the front-aft direction can be optimized.
