To increase an effect of absorbing an impact load from a vehicle front side. A vehicle-body structure includes a left-side suspension support member supporting a front suspension, a center frame disposed higher than and away from a floor panel at a vehicle-width-direction central portion of an occupant space and extending in a vehicle front-rear direction, a left-side front frame connected to a front portion of the center frame and extending to the left-side suspension support member, a right-side front frame connected to the front portion of the center frame and extending to a right-side suspension support member, and a connection member that connects the floor panel and at least one of a rear portion of the left-side front frame, a rear portion of the right-side front frame, and the front portion of the center frame.

A floor anchor for supporting a webbing waist portion of a seat belt mechanism is supported by a seat rail that is a frame member of a seat cushion. The seat rail is supported by a rear floor panel through a fastening panel that is a holding member. An end portion of a battery pack is also supported by the floor panel through the fastening panel.

An energy storage device for a motor vehicle includes a plurality of round cells for electrochemical storage of energy and multiple retaining frames for retaining the round cells. The round cells are secured to opposing retaining frames by their ends. Cell connectors are provided on the retaining frames, which electrically contact the round cells arranged between the retaining frames from the outer sides.

A vehicle floor structure includes: a center floor; a plurality of longitudinal members attached to a bottom surface of the center floor; and a battery assembly having a battery case disposed under the center floor and a through bolt passing through the battery case, wherein the through bolt is vertically aligned with respect to at least one longitudinal member among the plurality of longitudinal members, and the through bolt is joined to the at least one longitudinal member.

A battery pack to be mounted on a vehicle includes a battery, a passage unit, a gas pump, a first valve, and an arithmetic and control unit. The passage unit is disposed on at least one of sides of the battery. The passage unit allows fluid to flow through an inside of the passage unit. The gas pump operates with electric power of the battery. The gas pump draws gas in the inside of the passage unit. The first valve shuts off a fluid passage through which the gas is to be supplied to the inside of the passage unit. The arithmetic and control unit controls the gas pump and the first valve, and performs a first temperature regulating process. The process includes driving the gas pump while the first valve is not shut off, and then drawing the gas from the inside of the passage unit.

An electrically driven vehicle includes a floor panel, a tunnel section, an electrical storage device, and an electric power line. The tunnel section is formed in a vehicle forward/rearward direction in a central portion of the floor panel in a vehicle width direction. The electrical storage device is disposed behind the tunnel section of the vehicle above the floor panel. The electric power line is disposed below the tunnel section and connected to the electrical storage device. The tunnel section has an opening portion formed in a rear end portion of the tunnel section located in front of the electrical storage device of the vehicle and through which the electric power line is inserted.

An electric vehicle includes: a power storage device; a floor member disposed on a bottom portion of a vehicle body; and a cover member fixed to the floor member and forming a storage space for the power storage device between the floor member and the cover member. The electric vehicle includes: an intake port introducing air in a passenger compartment into the storage space; and an exhaust port exhausting air having been heat-exchanged with the power storage device in the storage space into the passenger compartment. The exhaust port is composed of the floor member and the cover member.

A vehicle body structure includes a front floor panel provided on a vehicle front side and a rear floor panel provided at the rear of the front floor panel. The front floor panel is positioned higher than the rear floor panel. A first battery arrangement portion is provided long in a vehicle front-rear direction at a center portion of the front floor panel in the vehicle width direction. A second battery arrangement portion is provided outside the first battery arrangement portion in a vehicle width direction below the front floor panel. An upper portion of the first battery arrangement portion is positioned higher than an upper portion of the second battery arrangement portion.

The invention relates to an electric car with (a) a first axle (12), (b) a second axle (14), (c) an electric motor (18) for driving at least one of the axles, which has an electric motor overall height (h.sub.M)t, and (d) a battery (22) for supplying the electric motor (18) with electrical energy, which has a battery overall height (h.sub.B), wherein (e) the electric motor overall height (h.sub.M) corresponds to the battery overall height (h.sub.B). According to the invention, (f) the electric motor (18) is composed of at least two electric motor modules (38.1, 38.2) and (g) the electric motor modules (38.1, 38.2) are arranged one behind the other in relation to a motor rotational axis (D.sub.18); (h) the electric motor modules (38.1, 38.2) have a common rotor shaft (4) or coupled rotor shafts (41); (i) the electric motor (18) and the battery are arranged at the same height; and (j) a battery mass centre of gravity (S.sub.22) of the battery lies in a central third (Q) between the axles (12, 14).

An open cabin vehicle is equipped with a fuel cell unit having a hydrogen tank for storing hydrogen to be used as fuel and has a simple structure. An upper end of each of a hydrogen tank, a fuel cell stack, and a hydrogen supply pipe is located farther upward than a floor in a state in which the hydrogen tank, the fuel cell stack, and the hydrogen supply pipe are disposed in a fuel-cell-unit arrangement space which is provided below a space being present farther backward than at least a part of the floor in a vehicle-body inner space, and which borders the vehicle-body inner space, thereby being connected to a vehicle-body outer space which is a space around the open cabin vehicle, via the vehicle-body inner space.
