The present disclosure is to provide a body structure of an eco-friendly vehicle for supporting a battery including an intermediate floor panel composed of a first intermediate floor panel connected to a center floor panel and a second intermediate floor panel connected to a rear floor panel; a rear cross reinforcement panel and an extension reinforcement member mounted on a bottom portion in a battery seating area of the intermediate floor panel; and an intermediate floor upper panel mounted on a front portion in the battery seating area of the intermediate floor panel.

A first body cross-member is disposed on body mounts and fixed to the body mounts through outer brackets and mount bolts that are fastening members. A battery and a cooling blower that is a battery accessory provided on an outer side of the battery in a vehicle width direction are installed on a vehicle body, between a pair of rockers. The rockers have a closed cross-sectional structure, and a brace that is a reinforcing member is housed in a battery flanking portion of each rocker that is a portion corresponding to the cooling blower in position in a vehicle front-rear direction.

A battery pack assembly includes a battery pack, a first elongated terminal connector, a second elongated terminal connector, and a biasing member. The battery pack includes a plurality of battery cells each having a terminal. The first elongated terminal having a plurality of first recesses. The second elongated terminal having plurality of second recesses. The first elongated terminal connector and the second elongated terminal connector movable between an engaged position and a disengaged position. The biasing member extends between the first elongated terminal and the second elongated terminal, and the biasing member biases the first elongated terminal and the second elongated terminal towards the engaged position. In the engaged position, the plurality of first recesses are engaged with the terminals of the plurality of battery cells and the plurality of second recesses are engaged with the terminals of the plurality of battery cells.

Provided is a vehicle which includes an air intake grille for taking in air in a passenger compartment, an electric device, a case for accommodating the electric device, and an intake duct for connecting the intake port provided in the case and the air intake grille, where, when the air intake grille is divided into a region close to the intake port and a region far from the intake port in a vehicle width direction, the sum of opening areas of flow rate adjusting windows located in the region far from the intake port is larger than the sum of opening areas of flow rate adjusting windows located in the region close to the intake port.

A battery system of a vehicle is provided and includes a battery module assembly (BMA) formed by overlapping a plurality of battery modules along a first direction, a cooling fan installed to be aligned along the first direction on one side of the BMA and configured to discharge air cooling the BMA while passing therethrough, a low voltage battery installed to be aligned along the first direction on the other side of the BMA, a power relay assembly (PRA) aligned along a second direction perpendicular to the first direction and installed adjacent to the low voltage battery, and a battery management system (BMS) aligned along a third direction perpendicular to the first direction and the second direction and installed adjacent to the low voltage battery and the PRA.

A battery pack mounting system includes, among other things, a bracket having a first connection flange configured to connect to a vehicle structure, a second connection flange configured to connect to a battery pack, and a spanner portion spanning from the first connection flange to the second connection flange. The bracket includes one or more openings that segment the bracket into at least a first section and a second section. Each of the openings extends into both the spanner portion and the first connection flange.

Power supply device includes: a pair of end plates disposed on both ends in a stacking direction of battery stack constituted by stacking a plurality of secondary battery cells; and a plurality of fastening members fastening the pair of end plates together. Each of fastening members includes fastening main face having a flat plate shape and locking block fixed to a corner of fastening main face Each of end plates is formed with step that locks locking block while being fastened by fastening members, and has end plate screw hole opened near step. Each of fastening members has fastening side through hole opened so as to align with end plate screw hole while having each of end plates fastened, and has a fixing region fixing locking block to fastening main face disposed in a direction further away from each of end plates than fastening side through hole.

A hybrid vehicle having an improved arrangement structure is provided. The hybrid vehicle includes a fuel tank which provides fuel to an engine, and is disposed in a first area which is recessed upward from the under surface of the exterior of a vehicle body. A battery provides an electric driving force to a vehicle, and is disposed in a second area which is recessed downward between the bottom of the interior of the vehicle body and a rear seat. The first area is disposed further forward than the second area in a longitudinal direction of the vehicle body.

In a cooling structure for a battery pack, a case bottom wall of a first battery case is divided into left and right case bottom walls. A first cooling medium jacket includes left and right first cooling medium jackets formed respectively in the left and right case bottom walls. Left ends of the left first cooling medium jacket and second cooling medium jacket are made to communicate with each other via a left cooling medium passage. Right ends of the right first cooling medium jacket and second cooling medium jacket are made to communicate with each other via a right cooling medium passage. Accordingly, it is possible to simplify the structure of a cooling medium passage for supplying cooling medium to a cooling medium jacket of battery cases on two levels.

A mounting structure for a power storage device includes: a power storage device including a power storage stack and a housing case; a floor member; and a rear bracket. The housing case includes a lower case having a rear wall, and an upper case. The floor member is provided with an attachment portion for attaching the rear bracket. The rear bracket includes a front end portion and a rear end portion that is attached to the attachment portion. The power storage stack is disposed inside the housing case to provide a gap between the power storage stack and the rear wall. The front end portion of the rear bracket is fixed to the rear wall to be located between an upper surface and a lower surface of the power storage stack in an up-down direction.
