A hybrid vehicle may include a battery and a fuel tank, wherein the battery is mounted in a space defined under a body floor, on which a double seat is disposed, and the fuel tank is disposed over an upper end portion of a rear-wheel suspension and a rear of a body cross member.

To sufficiently improve the distortion stiffness of a vehicle body in a case in which no floor tunnel largely bulging upward from a floor panel is provided. A vehicle-body structure includes a floor panel constituting a floor of an occupant space including a seat on which a passenger is to sit, a cross member provided at a rear portion of the floor panel and extending in a vehicle width direction, a center frame disposed to be higher than and away from the floor panel at a vehicle-width-direction central portion of the occupant space and extending in a vehicle front-rear direction, and a connecting member connecting the cross member and a rear portion of the center frame.

The invention generally relates to an electric vehicle having an electric motor and a pack for storing energy, said vehicle configured having: at least two passenger seats, including a first seat, and a second seat, positioned behind the front seat and configured to face rearward; and the pack having: a lateral module configured to extend perpendicularly to the longitudinal axis of the vehicle between the first seat and the second seat.

An object of the present invention is to provide a battery protection member capable of achieving both securement of a capability to allow a passenger to reside in a vehicle and protection of a battery at the same time. According to one aspect of the present invention, a battery protection member includes a hollow-shaped battery containing frame extending in a vehicle lateral direction of the vehicle. The battery containing frame includes a surface where a seat occupied by a driver is disposed on an outer surface side thereof. The battery containing frame is configured to contain the battery on an inner surface side thereof.

A vehicle power source system includes: a high-voltage battery; a high-voltage system equipment having a DC-DC converter and a charger; and a cooling circuit having a high-voltage battery cooling unit for cooling the high-voltage battery, a DC-DC converter cooling unit for cooling the DC-DC converter, and charger cooling unit for cooling the charger. In the cooling circuit, the DC-DC converter cooling unit and the charger cooling unit are disposed in parallel on a downstream side of the high-voltage battery cooling unit.

An in-vehicle battery attachment structure is to be disposed under a rear seat of the vehicle. The in-vehicle battery attachment structure includes at least one left battery module and at least one right battery module, a housing case, and a battery frame. The at least one left battery module and the at least one right battery module are to be disposed apart from each other in a left-right direction of the vehicle. The housing case houses the at least one left battery module and the at least one right battery module. The at least one left battery module, the at least one right battery module, and the housing case are attached to the battery frame in a suspended state. The battery frame is to be fixed to a vehicle body of the vehicle. The rear seat is attached to the battery frame.

A framework structure of a body-on-frame vehicle, the framework structure comprises a first framework, a second framework, and a battery. The first framework includes: a pair of left and right side rails extending in a vehicle body front-and-rear direction, a first cross-member and a second cross-member, both extending in a vehicle body left-and-right direction and linking the side rails. The second framework is structured in a rectangular shape in plan view and includes: a front cross portion and a rear cross portion that are formed in chamber shapes and extend in the vehicle body left-and-right direction, and a left side cross portion and a right side cross portion that are formed in chamber shapes and extend in the vehicle body front-and-rear direction. The battery is disposed in a cavity surrounded by the first framework and the second framework.

A vehicle power supply system includes: a plurality of battery modules each having a plurality of high-voltage batteries; a case for accommodating the plurality of battery modules; and a cooling circuit having a radiator, a cooling pump, a plurality of battery cooling units for cooling the plurality of battery modules, the case being disposed below a floor panel. In the cooling circuit, the plurality of battery module cooling units are disposed in parallel; and a branch portion which is provided to an upstream side of the plurality of battery module cooling units and a merging portion which is provided to a downstream side of the plurality of battery module cooling units are provided inside the case.

A fuel cell vehicle includes a high voltage apparatus for a fuel cell, a compressor for an air conditioner disposed under the high voltage apparatus for the fuel cell and constituting a module integrated with the high voltage apparatus for the fuel cell, and a power control unit separated from the high voltage apparatus for the fuel cell, disposed at a vehicle body over the compressor and configured to control an operation of a motor. The compressor and the high voltage apparatus for the fuel cell are connected by a single power wiring.

A vehicle adapted to improve cooling capacity and a carrying capacity of two types of batteries and implementing miniaturization of a system including the batteries, a battery unit and a battery carrying method of the vehicle are provided. The vehicle (1) includes a first power storage element (11), a second power storage element (12) with output weight density superior to that of the first power storage element (11), a motor (9) driven by at least one of electric powers of the first and second power storage elements (11) and (12), where the first and second power storage elements (11) and (12) are disposed outside a passenger compartment (5) and disposed under the passenger compartment (5) along a vertical direction, and the second power storage element (12) is disposed at a front end along a front and rear direction of the vehicle compared to the first power storage element (11).
