The electric snowmobile includes a body frame, a driver's seat, an electric motor, a ski, a track mechanism, a battery, a cooling unit that cools fluid at least in accordance with outside air, a first heat exchange unit that performs heat exchange between the battery and the fluid, a second heat exchange unit that performs heat exchange between the electric motor and the fluid, a first flow path for delivering the fluid cooled in the cooling unit to the first heat exchange unit, a second flow path for delivering the fluid cooled in the cooling unit to the second heat exchange unit, and a third flow path for delivering the fluid heat-exchanged in the first heat exchange unit and the fluid heat-exchanged in the second heat exchange unit to the cooling unit.

A vehicle includes: a rotating electrical machine configured to drive the vehicle; a high-voltage power source configured to supply electricity for driving the rotating electrical machine; main and backup low-voltage power sources; a normal load configured to operate on the electricity supplied from the main low-voltage power source; a critical load configured to operate on the electricity supplied from the backup low-voltage power source; and a floor panel. The critical load includes an auxiliary load for controlling, braking, steering, or acquiring external information of the vehicle. A central tunnel extending in a central part of the vehicle in the vehicle width direction along the vehicle length direction is formed in the floor panel. The low-voltage power sources are placed right above the floor panel. One of them is placed to one side of the central tunnel in the vehicle width direction, and the other one the other side.

Disclosed is an electric vehicle having four wheels and a body having a cockpit defined therein, the cockpit containing a single seat and being closable to form an enclosure around the seat. The body has a front bumper having a width that is greater than a front track width of the vehicle. A width of the vehicle is between 1200 mm and 1600 mm, and a height of a centre of mass of the vehicle above a ground surface on which the vehicle is disposed is less than a third of the width of the vehicle. The electric vehicle may be suited for use in urban environments, and may provide benefits in terms of improved safety and maneuverability.

A frame structure for maintaining energy storage devices of a vehicle in position which is deformed in a controlled way in the event of a side-impact, in such a way to avoid deforming into the location of the vehicle seats. The proposed frame structure is adapted to deform controllably in a centre position align with a location between the vehicle seats. In this way are occupants of the vehicle kept safe since no or less deformation occur in the vehicle seat location. The above advantages are provided by that lateral support members of the frame includes a deformation zone adapted to deform in response to a lateral force exerted on the lateral support member. The deformation zone is located such that, when the frame structure is installed in the vehicle, the deformation zone is aligned with a location between seats of the vehicle.

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.

A fuel cell electric vehicle includes: a motor, a fuel cell stack and an integrated controller, which are accommodated in a PE room provided in a front of a vehicle body; a battery assembly including a high-voltage battery electrically connected to the motor and the fuel cell stack, and a low-voltage battery for supplying electric power to a vehicle electrical part; an IDC that is mounted between the PE room and the battery assembly, and electrically connects the high-voltage battery to the motor and the fuel cell stack; and a plurality of hydrogen tanks that is mounted at a rear of the battery assembly and below the vehicle body. In particular, the battery assembly is mounted at a rear of the PE room and below the vehicle body, and the IDC converts power of the high-voltage battery to be supplied to the low-voltage battery.

Proposed is an electric mobility vehicle in which material cost is reduced by simplifying the structure for cooling a battery module and a sealing structure. The electric mobility vehicle is capable of increasing sealing performance since an inflow path of moisture from outside is reduced, and securing desired battery cooling performance.

A battery-pack mounting structure for a vehicle, includes: a lower casing surrounding a lower side of a battery pack; an upper casing surrounding an upper side of the battery pack, and coupled to the lower casing to form a battery casing coupled to a bottom side of a vehicle body panel; a casing gasket provided in a coupling portion between the lower casing and the upper casing and implementing a sealing between the lower casing and the upper casing; an inlet gasket provided in a portion where an inlet provided in the upper casing is connected to the vehicle body panel and implementing a sealing between the inlet and the vehicle body panel; and an outlet gasket provided in a portion where an outlet provided in the upper casing is connected to the vehicle body panel and implementing a sealing between the outlet and the vehicle body panel.

An apparatus for providing a secondary power source for an electric vehicle, the apparatus attachable to the electric vehicle and having at least one secondary electrical power storage unit for storing electrical energy for delivery to the electric vehicle as required to replace the primary power source, a power connection assembly to connect the at least one secondary power source to the electric vehicle and a control system to control supply to the electric vehicle.

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.
