An electric vehicle includes plurality of batteries accommodated in a rear portion of a battery box, and an electric part is accommodated in an electric part accommodating chamber provided in a front portion of the battery box. Cooling air supplied from a cooling fan to the rear portion of the battery box cools the batteries having a large thermal resistance, while being passed through a first cooling air passage around outer peripheries of the batteries at a low flow rate. A second cooling air passage having a smaller sectional area than that of the first cooling air passage is provided below the electric part accommodating chamber, and cooling fins protruding downwards from the electric part are exposed within the second cooling air passage. The second cooling air passage extends continuously the first cooling air passage in a downstream direction of airflow, so that cooling air which has first cooled the batteries then cools the electric part having a smaller thermal resistance, while being passed through the second cooling air passage at a higher flow rate than that in the first cooling air passage.

The present invention relates to all terrain vehicles having at least a pair of laterally spaced apart seating surfaces. More particularly, the present invention relates to trail compliant side-by-side all terrain vehicles.

A method of thermal management for a thermal management system in a vehicle includes the steps of selecting a thermal management function. The method also includes the steps of adjusting a temperature within the thermal management system using the thermal management function and using the adjusted temperature within the thermal management system to control a temperature within an occupant compartment of the vehicle.

An integrated assembly includes a bumper energy absorber section with crush lobes for abutting a bumper beam, an upper air shutter section with subassembled shutter members movable between closed and open positions, a first actuator mechanism for moving the shutter members between positions, an upper fascia support section with upper leg crush lobe therein above the upper air shutter section, a lower air shutter section with subassembled lower shutter members movable between closed and open positions, a second actuator mechanism for moving the lower shutter members between the positions; and a lower leg energy absorber section attached below the lower air shutter section and configured to abut (or replace) a face of a secondary pedestrian impact bar. The shutter members may be molded to a shutter frame using over molding technology rather than separately, manually assembled.

In a structure for mounting a battery pack on a vehicle, since a recess portion, into which a cross member is fitted, is formed on an upper face of a battery case so as to extend in a vehicle width direction, it is possible to mount the battery pack on a vehicle body without interfering with the cross member, and it is unnecessary to raise the position of the cross member or form a cutout in the cross member, thereby enabling a balance to be achieved between the capacity of a vehicle compartment and the strength of the cross member while ensuring a sufficient minimum ground clearance for the battery pack and preventing a battery from becoming wet. Furthermore, since the recess portion is formed on the upper face of the battery case, a cooling passage disposed beneath the battery is not narrowed, thus ensuring the battery cooling performance.

A heat exchanger integrated into an electric vehicle's battery pack enclosure is provided, where the heat exchanger conduits are mechanically and thermally coupled to the inside surface of the enclosure base plate and where the battery pack enclosure is mounted such that ambient air flows over the outside surface of the enclosure base plate during vehicle motion. A thermal management system is coupled to, and controls operation of, the integrated battery pack heat exchanger such that in a first operational mode the heat exchanger is thermally coupled to the batteries within the battery pack, and in a second operational mode the heat exchanger is thermally decoupled from the batteries within the battery pack.

A dual mode, thermal management system for use in a vehicle is provided. At a minimum, the system includes a first coolant loop in thermal communication with a battery system, a second coolant loop in thermal communication with at least one drive train component (e.g., electric motor, power electronics, inverter), and a dual mode valve system that provides means for selecting between a first mode where the two coolant loops operate in parallel, and a second mode where the two coolant loops operate in series.

A motor vehicle is equipped with an outside air introduction assembly 104 functioning to introduce the outside air into a radiator 92 in an engine cooling system during driving, as well as with an outside air introduction assembly 114 functioning to introduce the outside air into an engine 22 during driving. The motor vehicle is also equipped with shutter plates 106 capable of regulating the amount of the outside air to be introduced by the outside air introduction assembly 104, as well as with shutter plates 116 capable of regulating the amount of the outside air to be introduced by the outside air introduction assembly 114. The shutter plates 106 and the shutter plates 116 are individually actuated and controlled to increase the amount of the outside air to be introduced by the outside air introduction assembly 104 and the amount of the outside air to be introduced by the outside air introduction assembly 114 with an increase of temperature of cooling water detected as a cooling water temperature Twe in the engine cooling system. Such actuation and control assures the adequate cooling performances to cool down the cooling water by the radiator 92 and to cool down the engine 22.

A shutter for closing openings with pivotal shutter elements, the rotational axes of which are arranged parallel to each other. Better sealing is achieved in that the shutter elements consist of at least two wings that are solidly joined together and arranged almost parallel to each other. The wings of the shutter elements are oriented substantially parallel to an imaginary plane of the opening, thus closing it on both sides, in a first position and substantially normal to the plane of the opening, thus clearing said opening, in a second position.

A grill shutter unit comprises a shutter unit provided in back of a traveling-air introductory port formed at a front end of a vehicle body and including shutter members, and a traveling-air guide member including a guide frame portion provided at an outer peripheral edge portion of the shutter unit and a seal portion provided to extend forward continuously from a front end of the guide frame portion and be made from soft synthetic resin having more flexibility than the frame portion, wherein the grill shutter unit is configured such that when the shutter members are closed, a seal portion of the traveling-air guide member is pressed against an outer peripheral wall face of the traveling-air introductory port by pressure of traveling air shut off by the shutter members closed.

A power device for a vehicle includes a plurality of batteries, a case accommodating the batteries, a blower for forcibly supplying air to the batteries accommodated in the case, thereby cooling them, and a temperature sensor for coming in contact with a surface of the battery to detect a temperature of the battery. A thermal portion for detecting the temperature of the battery of the temperature sensor includes a thermal element to be thermally coupled to the surface of the battery, and a heat insulating material having a cushioning property to be elastically compressed which serves to thermally insulate the thermal element provided on the surface of the battery from the cooling air, and the thermal element is isolated from the cooling air supplied forcibly by means of the heat insulating material having the cushioning property, thereby detecting the temperature of the battery.

A vehicle-mounted generator is powered by relative wind produced by the combination of ambient wind and motion of the vehicle, or by movement of water when mounted on the hull of a water-borne vehicle. A rigid cylindrical housing forms an enclosed interior chamber. Wind asymmetrically enters the chamber through an inlet located on one side of a central longitudinal drive shaft, and exits through an outlet located at the top of the housing. A spiraling parabolic deck forms a floor of the interior chamber, and spirals around the central longitudinal shaft from the bottom of the housing to the outlet at the top. A turbine mounted on the drive shaft within the outlet converts energy of the exiting wind to mechanical energy. An electrical generator converts the mechanical energy into electrical energy for recharging a battery or powering an electric motor.
