A cooling structure includes a power storage stack including power storage cells, first and second end plates, a refrigerant supply path for supplying refrigerant, and first paths each provided in a clearance between two of the adjacent power storage cells. The first end plate is configured to form a second path communicating with the refrigerant supply path in a clearance between a first end of the power storage stack and the first end plate. The second end plate is configured to form a third path communicating with the refrigerant supply path in a clearance between a second end of the power storage stack and the second end plate. The power storage stack is cooled to have a temperature distribution in which the power storage cells disposed on the second end side have temperatures higher than the temperatures of the power storage cells disposed on the first end side.

A gas vent duct includes a lower case, an upper case, and a valve element. The valve element includes a shaft at its upper part and pivots on the shaft from a blocking position so that the gas vent pathway communicates with the outside of the vehicle compartment. The blocking position is a position in which the valve element blocks the ventilation pathway. The lower case includes a support supporting the shaft so that the valve element is pivotable. The support covers the shaft from above. A recess is defined by a portion of the inner surface of the upper case that is located above the support, the recess being recessed upward. When the recess and the support are seen from above, at least a part of the support is located within the recess.

Polyphenylene sulfide monofilament and manufacturing method therefor, and package

A polyamide monofilament is characterized in that the abrasion tension thereof when passed through a ceramic guide is 0.3 cN/dtex or less and in that the amount of static electricity generated at the exit of a chromium round bar guide, which is a frictional body, when the polyamide monofilament is passed through the chromium round bar guide, is 300 V or less. This polyamide monofilament and fiber package provide a gauze woven fabric for which tension is low when passing through a thread path guide when warping warp yarn, for which generation of static electricity is suppressed, and which has excellent weaving productivity.

Polyamide monofilament and fiber package thereof

The battery pack is arranged on the first tray. The first tray is arranged on the floor panel of the motor vehicle. The first flange portion is provided on a first peripheral edge. The first peripheral edge is a peripheral edge of the first tray. The battery pack-associated component is arranged on the second tray. The second tray is arranged on the floor panel of the motor vehicle. The second flange portion is provided on a second peripheral edge. The second peripheral edge is a peripheral edge of the second tray. The second flange portion is located above the first flange portion in a vertical direction of the motor vehicle. The second flange portion overlaps with the first flange portion in the vertical direction of the motor vehicle. The first flange portion projects toward the second tray side. The second flange portion projects toward the first tray side.

Motor vehicle

A vehicle includes a motor serving as a driving source for running the vehicle, and a high-power assembled battery and a high-capacity assembled battery each capable of supplying an electric power to the motor and placed in a luggage space. The high-power assembled battery is capable of charge and discharge with a current relatively larger than that in the high-capacity assembled battery. The high-capacity assembled battery has an energy capacity relatively larger than that of the high-power assembled battery and has a higher dependence of battery characteristic on temperature than that of the high-power assembled battery. The high-capacity assembled battery is placed over the high-power assembled battery in the vehicle.

Vehicle

A vehicle has a motor and an engine each serving as a driving source for running the vehicle, and assembled batteries each capable of supplying an electric power to the motor. The assembled batteries include a high-power assembled battery and a high-capacity assembled battery. The high-power assembled battery is capable of charge and discharge with current relatively larger than that in the high-capacity assembled battery, and the high-capacity assembled battery has energy capacity relatively larger than that of the high-power assembled battery. In running of the vehicle using output from the motor with the engine stopped, the high-capacity assembled battery supplies more electric power to the motor than that in the high-power assembled battery. The high-power assembled battery is placed in a vehicle-inside space accommodating a passenger or baggage, and the high-capacity assembled battery is placed in a vehicle-outside space located on an outer face of a vehicle body.

A vehicle having a battery mounted thereon is provided. The battery includes a cell group having a plurality of cells, each of the cells including an electrolytic solution and a power-generating element within a case of cylindrical shape, and a holding member holding each of the cells in a diameter direction of the cell, wherein the cell group is placed in an area inside an edge of the holding member when viewed from a height direction of the vehicle. Each of the cells can be arranged to extend in the height direction of the vehicle. The holding member may be a heat dissipation plate allowing heat exchange between the cells.

This invention is polyester fibers with an initial tensile resistivity of 15 to 38 cN/dtex, a elastic recovery rate of 70% or more after 20% elongation, and a self-shrinkage percentage of 0.3% to 1.4% after dry heat treatment at 160&#xb0; C. The polyester fibers of this invention can be used to obtain a woven or knitted fabric resistant against repeated loads, excellent in surface softness and uniformity, and free from projections/recesses and curling. Since the woven or knitted fabric obtained from the polyester fibers of this invention are highly resistant against repeated loads, it can be suitably used as a car seat loaded with human bodies.
