Problems solved by technology

[0006] However, if the spare tire is not stored above the power supply unit, and the floor height of the luggage room and the cabin is restricted to be low to ensure a large space for the luggage room and the cabin, it is difficult to adopt the above structure, and there is room for improvement.
That is, in the cooling structure of the vehicle power supply unit described in Patent Document 1, the floor height of the luggage room and the cabin cannot be restricted to be low due to the interference of the air supply duct.

Abstract

The invention provides a cooling mechanism of a vehicle battery, which can inhibit pressure loss caused by air supply and can ensure a spacious space. An air inlet pipeline (15) comprises a first pipeline component (20), at least a part of which is disposed under a floor, an upstream side second pipeline component (21) and a downstream side second pipeline component (22), which are disposed at a position other than below the floor. A connection part (45) of the first pipeline component (20) and the downstream side second pipeline component (22) is disposed at a position other than below the floor.

Description

Technical field [0001] The present invention relates to a cooling structure suitable for batteries in vehicles such as electric vehicles and hybrid vehicles. Background technique [0002] In electric vehicles and hybrid vehicles, for example, a battery as a driving energy source for an electric motor is mounted under the floor of a luggage space. A battery is a heat-generating component that generates heat during charging and discharging, and therefore needs to be cooled to maintain battery performance. A solution for cooling using cooling air introduced from the interior of the vehicle or the like has been studied (for example, refer to Patent Document 1). [0003] The cooling structure of the power supply unit for a vehicle described in Patent Document 1 uses a cooling fan to introduce air in the vehicle cabin from an air inlet provided near the rear seat, and supplies the air as cooling air to the power supply unit containing the battery Cool down. Use the tire tray for the sp...
