Abstract: A vehicle battery pack includes a battery module, a battery case configured to accommodate the battery module, and a battery cooling mechanism configured to cool the battery module. The battery cooling mechanism includes an introduction duct configured to introduce air into the battery case, an air guide member configured to guide the air, an air guide fan configured to blow the air, and a discharge duct configured to discharge the air to the outside. The air guide fan includes a fan motor, a fan case including a suction port and an air blow-out port, and an impeller. The air guide member is provided so that one end thereof is connected to the introduction duct and another end thereof seals a front surface of the battery module. The air guide fan faces the battery module in a front-rear direction, and is disposed so that the suction port faces rearward.

Abstract: A battery pack includes a battery module in which a plurality of battery cells are stacked, a battery case accommodating the battery module, and a battery cooling mechanism configured to cool the battery module. The battery cooling mechanism includes an air guide duct disposed in a first direction orthogonal to a stacking direction of the plurality of battery cells with respect to the battery module, and a cooling fan disposed on a side opposite to the air guide duct with the battery module interposed therebetween in the first direction. An air intake port of the cooling fan is open on a side opposite to the battery module in the first direction.

Abstract: An electric vehicle includes a seat which is supported on a floor panel via a support member, a battery pack which is disposed behind the seat, and an air intake duct which has an air inlet and through which air taken in from the air inlet is supplied to the battery pack. The air inlet is disposed at a position overlapping the support member as viewed from above, and is located between the floor panel and the support member in an up-down direction.
