Abstract: A vehicle battery pack includes a first battery module and a second battery module, a fan which includes a blade body configured to rotate about a rotary shaft, the fan being configured to supply air to the first battery module and the second battery module, and a housing configured to accommodate the first battery module, the second battery module, and the fan. The first battery module and the second battery module are arranged side by side in a second direction orthogonal to the first direction. In the first battery module, the plurality of cells are bound in the first direction by a binding member. The binding member is a plate-like member which is made of metal. The fan is arranged in such a manner that the rotary shaft faces the binding member.

Abstract: A battery unit equipped in a vehicle includes a battery, a case accommodating the battery, an upper surface covering material covering an upper surface of the battery in the case, an intake portion provided on the upper surface covering material and configured to take in air from an outside of the case to above the battery, a lower surface covering material covering a lower surface of the battery in the case, an exhaust portion provided on the lower surface covering material and configured to discharge air that has cooled or heated the battery, a fan disposed below the lower surface covering material, configured to take in air discharged from the exhaust portion, and discharge the air between the lower surface covering material and a bottom surface of the case.

Abstract: A power supply device includes: a housing; a plurality of batteries stored in the housing; a plate member arranged between the plurality of batteries; an air inlet pipe arranged above the batteries and provided with an air inlet for introducing air from the outside of the housing to guide the air toward the batteries; a fastening portion configured to fasten the air inlet pipe on the plate member; and a recess structure provided around the fastening portion of the air inlet pipe and recessed toward the batteries, wherein the recess structure has a bottom portion and a sidewall portion, the bottom portion has a surface with an acute angle in a direction away from the air inlet, and the sidewall portion is connected to the bottom portion.

Abstract: A power supply device includes: a battery; an electric device; a case accommodating the battery and the electric device; and a cover covering a case opening. The cover is provided with a first exhaust port and a second exhaust port. A first exhaust member having a first exhaust passage through which air discharged from the first exhaust port flows is connected to the first exhaust port. A second exhaust member having a second exhaust passage through which air discharged from the second exhaust port flows is connected to the second exhaust port. The first exhaust port is provided so as to overlap at least a part of the electric device when viewed from an opening direction and has a larger opening area than the second exhaust port. A minimum cross-sectional area of the first exhaust passage is smaller than a minimum cross-sectional area of the second exhaust passage.
