Abstract: A cooling mechanism of a battery pack includes a first refrigerant flow path provided on an opposite side of a partition wall from a first battery module, a second refrigerant flow path provided on the opposite side of the partition wall from a second battery module, and a connection flow path connecting respective one ends of the first refrigerant flow path in a forward-rearward direction to each other and the second refrigerant flow path to each other and extending in a leftward-rightward direction. The partition wall includes a plurality of pyramid-shaped convex portions arranged in a staggered manner along the forward-rearward direction and the leftward-rightward direction inside the first refrigerant flow path and the second refrigerant flow path, two diagonal lines of the convex portion are respectively arranged to coincide with the forward-rearward direction and the leftward-rightward direction.

Abstract: A battery pack is provided with: a battery module having a cell stack configured by stacking a plurality of cells; and a cooling mechanism for cooling the battery module. The cooling mechanism is a refrigerant flow passage through which a liquid medium passes. The cell stack and the refrigerant flow passage are arranged with a bottom plate interposed therebetween. A plurality of protrusions are provided on the lower surface of the bottom plate. The plurality of protrusions are arranged in a staggered pattern along the stacking direction of the cells.

Abstract: A vehicle includes a motor, a high-voltage device, and a power converter. The motor moves the vehicle. The high-voltage device is disposed inside a vehicle cabin of the vehicle. The power converter is disposed outside the vehicle cabin. The power converter is connected to the motor and the high-voltage device to convert electric power output from the high-voltage device and to supply the converted electric power to the motor. The high-voltage device is arranged to be juxtaposed to the power converter along a front-rear direction of the vehicle.

Abstract: A vehicle includes a battery module and an exhaust duct to discharge air from the battery module. A first side member is provided along a first side trim to provide a space between the first side member and the first side trim in a vehicle width direction. The space is connected to the battery module via the exhaust duct. A rear seat is provided in a vehicle interior. A first exhaust port is connected to the exhaust duct via the space and provided in the vehicle interior below the rear seat in a vehicle height direction. A second exhaust port is connected to the exhaust duct via the space and provided in the vehicle interior behind the rear seat in a front-rear direction. The air is discharged from the exhaust duct through the first exhaust port and the second exhaust port via the space.

Abstract: A vehicle includes a floor panel, a battery module, a heater duct, and an exhaust duct. The battery module is disposed on the floor panel under a seat. The heater duct is disposed on the floor panel to discharge air output from an air conditioner through the heater duct. The exhaust duct is provided on the floor panel to discharge air output from the battery module through the exhaust duct. The exhaust duct intersects the heater duct viewed in a height direction of the vehicle.

Abstract: A battery unit includes a battery module, an upper frame member, a battery case, a battery cover, a sealing member, and a sealing bolt. The battery module is suspended from the upper frame member. The battery case has an opening to accommodate the battery module in the battery case. The battery cover is to cover the opening of the battery case. The sealing member is to seal a gap between the battery case and the battery cover. The sealing bolt is provided on the battery cover and secured to the upper frame member to connect the battery module and the battery cover via the upper frame member.

Abstract: A vehicle includes a floor panel, a battery module, an exhaust duct, and a carpet. The battery module is disposed inside a vehicle interior. The exhaust duct is provided on the floor panel to discharge air output from the battery module through the exhaust duct. The carpet is disposed on the floor panel so as to cover the exhaust duct. The carpet has ventilation holes such that air discharged from the exhaust duct is to pass through a space between the floor panel and the carpet and to be discharged into the vehicle interior through ventilation holes.
