  • Patent number: 9966640
    Abstract: The efficiency in layout of an exhaust space for a power source apparatus mounted in an in-car space is increased and uncomfortableness is suppressed due to air discharged from the power source apparatus into the in-car space. A vehicle on which a power source apparatus is mounted includes the power source apparatus disposed in an in-car space of the vehicle, a cooling apparatus supplying air within the in-car space to the power source apparatus, and a cooling duct which the air discharged from the power source apparatus flows. The cooling duct is connected to any one of a first cooling flow path formed by a pillar of the vehicle, a second cooling flow path formed by a frame portion of the vehicle and a stepped portion provided for the frame portion, and a third cooling flow path formed by the frame portion and a scuff plate portion.

  • Patent number: 9577232
    Abstract: The power storage device comprises a plural cell, an exhaust passage and a sealing plate. The plural cells is aligned in a first direction, each of the cells includes a gas discharging valve for discharging a gas generated in the cell, each of the gas discharging valves is provided on a first side in a second direction of the cell, and the second direction is orthogonal to the first direction. The exhaust passage is configured to discharge the gas discharged from each of the gas discharging valves, extends in the first direction, and has an opening at a first end in the first direction. The sealing plate is provided at a second end of the exhaust passage in the first direction, includes plural recesses on a surface on the exhaust passage side of the sealing plate, and made of a resin.
