A fuel tank venting system for a hybrid vehicle includes a first flow path configured to deliver fuel vaporized from a fuel tank to a canister, a second flow path configured to deliver air used for cooling a high voltage battery to the canister, a first three-way valve disposed on the second flow path and configured to control opening and closing of a first discharge port for releasing pressure of the fuel tank, a second three-way valve disposed on the second flow path and configured to control opening and closing of a second discharge port for flowing the air used for cooling the high voltage battery into the canister or discharging the air used for cooling the high voltage battery outside the vehicle, and a controller configured to control the first three-way valve and the second three-way valve.

The present invention relates to a passive safety cell (2) for passenger cars with alternative powertrains which is shared for the passengers (3) as well as for the energy source (4) with its main components, to protect both units in one cell.

A fuel cell vehicle mounted with a fuel gas tank in an underfloor of the vehicle. The fuel cell vehicle includes: a floor that has a projecting portion projecting upward in a height direction of the vehicle and extending along a front and rear direction of the vehicle; a fuel gas tank arranged under the projecting portion in the height direction of the vehicle and fixed to the floor; and an undercover arranged under the fuel gas tank in the height direction of the vehicle. The undercover has a fixation protruded portion that projects upward in the height direction of the vehicle in a side of the fuel gas tank in a width direction of the vehicle, and being fixed to the floor by the fixation protruded portion.

There is provided a fuel tank including: a fuel tank main body enclosed by a floor wall, side walls and an upper wall; and a separator including a strut, a first plate portion in which a first penetrating hole that penetrates in a plate thickness direction is formed, and a second plate portion in which a second penetrating hole that penetrates in a plate thickness direction is formed, the second plate portion sandwiching the strut with the first plate portion and extending in a diametric direction at an opposite side of the strut from a side thereof at which the first plate portion is disposed, wherein at least one of shapes, sizes or numbers of the first penetrating hole and the second penetrating hole is set to be different such that fluid resistances at the first plate portion and the second plate portion are different.

A pressure vessel mounting structure includes: a manifold including a discharge gas passage branching from a general passage via which a container body communicates with a valve; a fusible plug valve configured to close the discharge gas passage and to, when the fusible plug valve is melted, open the discharge gas passage such that the high-pressure gas is discharged; a case including a bottom face portion covering the container body and the manifold from below in the vehicle up-down direction, the case including a bead placed near the fusible plug valve, the bead being formed by protruding a part of the bottom face portion upward in the vehicle up-down direction; and a communicating opening via which a space under a floor of a vehicle communicates with the fusible plug valve, the communicating opening being formed in a part of the bead, the part facing the fusible plug valve.

A frame arrangement for a vehicle may include a first side member and a second side member that each have an upper portion and a lower portion. The upper portions are spaced laterally apart by a first distance, and the lower portions are spaced laterally apart by a second distance less than the first distance. The frame arrangement may further include a first battery positioned between the lower portions of the side members, and a second battery positioned between the upper portions of the side members.

An electric rotary machine case, which has a cylindrical shape and accommodates an electric rotary machine, includes a passage extending along a rotation axis direction of the electric rotary machine on an outer periphery of the electric rotary machine, and a protrusion portion protruding radially outward from an outer peripheral surface of the electric rotary machine case, the protrusion portion having the passage formed inside the protrusion portion. The protrusion portion has a flat surface in a cross-section orthogonal to a rotation axis of the electric rotary machine.

A drive unit includes: a rotary electric machine; a rotary electric machine case accommodating the rotary electric machine; an electric power conversion device electrically connected to the rotary electric machine and configured to convert electric power supplied to the rotary electric machine and electric power supplied from the rotary electric machine; and an output shaft extending out from the rotary electric machine case and configured to output power of the rotary electric machine. The electric power conversion device is arranged on one side of the rotary electric machine. The output shaft is arranged between the rotary electric machine and the electric power conversion device.

The present invention relates to a passive safety cell (2) for passenger cars with alternative powertrains which is shared for the passengers (3) as well as for the energy source (4) with its main components, to protect both units in one cell.

A vehicle body structure includes a battery mounting portion arranged on a floor of a vehicle and having a battery disposed thereon; a first cross member arranged in a front side of the battery mounting portion and reinforcing the floor; a second cross member arranged in a rear side of the battery mounting portion and reinforcing the floor; first and second extension members extending in a longitudinal direction so as to connect the first and second cross members while being spaced apart from each other in a transverse direction, and reinforcing a lower portion of the battery mounting portion; and a coupling structure coupled to the first and second cross members in a state of coupling the battery.
