The present invention is a battery mounting device which comprises a battery mounted in a cabin of a vehicle, a plate-shaped toe board provided in front of a passenger seat at a position located at a lower level than the passenger seat so as to cover the battery, wherein the battery is provided between the toe board and a floor panel of the vehicle.

The disclosure provides a stack frame that is arranged in a front portion of a vehicle and on which a battery stack is mounted. The stack frame includes a body section and a crash box. The body section includes plural members that are welded to each other along a weld line. The weld line between the plural members extends in a front-back direction of the vehicle. The crash box is arranged on a front side of the body section. A lateral wall surface of the crash box is displaced from an extended line of the weld line.

A battery module includes a first cell group and a second cell group. The first cell group is provided with a plurality of cells each including a top surface on which terminal are arranged, a bottom face, a pair of long side faces, and short side faces shorter than the long side faces, the pair of long side faces being arranged to be opposed to each other. The second cell group is provided with a plurality of cells each including long side faces arranged to be opposed to each other, the cells being arranged at a position parallel with the first cell group.

Vehicles may be composed of a relatively few number of modules that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.

A method and system for swapping batteries in an electric vehicle is disclosed. The method includes dismounting a first battery assembly, moving to a second battery assembly and mounting the second battery assembly onto the vehicle. Mounting and dismounting are accomplished by an onboard mounting and dismounting system. The method can be used in a zero infrastructure environment such as an underground mine since mounting and dismounting are accomplished by components on the vehicle itself. An auxiliary battery pack powers the vehicle during between dismounting a battery pack and mounting another battery pack.

Provided is a vehicle with a fuel cell unit, specifically, a vehicle with a configuration in which a fuel cell unit is arranged anterior to a dashboard as well as a toe board located below the dashboard, where the fuel cell unit is arranged to be prevented from colliding with the toe board upon occurrence of unforeseen impact on the fuel cell unit. The fuel cell unit includes at least a fuel cell group, a stack manifold provided on the fuel cell group on the vehicle rear side, and an air valve device fixed to the stack manifold. The stack manifold has a recess portion formed in a part thereof. The air valve device is fixed to the stack manifold with at least a part of the air valve device received within the recess portion.

A fuel cell system includes a stack case storing a fuel cell stack, and an auxiliary device case containing a fuel gas system device and an oxygen-containing gas system device. The auxiliary device case covers the fuel gas system device in a manner to protect the fuel gas system device against the external load, and includes a first case member provided with a mount fixed to a vehicle body frame, and a second case member made of material having specific gravity smaller than that of the first case member, and covers at least the oxygen-containing gas system device.

A front compartment is provided with an engine, an air cleaner, a radiator, a reservoir tank, a motor unit, an auxiliary battery, and an EFI-ECU. The engine, the reservoir tank, the motor unit and the EFI-ECU are aligned in a vehicle's width direction. The air cleaner and the auxiliary battery are also aligned in the vehicle's width direction. The air cleaner is located in front of the motor unit. The motor unit includes a power control unit and a transaxle. The air cleaner is located in front of the power control unit. The auxiliary battery is located diagonally forward to left of the motor unit.

To provide a fuel cell system to be mounted in a space below the hood of a vehicle. The fuel cell system includes an FC assembly including an FC stack and a controller for controlling the FC stack; a cooling mechanism for cooling the FC stack, using a completely sealed cooling channel; and a reserve tank provided on a way of the cooling channel, the reserve tank being for storing coolant, wherein the reserve tank is disposed horizontally adjacent to the FC assembly.

A support frame includes a first member, a second member, and a third member each having a surface. The first member is connected to the second member by fitting, and the first member is connected to the third member by fitting. In each of connecting portions, one of members connected to each other is defined as a first connecting member and the other one of the members is defined as a second connecting member. A side end portion of the first connecting member on a side facing the second connecting member is provided with an extending portion. The extending portion has a flat shape, and the extending portion is provided with a fitted portion constituted by a recessed portion. A side end portion of the second connecting member on a side facing the first connecting member is provided with a fitting portion configured to fit in the fitted portion.
