A vehicle adapted to improve cooling capacity and a carrying capacity of two types of batteries and implementing miniaturization of a system including the batteries, a battery unit and a battery carrying method of the vehicle are provided. The vehicle (1) includes a first power storage element (11), a second power storage element (12) with output weight density superior to that of the first power storage element (11), a motor (9) driven by at least one of electric powers of the first and second power storage elements (11) and (12), where the first and second power storage elements (11) and (12) are disposed outside a passenger compartment (5) and disposed under the passenger compartment (5) along a vertical direction, and the second power storage element (12) is disposed at a front end along a front and rear direction of the vehicle compared to the first power storage element (11).

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.

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.

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.

A work vehicle includes a propelling device, which consists of a pair of right and left front wheels and a pair of right and left rear wheels, an engine configured to drive one of the pair of front wheels and the pair of rear wheels, an electric motor configured to drive the other of the pair of front wheels and the pair of rear wheels, a battery configured to supply electric power to the electric motor, and a controller configured to control the electric motor. The controller performs regeneration control at constant current value to charge the battery with regenerative power of the electric motor at a constant current value regardless of rotation speed of the electric motor.

A power unit of an electric vehicle may be connected to a main battery, an AC inlet, and a DC inlet. The power unit may include a battery connector to which a battery power cable is connected, an AC inlet connector to which an AC inlet power cable is connected, and a DC inlet connector to which a DC inlet power cable is connected. The battery connector may be closer to the main battery than a center of the power unit is to the main battery. The AC inlet connector may be closer to the AC inlet than the center of the power unit is to the AC inlet. The DC inlet connector may be closer to the DC inlet than the center of the power unit is to the DC inlet.

An axle drive apparatus of the present invention includes an adapter unit that has an adapter case connectable to an axle drive case while supporting a first motor, an adapter input member connected to an output shaft of the first motor by connection of the first motor to the adapter case, an adapter output member that is connected to an axle drive input member of the axle drive apparatus by connection of the adapter case to an axle drive case, and an adapter power transmission mechanism that operatively transmits the rotational power of the adapter input member to the adapter output member.
