Embodiments of the present disclosure relate to youth electric recreational vehicles. In an exemplary embodiment, a youth recreational vehicle, comprises: one or more front ground engaging members, one or more rear ground engaging members, and a frame supported by the one or more front ground engaging members and the one or more rear ground engaging members. In addition, the youth recreational vehicle comprises a seat supported by the frame and configured to support at least one rider and an electric powertrain. The electric powertrain is configured to drive at least one of: (i) the one or more front ground engaging members and (ii) the one or more rear ground engaging members. The electric powertrain comprises: a controller, at least one electric motor, and at least one battery pack.

A battery pack to be mounted on a vehicle includes a battery, a passage unit, a gas pump, a first valve, and an arithmetic and control unit. The passage unit is disposed on at least one of sides of the battery. The passage unit allows fluid to flow through an inside of the passage unit. The gas pump operates with electric power of the battery. The gas pump draws gas in the inside of the passage unit. The first valve shuts off a fluid passage through which the gas is to be supplied to the inside of the passage unit. The arithmetic and control unit controls the gas pump and the first valve, and performs a first temperature regulating process. The process includes driving the gas pump while the first valve is not shut off, and then drawing the gas from the inside of the passage unit.

An electric vehicle includes: a power storage device; a floor member disposed on a bottom portion of a vehicle body; and a cover member fixed to the floor member and forming a storage space for the power storage device between the floor member and the cover member. The electric vehicle includes: an intake port introducing air in a passenger compartment into the storage space; and an exhaust port exhausting air having been heat-exchanged with the power storage device in the storage space into the passenger compartment. The exhaust port is composed of the floor member and the cover member.

A side-by-side all-terrain vehicle, comprising: a vehicle body comprising a cockpit and a power compartment, the power compartment being located behind the cockpit; a powertrain comprising a power motor, the power motor being provided in the power compartment; and a power battery being provided in the cockpit, and the power battery being configured to supply power to the power motor. Thus, by using the power motor as a power source, exhaust gas emissions can be reduced, and the economic efficiency of an all-terrain vehicle can be improved. By providing the power battery in the cockpit, the interior space of the cockpit can be rationally used, so that insufficient rear space of the vehicle body is avoided, and the power battery suffers less external interference and has better usage safety.

A battery attachment/detachment structure for a saddle-ride type electric vehicle includes substantially rectangular parallelepiped batteries for supplying electric power to an electric motorcycle, a battery case in which the batteries are housed, a battery-side terminal provided on the bottom surface of each battery, and a case-side terminal engaged with the battery-side terminal. An operation lever for connecting or separating the battery-side terminal and the case-side terminal to/from each other by being operated in the up-and-down direction of a vehicle body, and a locking member for holding the operation lever at a position where the battery-side terminal and the case-side terminal are connected to each other are provided. The locking member regulates the movement of the operation lever towards the upper side of the vehicle body by engaging with the operation lever. The disclosed structure can regulate the movement of housed batteries to maintain excellent electrical connection with a simple configuration.

An electric snowmobile that performs heat exchange with a simple structure is provided. The electric snowmobile includes a body frame, a driver's seat, an electric motor, a ski, a track mechanism, a battery, a cooling unit that cools fluid at least in accordance with outside air, a first heat exchange unit that performs heat exchange between the battery and the fluid, a second heat exchange unit that performs heat exchange between the electric motor and the fluid, a first flow path for delivering the fluid cooled in the cooling unit to the first heat exchange unit, a second flow path for delivering the fluid cooled in the cooling unit to the second heat exchange unit, and a third flow path for delivering the fluid heat-exchanged in the first heat exchange unit and the fluid heat-exchanged in the second heat exchange unit to the cooling unit.

A three-wheeler including two front wheels and a rear wheel, left and right seats, a steering mechanism steering the front wheels, an electric motor generating a torque by electrical energy, a power transmission mechanism transmitting the torque to the front wheels, and a body frame. A center of gravity of the three-wheeler is more frontward than a front end of the two seats and than a middle point of the wheelbase, and is more rearward than a front end of the electric energy storage device. The seats is, in a top view, partially in a triangle area that has a center of each of the front wheels and the rear wheel as vertices. The electric energy storage device, in the top view, overlaps a foot-resting area and is partially in the triangle area. The electric energy storage device is between the two front wheels.

A high voltage battery unit for a vehicle and an underbody of the vehicle are provided. The high voltage battery unit mounted to the vehicle is installed under a center floor of the vehicle at the outdoor side. A drive shaft forming a drive device of the vehicle is installed to penetrate between battery built-in parts positioned at both sides with respect to a center tunnel to deliver the power of a powertrain mounted at the front of the vehicle to a rear wheel through the drive shaft.

An assembly for a hybrid motor vehicle, in particular a partially electrified hybrid motor vehicle, includes a vehicle battery and a vehicle seat having a seat surface. The vehicle seat is connected or capable of connection to a vehicle floor of the hybrid motor vehicle by means of a seat bottom construction of the seat surface. In addition, the vehicle battery is furthermore arranged or capable of arrangement underneath the vehicle seat and above the vehicle floor and a first stiffened cross member, arranged in front of the vehicle battery in the direction of travel, and a second stiffened cross member, arranged behind the vehicle battery in the direction of travel, are provided. The vehicle battery is moreover connected to the first cross member by means of a first fixing arrangement and/or to the second cross member by means of a second fixing arrangement.

A vehicle chassis including a vehicle frame defining an inner space and being operable to switch between a first expanded state and a collapsed state, and a loading device mounted to the inner space and removably connected to the vehicle frame. The loading device defines a first loading surface when the vehicle frame is in the first expanded state, and the loading device defines a second loading surface that is smaller than the first loading surface when the vehicle frame is in the collapsed state.
