To provide a vehicle drive device capable of efficiently driving a vehicle by using a motor without falling into the vicious cycle between enhancement of driving via the motor and an increase in vehicle weight. The present invention is a vehicle drive device (10) having a motor for driving the wheels of a vehicle and includes a front wheel motor (20) for driving front wheels (2b) of a vehicle (1) and a battery (18) and a capacitor (22) that supply electric power for driving the front wheel motor (20), in which the voltage of the battery (18) and the capacitor (22) connected in series is applied to the front wheel motor (20) and the capacitor (22) is disposed between the left and right front wheels (2b) of the vehicle (1).

The disclosure provides an electric vehicle. The electric vehicle includes: a vehicle body provided with a power input port and a power supply device. The power supply device includes a charger and a detachable battery pack. The charger includes a power interface for obtaining external power, a charging portion provided with a docking interface, an output part, and a control unit. The output part includes a first power output interface connected with the power input port to supply power to the electric vehicle. When the power interface is connected with the external power, the control unit controls the charging portion to charge the battery pack.

A hybrid driving apparatus includes an internal combustion engine, a motive power transmission mechanism transmitting a driving force to main driving wheels, a main driving electric motor generating a driving force of the main driving wheels, an accumulator, sub-driving electric motors generating driving forces of sub-driving wheels, and a control apparatus executing an electric motor traveling mode and an internal combustion engine traveling mode. The sub-driving electric motor is provided to each of the sub-driving wheels, the control apparatus causes only the main driving electric motor to generate the driving force in the electric motor traveling mode and causes the main driving electric motor and the sub-driving electric motors to generate the driving forces in acceleration of the vehicle at a predetermined vehicle speed or higher, and although the engine generates the driving force, it does not cause the motors to generate driving forces in the traveling mode.

A vehicle body includes a floor member, a support member coupled to an upper surface of the floor member, and a frame member coupled to an upper end of the support member to define a space between the floor member and the frame member, wherein the space is configured to house an item. The item may include a high-voltage battery.

A body floor (1) for an electric vehicle (2) has a battery frame (3) that receives battery modules (4). An interior cover (5) separates an interior (6) from the battery modules (4). At least one crossmember (7, 8) extends transverse to a vehicle longitudinal direction (9) and is on the battery side of the interior cover (5). A seat attachment (10) for connecting a vehicle seat (11) is arranged on the interior side of the interior cover (5). The battery modules (4) are attached to the crossmember (7, 8) by the battery frame (3), and the body floor (1) is a supporting component of the body structure of a vehicle (2). The seat attachment (10) is attached to the body floor (1) on the battery side of the interior cover (5). With this construction, the vehicle seat is low while simultaneously arranging battery modules below the vehicle seat.

The invention relates to a device for installing traction batteries underneath a cab of a cab-over-engine vehicle. A base portion defines a space into which a portion of a traction battery pack is receivable by lowering the traction battery pack into said space. Front and rear securing element are connected to the base portion for securing the base portion to front and rear bushings, respectively, of the vehicle. At least one of the securing elements comprises a first securing portion for connecting that securing element to one of said bushings, respectively, and a second securing portion projecting upwardly from the base portion for connecting that securing element to the traction battery pack when the traction battery pack has been received in said space.

A work machine includes a battery pack, a first vent provided at a rear end of a machine body, a fan located between the first vent and the battery pack, a second vent located in front of and above the battery pack, and an electric motor rotated by electric power from the battery pack.

An energy storage device for a motor vehicle includes a plurality of round cells for electrochemically storing energy, and a storage housing in which the plurality of round cells is provided. In the installed position, the round cells run substantially parallel to the vehicle transverse axis. The round cells are arranged within the storage housing in multiple layers in the direction of the vehicle vertical axis, wherein the number of layers varies in the direction of the vehicle longitudinal axis.
