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 vehicle power source system includes: a high-voltage battery; a high-voltage system equipment having a DC-DC converter and a charger; and a cooling circuit having a high-voltage battery cooling unit for cooling the high-voltage battery, a DC-DC converter cooling unit for cooling the DC-DC converter, and charger cooling unit for cooling the charger. In the cooling circuit, the DC-DC converter cooling unit and the charger cooling unit are disposed in parallel on a downstream side of the high-voltage battery cooling unit.

A forklift includes an integrated battery box. The forklift includes a forklift body having a mounting chamber with an opening to a side of the forklift body. The battery box is loaded into the mounting chamber from the side opening. After the battery box is loaded into the mounting chamber, a mechanical connection between the battery box and the forklift is realized by the locking mechanism, and a circuit connection between the battery box and an electric control mechanism of the forklift is realized by a plug-in device.

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 chassis for a mobility aid, the mobility aid including at least one base two lateral walls, and at least one connecting element which connects the two lateral walls. The chassis includes a plurality of positioning aids for each lateral wall, a bracket that can be connected to one lateral wall in at least three different configurations, and a drive unit that is connected to each bracket, wherein a bracket configuration on the lateral walls determines the type of drive for the mobility aid.

A battery electric counterbalanced forklift reliably prevents rainwater from entering an electrical part compartment in a counterweight and also allows a battery cover attachment task to be performed more readily than conventionally. The forklift includes a body frame forming a battery compartment within a vehicle body, an openable battery cover closing the battery compartment, a counterweight disposed adjacently behind the body frame, a hinge rotatably joining the body frame and the battery cover, and an inner cover disposed so as to extend widthwise beyond a boundary between the body frame and the counterweight. The inner cover and the hinge are fastened together to the body frame at a portion forming the boundary.

A power equipment unit includes: a power equipment which supplies electric power to a motor; a controller which controls the power equipment; and a harness which connects the power equipment and the controller. The power equipment and the controller are disposed so as to be adjacent to each other in a forward/backward direction with a space interposed therebetween, and the harness includes: a first harness part extending through the space in a vertical direction; and a controller connecting part connected to the controller from below.

A vehicle high-voltage system equipment unit includes a high-voltage system equipment, and a cooling fan for taking in air from a passenger compartment. The high-voltage system equipment is cooled with air taken in from the passenger compartment, the cooling fan is provided on an upstream side of the high-voltage system equipment, and an air discharge portion is provided on a downstream side of the high-voltage system equipment, a branch portion for dividing a flow of air used to cool the high-voltage system equipment is provided in the air discharge portion, an air flow regulating portion is provided on an upstream side of the branch portion, and the air flow regulating portion is formed integrally with the high-voltage system equipment.

A vehicle includes an integrated floor and traction battery support assembly. The assembly includes a floor panel and cross-members each having an upper portion attached to a lower surface of the floor panel and extending laterally across the floor panel. The assembly further includes a battery tray attached to lower portions of the cross-members and cooperating with the lower surface to define a battery-pack enclosure. A battery pack is disposed in the enclosure.
