The present disclosure relates to a cooling system and method of a HEV for cooling an engine clutch and a motor in a HEV, and includes an EOP for pumping oil from an oil pan, a flow regulating valve for adjusting a coolant amount supplied to an engine clutch and a motor in the EOP, and a controller that determines whether to adjust a coolant amount based on a temperature of the engine clutch and a temperature of the motor, accelerates a motor of the EOP based on at least one of an ATF temperature, an engine clutch temperature, a motor temperature, or a TMM control mode, and controls the flow regulating valve depending on a motor speed of the EOP to adjust the coolant amount supplied to from the EOP the engine clutch and the motor.

A work vehicle includes a hybrid transmission to vary power from an engine and output the power to a travel device, the hybrid transmission including an electric transmission including a motor generator and a gear transmission including a gear driver. The work vehicle includes an inverter to drive the motor generator. The work vehicle includes a pump to cool the inverter by supplying, to the inverter, a refrigerant to cool the motor generator.

Systems and method for charging the battery of an electric vehicle (EV) and climatically controlling the inside cabin of the electric vehicle are described. The methods include detecting that an EV is electrically connected to a charging station and then determining the current temperature inside the EV. Climatic user preferences can be retrieved and used to determine a desired climate inside the cabin when the user returns to the vehicle. Using the desired climate inside the cabin to determine an estimated charge, where the estimated charge is sufficient to both obtain the desired climate inside the cabin by the time the users return and have the battery of the vehicle charged to an acceptable level.

A forklift includes a downstream exhaust pipe that releases engine exhaust gas into the atmosphere. The downstream exhaust pipe includes a tail pipe extending in a width direction of a vehicle body. A closure part that closes a tail pipe's opening is provided at the tail pipe's tip end portion. A first exhaust port which discharges the exhaust gas rearward from the vehicle body and a second exhaust port which discharges the exhaust gas rearward from the vehicle body at the tail pipe's tip end side with respect to the first exhaust port are provided in the tail pipe's circumferential surface portion. The first exhaust port and the second exhaust port are disposed in a region where cooling air flows. A throttling part that changes a flow path area for the exhaust gas is disposed between the first exhaust port and the second exhaust port in the tail pipe.

A drive control apparatus is provided for controlling a drive system mounted in a vehicle, where the drive system includes a power generator, at least one rechargeable battery, accessories powered by electrical power supplied from either or both of the least one rechargeable battery and the power generator. In the drive control apparatus, a selector is configured to, during power generation by the power generator, select the power generator as a power source for the accessories in preference to the least one rechargeable battery. A power controller is configured to, if generated power by the power generator exceeds power consumption of the accessories, increase the power consumption of the accessories.

A plug-in vehicle capable of wired-charging a battery through a charging connector using an external charger and a method for controlling the same are provided. The method for controlling charging of a vehicle configured to perform a charging operation using external power includes determining whether a refrigerant circulation device operates normally and the amount of refrigerant is normal when a temperature sensor of a charger malfunctions. When the refrigerant circulation device operates normally and the amount of refrigerant is normal, a temperature of the charger is estimated using a temperature of a heat dissipation device through which the refrigerant passes and the output of the charger is adjusted based on the estimated temperature.

A cooling apparatus for a hybrid vehicle is provided with an oil circulating circuit supplying oil discharged from an electric oil pump to a first motor, a second motor, an inverter, and a lubrication-required part, and the oil circulating circuit includes: a first circuit supplying the oil that is discharged from the electric oil pump, and is cooled by an HV radiator to the inverter, the first motor, and the second motor; and a second circuit supplying the oil that is discharged from the electric oil pump without being cooled by the HV radiator to the lubrication-required part.
