A thermal management system includes a switching valve that switches between a first mode in which first and second flow paths are separated and a second mode in which parts of the first and second flow paths are connected. In the first mode, a control unit acquires measured values of first and second temperatures in the first and second flow paths and estimated values of the first and second temperatures when the switching valve is not in a slightly open state. The switching valve is in the slightly open state when the measured value of the first temperature is higher than the estimated value of the first temperature by a value greater than a first predetermined threshold and the measured value of the second temperature is lower than the estimated value of the second temperature by a value greater than a second predetermined threshold.

A power and cooling assembly is disclosed for use with a vehicle having a deck for a rotatable tool such as a mowing blade. An electric motor is mounted on the deck and used to drive the blades by an output shaft. A circulating pump is connected to a housing of the electric motor and is also driven by the electric motor. The circulating pump is hydraulically connected to at least one sump on the vehicle and at least one electrical component of the vehicle to provide cooling thereto. Additional cooling pumps may be provided on the vehicle and may provide cooling to additional electrical components.

A cooling device for a vehicle, includes a cooling circuit including a first circuit in which a cooling liquid circulates through a power control unit and a second circuit connected in parallel with the first circuit and in which the cooling liquid circulates through a battery without passing through the power control unit; and a flow-rate control unit that controls a proportion of a flow rate of the cooling liquid between the first circuit and the second circuit, and when the battery is being charged with the electric power of the external power supply, the control unit controls so that the flow rate of the cooling liquid flowing through the second circuit is greater than the flow rate of the cooling liquid flowing through the first circuit on a side of the power control unit.

An electric work vehicle includes a battery, a motor positioned under the battery and drivable on electric power supplied by the battery, a travel device drivable by the motor, an inverter positioned under the battery and forward of the motor to convert direct-current electric power from the battery into alternating-current electric power and supply the alternating-current electric power to the motor, and a transmission positioned backward of the battery to transmit a driving force of the motor to the travel device, wherein the motor and the inverter are arranged in a front-back direction of a machine body.

An electric work vehicle includes a travel battery, an auxiliary battery, a motor drivable on electric power supplied by the travel battery, a travel device drivable by the motor, a voltage converter positioned forward of the travel battery to step down a voltage of electric power from the travel battery and supply the electric power to the auxiliary battery, and a radiator positioned forward of the travel battery, wherein the voltage converter and the radiator are laterally next to each other in a plan view.

Disclosed herein is an electric power and thermal management system in which, when a shaft is rotated due to an operation of a power part, generation of electric power and a circulation of a fluid are performed together so that the generation of the electric power and a circulation structure of oil are integrated, and thus a layout can be reduced, and a structure can be simplified. In addition, in a state in which the generation of the electric power and the circulation structure of the oil are integrated, a circulation amount of the oil is adjusted according to an angle of an inclined plate constituting a pumping mechanism so that an oversupply of the oil to parts through which the oil is circulated can be prevented.

A cooling system for a vehicle is provided. The cooling system includes a condenser having a first inlet header, a first outlet header, and a plurality of first tubes connecting between the first inlet header and the first outlet header. Additionally, a radiator of the system includes a second inlet header, a second outlet header, and a plurality of second tubes connecting between the second inlet header and the second outlet header. A fan assembly is disposed in front of or behind the condenser and the radiator and includes at least one cooling fan. The condenser and the radiator are arranged side by side on the front of the vehicle.

An integration component for a temperature-control system of a motor vehicle, by which component a fluidic circuit is formed, has a finished part for conducting a coolant and at least one fluid element. The finished part has an outer housing; a cooling channel structure which is formed by a network of cavities within the outer housing and is intended for conducting the coolant; cooling channel connections for cooling channels of the cooling channel structure, which connections are formed in one piece with the outer housing and can be coupled to components of the temperature-control system; and at least one receiving portion for the at least one fluid element, wherein the at least one fluid element is located above the receiving portion in order to influence a flow of the coolant in at least one cooling channel of the cooling channel structure.

Vehicle platforms and thermal management systems, subsystems, and components for use therewith are described. Thermal management architectures and systems incorporate thermal management cycles for one or more of drive train, energy storage and passenger cabin systems. Thermal manage architectures are provided such that the flow of heating and cooling fluids through such thermal management cycles may be combined in various configurations. Systems having thermal management cycles for drive train (e.g., motor, transmission, etc.) and energy storage (e.g., battery) that may be operated through a combined heating/cooling fluid loop are also provided. Embodiments are also directed to systems having thermal management cycles for the HVAC that is fluidly isolated, but thermally coupled to one or both of the drivetrain and energy storage components. Heating/cooling loops for these thermal management cycles may be functionally linked through one or more valves such that the fluid flow through such cycles may be combined together, isolated from each other or mixed in various desired configurations.

This disclosure is directed to supercapacitor systems for supporting relatively high power transient electrical loads within vehicles. An exemplary supercapacitor system includes a mounting assembly and a supercapacitor housed within the mounting assembly. The mounting assembly may be employed to mount the supercapacitor system within a vehicle, such as within a cowl assembly or cargo space of the vehicle. The mounting assembly may include multiple panels. At least one of the multiple panels may be made of a thermally conductive polymer, and at least one other panel of the multiple panels may be made of a polymer that is reinforced by a structural foam.
