An integrated thermal management system for fuel cell mobility vehicles, may include a hydrogen tank configured to store hydrogen supplied to a fuel cell stack, a first turbine rotated by the pressure of the hydrogen discharged from the hydrogen tank, a refrigerant circulation line configured such that a refrigerant circulates therealong and a compressor, a condenser, an expansion valve and an evaporator are provided thereon, a second turbine mounted in the refrigerant circulation line and rotated by the high-pressure refrigerant discharged by the compressor, and a blower configured to pressurize ambient air using the rotation force of the first turbine, the second turbine or an electric motor and to supply the pressurized ambient air to an indoor air conditioning unit or the fuel cell stack.

An electric water pump may include: a housing with a cooling water inlet and a cooling water outlet; and a stator assembly provided inside the housing. The stator assembly includes a stator core, a stator coil arranged on the stator core, insulation members insulating the stator core and the stator coil, and a stator cover provided to cover the stator core, the stator coil, and the insulation members. The electric water pump further includes: a rotor assembly rotatably provided inside the stator assembly and having a magnetic body; and an impeller pumping cooling water introduced through the cooling water inlet by rotation of the rotor assembly. In particular, the stator core, the stator coil, and the insulation members of the stator assembly may be integrally formed in the stator cover.

A hydraulic circuit is pressurized by a hydraulic pump driven by a power source in a machine. The hydraulic circuit is configured to use pressurized fluid from an accumulator to drive a hydraulic accessory when the hydraulic pump is inactive and the power source is shut down for fuel savings during idle operations. A valve may be configured to selectively supply pressurized hydraulic fluid to the accessory when the pump is inactive.

An auxiliary power unit for a vehicle is configured to provide cool or heated air within the vehicle with the main engine off. The auxiliary power unit includes an auxiliary diesel engine that receives fuel from the fuel tank of the vehicle. The auxiliary diesel engine is connected to a hydraulic pump of a hydraulic power system by a first magnetic clutch to provide mechanical power. The hydraulic pump converts the mechanical power to hydraulic power. The hydraulic power system delivers the hydraulic power to a hydraulic compressor drive motor that converts it back to mechanical power. The hydraulic power system is connected to a compressor drive via a second magnetic clutch. The compressor drive provides power to an air conditioner (AC) compressor of the vehicle such that the AC compressor activates while the auxiliary power unit is operating.

A transport climate control system configured to provide climate control within a climate controlled space towed by a vehicle is provided. The transport climate control system includes an electrical isolation box configured to house and a drive module and a compressor. The drive module receives power from a vehicle power network including a rechargeable energy storage system (RESS) to power the compressor. The drive module and the compressor are electrically isolated at a climate control system electrical potential reference, which is different from an electrical potential reference of a vehicle chassis to which the electrical isolation box is connected.
