Abstract: An air-conditioning system and method of climate control for a fuel cell vehicle are provided herein. The system and method include a vacuum enclosure having an adsorber and an evaporator/condenser assembly. A conduit and valve system operates the air-conditioning system in two modes of operation to provide uninterrupted cooling to a passenger cabin, among other things. In one mode of operation, the adsorber is regenerated using waste heat from a fuel cell stack.

Abstract: Methods and system for operating a thermal storage device of a vehicle system are provided. In one example, a method comprises estimating a temperature of a thermal battery after the battery and coolant included therein have reached thermal equilibrium, and determining a state of charge of the battery based on the estimated temperature and one or more chemical properties of two phase change materials included within the battery. Specifically, the thermal battery may include two phase change materials with different melting points for providing thermal energy to warm coolant in a vehicle coolant system.

Abstract: Fuel-cell thermal management systems and control schemes therefore are disclosed. In one embodiment, the system may include a fuel-cell stack, a heat-exchanger, a thermal battery including a material having a melting temperature of 50-120° C., a first coolant loop including the fuel-cell stack and the thermal battery and excluding the heat-exchanger, and a second coolant loop including the fuel-cell stack, the thermal battery, and the heat-exchanger. The first and second coolant loops may be configured to heat and cool the fuel-cell stack, respectively. The system may include a controller or processor configured to direct coolant to transfer heat from the thermal battery to the fuel-cell stack based on a negative heat rejection status of the fuel-cell stack and to transfer heat from the fuel-cell stack to the thermal battery based on a positive heat rejection status of the fuel-cell stack when the thermal battery is below a target temperature.

Abstract: A system for regulating lubricant temperature within a vehicle axle is provided. A differential housing has a primary chamber that contains the differential, and a secondary chamber separated from the primary chamber. A sump is in the primary chamber for collecting lubricant. An inlet to the secondary chamber allows the lubricant to flow from the primary chamber into the secondary chamber. An outlet to the secondary chamber allows the lubricant stored therein to be purged into the sump. When the lubricant is below a certain threshold temperature, a temperature-responsive valve is configured to close to inhibit the fluid to travel through the outlet. When the temperature of the lubricant rises to exceed the threshold, the valve is configured to open and permit the fluid to travel through the outlet.

Abstract: A thermal management system for an electrified vehicle and a method for managing such a system, includes a coolant subsystem to cool a battery pack and a refrigerant subsystem. The coolant subsystem includes a battery chiller in fluid communication with a cooling system inlet to the battery pack. The refrigerant subsystem includes a chiller cooling subsystem to cool the battery chiller and a cabin cooling subsystem to cool a passenger cabin, wherein the chiller cooling subsystem and the cabin cooling subsystem are completely separate from each other.
