Abstract: A hub assembly for construction of a fan includes a hub plate having a front face, a rear face, and an annular surface extending between the front face and the rear face. The hub plate defines a hub assembly axis extending through the front face and the rear face which is configured to coincide with the fan axis. The hub assembly further includes a plurality of elongated root sections that are circumferentially spaced apart and extend radially from the annular surface. The elongated root sections have a substantially circular cross-section. The hub plate and the plurality of elongated spokes are unitarily formed.

Abstract: An energy storage device cooling system includes a housing, at least one energy storage device within the housing, and a coolant circuit including a first flow portion extending through the housing, the coolant circuit configured to supply coolant for heat exchange with the at least one energy storage device. The energy storage device cooling system also includes a chiller system including: a coolant supply, a heat exchanger, and an outlet in fluid communication with the first flow portion. The energy storage device cooling system also includes a controller configured to alter a function of the chiller system when a sensed temperature does not exceed a first temperature threshold.

Abstract: In one aspect, a pump-motor assembly is provided outside of and adjacent to a storage container that stores a back-up energy storage unit. The pump-motor assembly includes a pump-motor that maintains a minimum pressure of a liquid coolant in a liquid coolant system that cools the back-up energy storage unit, and a housing that is completely enclosed, the housing containing the pump-motor, and having a removable access panel on one side thereof the enclosed structure, and an opening on another side thereof to the storage container.

Abstract: In one aspect, a thermal management system includes a first coolant circuit, through which a first coolant circulates, and including at least a radiator for cooling the first coolant, a storage containing one or more power electronics, a heat exchanger, and a thermostatic valve that outputs the first coolant to at least one of the storage containing the one or more power electronics and the heat exchanger. A second coolant circuit, through which a second coolant circulates, includes the heat exchanger configured to cool the second coolant using the first coolant, an energy storage unit cooled by the second coolant, and a refrigeration unit configured to cool the second coolant. A coolant temperature sensor outputs a temperature of the coolant in the second coolant circuit, and a controller controls at least the refrigeration unit based on the temperature of the coolant output by the coolant temperature sensor.
