The system may allow waste heat within an ICE to be stored in a RESS, and may cool the RESS by depositing heat in the ICE. The RESS and the ICE are located in a first coolant circuit and a second coolant circuit, respectively. The system also includes a third coolant circuit interconnected with the first coolant circuit, and in thermal communication with the second coolant circuit via a first heat exchanger. The first and third coolant circuits are configured to circulate a first coolant, and the second coolant circuit is configured to circulate a second coolant. The RESS and the ICE are each configured to selectively operate as a heat source or a heat sink.08-07-2014
20140230463METHOD FOR CONTROLLING A COMPRESSOR OF A THERMAL STORAGE HEAT PUMP SYSTEM - A method of controlling a compressor of a thermal storage heat pump system of a vehicle is provided. The system may operate in one of a heating mode and a cooling mode, as determined by at least one system controller based on at least one parameter. The at least one parameter may be ambient air temperature. The compressor has a compressor motor and a motor controller configured to selectively operate the compressor in an unmodified state or a modified state based on the operating mode of the system. The compressor motor is operated in the unmodified state when the system is in the cooling mode, and in the modified state when the system is in the heating mode. Operating the compressor motor in the modified state may include decreasing its coefficient of performance (COP).08-21-2014
20140277878METHOD FOR OPERATING HYBRID VEHICLE - A method and system used to identify an optimal hybrid vehicle operating mode based on a variety of potential factors, and then recommend the optimal operating mode to the driver so that they can make an informed decision regarding their operating mode selection. In one embodiment, the method uses geographic-, vehicle- and/or environmental-related factors to establish one or more operating zones, monitors the location of the hybrid vehicle and determines when it is within one of the operating zones, and then determines an operating mode that is optimal for that particular operating zone.09-18-2014
