Abstract: A climate-control system for a vehicle, comprising a controller in communication with a chiller configured to cool a vehicle battery and an evaporator configured to cool a vehicle cabin. The controller is configured to output a target chiller-pump speed based upon a difference between a battery coolant temperature and a target-battery coolant temperature to mitigate a temperature swing of air entering the cabin, and limiting the target chiller-pump speed in response to an available capacity of the chiller.

Abstract: A battery thermal management system includes a passenger cabin air-conditioning refrigerant loop including at least one evaporator in fluid communication with a chiller and a battery pack coolant loop in fluid communication with the chiller.

Evaporator temperature is determined by providing at least one evaporator temperature sensor.

The cooling system has a chiller, a radiator, and conduit and valving arranged to form a thermal circuit configured to selectively transport heat via coolant from the traction battery to the radiator. The vehicle also includes a grille shutter assembly having an opening and shutters movable to alter an effective cross-sectional area of the opening. A controller is programed to operate the shutters to change the effective cross-sectional area of the opening to increase or decrease air flow over the radiator based on a temperature of the coolant and an ambient air temperature.

Abstract: A climate control system including an air controller switchable between fresh air, recirculated air, and partial recirculated air modes is disclosed. The system further includes a control module connected to the controller and a link operatively connecting the washer fluid system and the module. When the washer fluid system is activated, the module switches the controller from the fresh air mode to the recirculated air mode, preventing washer fluid odors from entering the vehicle cabin while the washer fluid system is activated. The module can also selectively switch the air controller between fresh, recirculated, and partial recirculated air modes based on condition inputs. Non-limiting examples of condition inputs include a fog look-up table, wet bulb level, humidity level, air quality level, and temperature level. The module directs the air controller to switch to the fresh air mode based on information generated by one or more of the condition inputs.

Abstract: Methods and systems for electric vehicles, such as a battery electric vehicle (BEV) and a plug-in hybrid electric vehicle (PHEV), include pre-cooling a traction battery of the vehicle upon an indication that the vehicle is being driven to a charging station. The pre-cooling is done by an on-board battery cooling system. The pre-cooling depends on the distance between the vehicle and the charging station.

Abstract: Cooling of a battery pack of an electrified vehicle is performed with an optimized energy usage and with minimal impact on cooling of the passenger cabin. The battery is actively cooled by circulating coolant from the battery to a chiller of an air conditioning system when a battery temperature is above a predetermined power-limiting temperature. The battery is passively cooled by circulating coolant from the battery to a radiator when the battery temperature is between a first threshold and the power-limiting temperature and a difference between a battery coolant temperature and an ambient air temperature is greater than a predetermined difference. The battery is actively cooled using the chiller when the battery temperature is between the first threshold and the power-limiting temperature and the difference between the battery coolant temperature and the ambient air temperature is less than the predetermined difference.

Abstract: Vehicle climate control systems include heating, ventilating and air conditioning (HVAC) systems for adjusting the vehicle cabin temperature. The HVAC system can deliver heated or cooled air to the vehicle interior to achieve a desired temperature inside the vehicle cabin. Some vehicles are equipped with secondary comfort features, such as heated or cooled seats, for additionally addressing occupant comfort. These features are typically stand-alone devices that function separately from the HVAC system.
