Abstract: This disclosure relates to an electrified vehicle having a control strategy for managing battery and cabin cooling. A corresponding method is also disclosed. An example electrified vehicle includes a cabin thermal management system configured to thermally condition a cabin of the electrified vehicle. The cabin thermal management system includes a compressor. The vehicle further includes a battery thermal management system configured to thermally condition a battery of the electrified vehicle, and a controller configured issue an instruction to reduce the speed of the compressor based, at least in part, on a speed of the electrified vehicle and a temperature of the battery.

Abstract: A vehicle thermal management system including a refrigerant circuit, a coolant circuit, a chiller, and a controller is provided. The refrigerant circuit may include an electric air conditioning (eAC) compressor and a pressure sensor. The coolant circuit may include a high-voltage battery. The chiller selectively thermally links the circuits. The controller may be programmed to, responsive to receipt of a sensor signal indicating refrigerant pressure exiting the eAC compressor is greater than a high threshold, output a pressure sensor fault error indicating the pressure sensor is faulty. The system may further include a timer to monitor operational timing of the eAC compressor. The controller may be further programmed to direct the system to operate without monitoring the eAC compressor responsive to the timer indicating the eAC compressor has been off for a time-period less than a time threshold reflective of the eAC compressor not being in an at rest state.

Abstract: While a speed of a first compressor during operation is less than a threshold speed, a speed of a second compressor during operation is prevented from falling below a minimum threshold speed that is defined by a sum of the speed of the first compressor and a predefined offset speed delta such that the minimum threshold speed changes as the speed of the first compressor changes.

Abstract: A vapor compression heat pump (VCHP) system for an electrified vehicle and a method for de-icing the VCHP system is provided. The electrified vehicle may include a vehicle cabin, the VCHP system, and a controller. The VCHP system may be in thermal communication with the cabin and include an outside heat exchanger and a compressor. The controller may be configured to, in response to detection of a predefined ice condition associated with the outside heat exchanger, output commands to adjust a speed of the compressor to influence a temperature of refrigerant flowing through the compressor such that the refrigerant carries an amount of heat sufficient to eliminate the predefined ice condition within a preselected time period. The predefined ice condition may be a condition in which the heat exchanger has accumulated ice or is likely to accumulate ice.
