    Abstract: A system for a vehicle includes an air conditioning compressor, and a controller configured to operate the compressor based on temperature value, responsive to the temperature values being faulty and refrigerant pressure values exceeding a first threshold, operate the compressor based on the refrigerant pressure values, and responsive to the refrigerant pressure values falling below a second threshold, deactivate the compressor for a rest of a drive cycle.

    Abstract: A vehicle includes a temperature control system, a battery configured to power the temperature control system, and a controller. The controller is programmed to, in response to a request to precondition the battery or the cabin air, an absence of receiving a signal indicative of a desired initial battery state of charge, and an actual battery state of charge being greater than a default threshold, deliver electrical power from the battery to the temperature control system at a desired value. The controller is further programmed to, in response to the request to precondition the battery or the cabin air, receiving the signal indicative of the desired initial battery state of charge, and the actual battery state of charge being greater than the desired initial battery state of charge but less than the default threshold, deliver electrical power from the battery to the temperature control system at the desired value.

    Abstract: A thermal system for an electrified vehicle including a thermal loop and a controller is provided. The thermal loop may include a rear evaporator and a compressor fluidly connected thereto, a conduit to distribute oil throughout the thermal loop, and an evaporator valve. The controller may be programmed to, responsive to receipt of a signal indicating evaporator valve shut-off and detection of a vehicle plug-in event, cycle the compressor to promote oil movement through the compressor. The controller may be further programmed to, responsive to receipt of the signal, open the evaporator valve to force oil back to the compressor. The thermal loop may further include a first expansion valve up stream of a chiller fluidly connected to the compressor, a second expansion valve between the evaporator valve and the rear evaporator, and a third expansion valve up stream of a front evaporator fluidly connected to the compressor.

    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.
