A hybrid electric vehicle (HEV) and method of operation, which include a cabin, a battery, an emission aftertreatment catalyst, and a thermal management system coupled to a compressor and a chiller that each have cooling capacities and respective refrigerant and coolant distribution systems. The HEV also includes one or more controllers configured to precondition temperatures of the battery, cabin, and catalyst in response to a predicted vehicle start-time and/or a detected action that indicates likelihood of HEV start. The controller(s) utilize respective conditioning profiles for each of the battery, cabin, and catalyst to achieve the preconditioning temperatures at rates adjusted according to power availability from the battery and an external power source. The preconditioning is terminated upon HEV start or if the predicted start-time expires without HEV start. The HEV and method are adapted to learn from changes in actual start-times and driver actions resulting in HEV starts or no-starts.
