Abstract: A system and method for managing thermal energy of a vehicle having a battery and an electric propulsion system are provided. The system monitors a current battery temperature, calculates an actual average battery temperature, and compares the calculated actual average battery temperature to a target lifetime battery temperature. If the actual average battery temperature is greater than the target lifetime battery temperature, and the current battery temperature is greater than the target lifetime battery temperature, the system cools the battery to below the current battery temperature. However, if the actual average battery temperature is less than the target lifetime battery temperature, and the current battery temperature is greater than the target lifetime battery temperature, the system delays cooling the battery. Therefore, the system may avoid expending energy to cool the battery in certain conditions.

Abstract: A method for managing thermal energy of a vehicle having a battery and an electric propulsion system is provided. The system monitors a current battery temperature, after the vehicle is connected to an outside power source at a plug time, and determines an outside air temperature. The system predicts a cabin heating temperature for a subsequent drive cycle. The subsequent drive cycle occurs when the vehicle is no longer connected to the outside power source. If the predicted cabin heating temperature is greater than the outside air temperature, the system heats the battery to a thermal storage temperature that is greater than a target operating temperature of the battery. Therefore, thermal energy is stored within the battery, and may be transferred to heat the cabin.
