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.
