BATTERY THERMAL CONTROLS FOR BATTERIES USED IN ELECTRIC VEHICLES AND POWER WALL APPLICATIONS

A method includes implementing an inverted degradation model to determine an optimal battery core temperature. The inverted degradation model receives as inputs one or more of a power state value indicating whether the battery is currently in a high-power state or a low power state, a battery temperature value representing a current battery core temperature, a battery degradation value representing a battery degradation status, a battery age indicator representing a current age of the battery, a state of charge value representing a remaining battery charge and a battery current load value representing a current draw from the battery by the electric vehicle. The inverted degradation model outputs a desired battery core temperature value. The method includes operating the battery thermal system in order to achieve the desired battery core temperature.
