Techniques for estimating battery system power capability using machine learning models and search algorithms

A state of power (SOP) estimation method for an electrified vehicle, the SOP estimation method comprising:

• accessing, by a control system of the electrified vehicle, a trained battery voltage estimation model configured to estimate a voltage of a battery system of the electrified vehicle based on a set on input parameters including at least state of charge (SOC), temperature, and power or current;
• performing, by the control system, a search process to determine a final estimated SOP that causes the estimated voltage of the battery system to fall within a desired voltage range;
• and
• controlling, by the control system, the electrified vehicle based on the final estimated SOP of the battery system.
