    Abstract: A method of determining battery power capability may include: determining a circuit model for a battery, including a first resistance (r1) in series with a second resistance (r2) and a capacitance (C) in parallel; setting upper and lower limits for r1, r2 and C based on a battery temperature a battery state of charge or both; applying an EKF to determine r1, r2 and C within the set upper and lower limits; and outputting the battery power capability based on r1, r2 and C. The upper and lower limits may be adjusted based on the age of the battery.

    Abstract: A vehicle is provided with a vehicle system having an electric machine and a battery. The electric machine is configured to provide drive torque and the battery supplies power to the electric machine. The vehicle also includes a controller that is configured to generate output indicative of at least one of a battery power capability and a battery state of charge using a filter having a variable EKF gain factor based on battery temperature.
