1. A method of controlling a state-of-charge (SOC) of a vehicle battery, comprising the steps of:

  • (a) generating a battery temperature prediction for the vehicle battery;

    (b) using the battery temperature prediction to determine a desired SOC range for the vehicle battery that includes an upper SOC limit, a lower SOC limit, or both, wherein the desired SOC range is at least somewhat temperature dependent; and

    (c) controlling the amount of charge on the vehicle battery so that the SOC of the vehicle battery is generally maintained within the desired SOC range.
