21. A method for heating a battery in a vehicle having a battery heater, the method comprising:
-
determining a vehicle shut-down condition; enabling energy flow from the battery to the heater to heat the battery after determining the shut-down condition; and determining a period of time during which the shut-down condition has been active, wherein the enabling step includes preventing energy flow from the battery to the heater when the shut-down time period is greater than a non-use time period so as to limit battery drain when the vehicle is not in use for a prolonged period of time.

22. A method for heating a battery in a vehicle having a battery heater and a vehicle system controller, the method comprising:
-
determining a vehicle shut-down condition; and heating the battery by enabling energy flow from the battery to the heater after the vehicle controller determines the shut-down condition if; a battery temperature is less than a predefined battery temperature; a battery state of charge (SOC) is greater than a battery threshold SOC; and a predefined non-use period of time has not elapsed since determining the shut-down condition. - View Dependent Claims (23)
