3. The control system of claim 0, wherein the control unit determines a first duration of time until a preset drive time and a second duration of time required to bring the battery within the tolerance of the optimal battery temperature and activates the battery thermal conditioning system when the first duration equals the second duration.
-
8. The control system of claim 0, wherein the control unit:
-
calculates a first duration of time until a preset drive time, a second duration of time required to thermally condition the vehicle cabin to reach a preset cabin temperature, and a number of vehicle cabin conditioning events required to thermally condition the vehicle cabin to reach the preset cabin temperature; if the number of vehicle cabin conditioning events required is less than or equal to the number of vehicle cabin conditioning events enabled and the first duration of time is equal to or less than the second duration of time, begins conditioning the cabin; and if the number of vehicle cabin conditioning events required is greater than the number of vehicle cabin conditioning events enabled or the first duration of time is greater than the second duration of time, recalculates the first duration of time until a preset drive time, the second duration of time required to thermally condition the vehicle cabin to reach a preset cabin temperature, and the number of vehicle cabin conditioning events required to thermally condition the vehicle cabin to reach the preset cabin temperature.

10. A method of charging a battery comprising:
-
determining a first duration of time until a predetermined drive time, utilizing a control unit; determining a second duration of time required to charge the battery, utilizing the control unit; determining a first time to start charging the battery based on the first duration of time and the second duration of time, utilizing the control unit; and charging the battery at the first time, utilizing a battery charging system. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
