Abstract

An exemplary method includes changing a scheduled preconditioning cycle of an electrified vehicle in response to a period without a key cycle of the electrified vehicle. Another exemplary method includes communicating an alert to an operator of an electrified vehicle in response to at least one preconditioning cycle of the electrified vehicle without a key cycle of the electrified vehicle.

First claim

We claim:

1 . A method, comprising:
changing a scheduled preconditioning cycle of an electrified vehicle in response to a period without a key cycle of the electrified vehicle.

2 . The method of claim 1 , wherein the changing comprises canceling the scheduled preconditioning cycle.

3 . The method of claim 1 , wherein the changing further comprises placing the electrified vehicle in an extended park mode.

4 . The method of claim 1 , further comprising alerting a user in response to the period without a key cycle prior to the changing.

5 . The method of claim 5 , further comprising automatically placing the electrified vehicle in an extended park mode if a threshold amount of time has passed after the alerting.

6 . The method of claim 1 , wherein the scheduled preconditioning cycle is configured to precondition a vehicle battery, a vehicle cabin, or both.

7 . The method of claim 1 , maintaining a battery temperature after the changing.

8 . The method of claim 1 , wherein the period is a time period that is greater than 72 hours.

9 . The method of claim 1 , further comprising waking the vehicle and starting a preconditioning cycle prior to the changing.

10 . The method of claim 9 , further comprising powering the preconditioning cycle using an energy source outside the vehicle.

11 . The method of claim 9 , further comprising receiving an input from the user to initiate the changing.

12 . A method, comprising:
communicating an alert to an operator of an electrified vehicle in response to at least one preconditioning cycle of the electrified vehicle without a key cycle of the electrified vehicle.

13 . The method of claim 12 , further comprising:
receiving an input from the operator in response to the alert; and discontinuing a scheduled preconditioning cycle in response to the input.

14 . The method of claim 12 , further comprising placing the electrified vehicle in an extended park mode in response to at least one preconditioning cycle without a key cycle of an electrified vehicle.

15 . The method of claim 12 , wherein the communicating is further in response to a time period without the key cycle of the electrified vehicle.

16 . The method of claim 15 , wherein the time period is 72 hours or more.

17 . The method of claim 12 , further comprising powering the at least one preconditioning cycle using a power source outside the vehicle.

18 . An electrified vehicle assembly, comprising:
an electrified vehicle controller that selectively initiates a preconditioning cycle within an electrified vehicle; and a transmitter that communicates an alert to an operator of an electrified vehicle in response to at least one preconditioning cycle without a key cycle of an electrified vehicle.

19 . The electrified vehicle of claim 18 , wherein the controller discontinues the preconditioning cycle in response to a receiving an input from the operator in response to the alert.

20 . The electrified vehicle of claim 18 , including a heater that heats a vehicle battery, a vehicle cabin, or both during the preconditioning cycle.
