Abstract

A method according to an exemplary aspect of the present disclosure includes, among other things, controlling charging of a battery pack of an electrified vehicle over a plurality of charging locations of a drive route, the controlling step including scheduling charging based at least on a cost to charge at each of the plurality of charging locations and an amount of charging time available at each of the plurality of charging locations.

Claims

1. A method to control charging of a battery pack of an electrified vehicle over a plurality of charging locations of a drive route, comprising:

charging the vehicle at each of the plurality of charging locations based at least on a cost to charge at each of the plurality of charging locations and an amount of charging time available at each of the plurality of charging locations.

2. The method as recited in claim 1, wherein controlling the charging includes determining a drive route expected to be traveled by the electrified vehicle.

3. The method as recited in claim 2, wherein determining the drive route includes inferring the drive route based on historical route information associated with the electrified vehicle.

4. The method as recited in claim 2, comprising determining a location of each of the plurality of charging locations that are available along the drive route.

5. The method as recited in claim 4, comprising determining the cost to charge associated with each of the plurality of charging locations.

6. The method as recited in claim 4, comprising creating a charging schedule for charging the battery pack along the drive route, the charging schedule including instructions for prioritizing charging at a first charging location of the plurality of charging locations over charging at a second charging location of the plurality of charging locations.

7. The method as recited in claim 6, wherein controlling the charging includes prioritizing charging at the first charging location if the cost to charge at the first charging location is less than the cost to charge at the second charging location.

8. The method as recited in claim 1, wherein controlling the charging includes executing a charge optimization sequence for determining an amount of charging that is to occur for charging the battery pack at each of the plurality of charging locations.

9. The method as recited in claim 8, wherein the charge optimization sequence includes creating a charging schedule for charging at each of the plurality of charging locations.

10. The method as recited in claim 9, comprising determining a Route Confidence Value and an SOC Safety Margin for a remaining portion of the drive route upon arriving at a first charging location of the drive route.

11. The method as recited in claim 10, comprising determining whether the first charging location is a cheapest charging location along the drive route.

12. The method as recited in claim 11, comprising charging the battery pack to a 100% SOC if the first charging location is the cheapest charging location along the drive route.

13. The method as recited in claim 11, comprising calculating a distance to a next cheapest charging location if the first charging location is not the cheapest charging location along the drive route.

14. The method as recited in claim 13, comprising charging the battery pack to a target SOC that is sufficient to travel the distance to a next cheapest charging location.

15. The method as recited in claim 14, comprising:

determining a 95% Confidence Charge Time associated with both the first charging location and the next cheapest charging location.

16. A vehicle system, comprising:

a battery pack;

a charging system configured to selectively charge the battery pack; and

a control system configured with instructions for prioritizing charging of the battery pack at a first charging station along a drive route over charging at a second charging station of the drive route.

17. The vehicle system as recited in claim 16, comprising a navigation system configured to communicate information regarding the drive route to the control system.

18. The vehicle system as recited in claim 16, wherein the control system includes at least one control module configured to execute a charge optimization sequence for charging the battery pack along the drive route.

19. The vehicle system as recited in claim 16, wherein the charging system includes a switch selectively actuated to shut-off charging of the battery pack.

20. The vehicle system as recited in claim 16, wherein said control system is configured to prepare the charging schedule based at least on a cost to charge at each of the first charging location and the second charging location and an amount of charging time available at each of the first charging location and the second charging location.
