Abstract

A vehicle is provided with a motor that is connected to a storage device. The motor is configured to provide drive torque and the storage device is configured to receive power from an external supply for facilitating charging. The vehicle also includes a user interface and a controller. The user interface is configured to provide a charge level selection. The controller is configured to receive input that is indicative of a present charge value. The controller is further configured to disable charging when the present charge value corresponds to the charge level selection.

Claims

1. A vehicle comprising:

a motor configured to provide drive torque;

a storage device connected to the motor and configured to receive power from an external supply for facilitating charging;

a climate control system configured to heat and cool at least one of a passenger compartment and the storage device;

a user interface configured to provide a charge level selection; and

at least one controller configured to;

receive input indicative of a present charge value, an identity of a present driver from a key, an ambient temperature, and a climate control system power consumption, disable charging when the present charge value corresponds to the charge level selection; and

modify the charge level selection based on historic climate control system power consumption associated with the present driver and the ambient temperature.

2. The vehicle of claim 1 wherein the controller is further configured to disable charging when the present charge value corresponds to a value that is between 80% and 120% of the charge level selection.

3. The vehicle of claim 1 wherein the user interface further comprises a portable device that is configured to wirelessly communicate with the controller, and wherein the user interface is further configured to provide a travel distance associated with a subsequent trip;

wherein the controller is further configured to modify the charge level selection based on the travel distance.

4. The vehicle of claim 1 wherein the user interface is further configured to display at least two charge level selection elements corresponding to an available range of charge level selection values.

5. The vehicle of claim 1 wherein the user interface is further configured to display a gage with a first indicator corresponding to the charge level selection and a second indicator corresponding to the present charge value.

6. The vehicle of claim 1 further comprising:

a charger configured to receive AC power from the external supply and to provide DC power to the storage device;

wherein the controller is further configured to;

receive input indicative of a charging cost associated with the external supply, and a charging rate associated with the charger, and

delay charging based on the charging cost and the charging rate.

7. The vehicle of claim 1 wherein the controller is further configured to:

receive input indicative of an identity of a present driver and motor power consumption; and

modify the charge level selection based on historic motor power consumption associated with the present driver.

8. The vehicle of claim 1 further comprising:

a navigation system configured to;

receive input indicative of a target location from the user interface,

receive input indicative of a present location, and travel information from an external network, and

provide output indicative of a travel distance between the present location and the target location based on the travel information;

wherein the controller is further configured to;

receive input indicative of motor power consumption, and

modify the charge level selection based on estimated motor power consumption associated with the travel distance.

9. A vehicle system comprising:

a battery configured to receive power from an external supply for charging thereof; and

at least one controller configured to;

receive input indicative of a customer state of charge (CSOC) selection,

a present CSOC value of the battery, an identity of a present driver from a key, an ambient temperature, and a climate control system power consumption,

disable charging when the present CSOC value corresponds to a charging limit, the charging limit being based on the CSOC selection, and

modify the charging limit based on historic climate control system power consumption associated with the present driver and the ambient temperature.

10. The vehicle system of claim 9 wherein the controller is further configured to:

receive input indicative of a charging cost associated with the external supply; and

delay charging until the charging cost decreases below a predetermined threshold value.

11. The vehicle system of claim 9 wherein the controller is further configured to:

receive input indicative of an identity of a present driver and motor power consumption; and

modify the charging limit based on historic motor power consumption associated with the present driver.

12. The vehicle system of claim 9 wherein the controller is further configured to:

receive input indicative of motor power consumption, and a travel distance between a present vehicle location and a target vehicle location; and

modify the charging limit based on estimated motor power consumption associated with the travel distance.

13. A method for controlling electric vehicle charging comprising:

enabling charging of a storage device;

receiving input indicative of a charging limit, a present charge value, an identity of a present driver from a key, an ambient temperature, and a climate control system power consumption;

disabling charging when the present charge value corresponds to the charging limit; and

modifying the charging limit based on historic power consumption associated with the present driver and the ambient temperature.

14. The method of claim 13 further comprising:

receiving input indicative of a charging cost associated with an external power supply; and

delaying charging until the charging cost decreases below a predetermined threshold value.

15. The method of claim 13 further comprising:

receiving input indicative of an identity of a present driver and motor power consumption; and

modifying the charging limit based on historic motor power consumption associated with the present driver.

16. The method of claim 13 further comprising:

receiving input indicative of motor power consumption, and a travel distance between a present vehicle location and a target vehicle location; and

modifying the charging limit based on estimated motor power consumption associated with the travel distance.

17. The method of claim 13 further comprising:

displaying a gage with a first indicator corresponding to the charging limit and a second indicator corresponding to the present charge value.
