Abstract

A vehicle may include a battery that receives energy from a charge station remote from the vehicle, and a controller. The controller may request that the station provide information about an electrical parameter associated with energy being supplied by the station, may determine information about an electrical parameter associated with energy received by the battery, and may prevent the battery from further receiving energy if the provided information is different than the determined information.

Claims

1. A vehicle comprising:

a traction battery;

a battery charger configured to receive energy from a charge station remote from the vehicle and to provide energy to the battery; and

one or more controllers configured to initiate charging of the battery and to notify the charge station if the power, voltage or current measured and reported by the charge station is not approximately equal to the power, voltage or current measured at the battery charger.

2. The vehicle of claim 1 wherein the one or more controllers are further configured to permit the battery charger to further receive energy from the charge station if the power, voltage or current measured and reported by the charge station is approximately equal to the power, voltage or current measured at the battery charger.

3. A method for authenticating a charge station comprising:

establishing communications with the charge station;

requesting that the charge station supply energy to a battery charger; and

notifying the charge station in response to the power, voltage or current measured and reported by the charge station not being approximately equal to the power, voltage or current measured at the battery charger.

4. The method of claim 3 further comprising permitting the battery charger to further receive energy from the charge station if the power, voltage or current measured and reported by the charge station is approximately equal to the power, voltage or current measured at the battery charger.

5. A vehicle comprising:

a battery configured to receive, via a battery charger, energy from a charge station remote from the vehicle; and

a controller configured to initiate charging of the battery and to notify the charge station if an electrical parameter measured and reported by the charge station is not approximately equal to a same electrical parameter measured at the battery charger.

6. The vehicle of claim 5 wherein the controller is further configured to permit the battery to further receive energy if the electrical parameter measured and reported by the charge station is approximately equal to the same electrical parameter measured at the battery charger.

7. The vehicle of claim 5 wherein the electrical parameter is power.

8. The vehicle of claim 5 wherein the electrical parameter is voltage.

9. The vehicle of claim 5 wherein the electrical parameter is current.

10. A power system for an automotive vehicle comprising:

a battery; and

at least one controller configured to command a charge station to provide energy to the battery at a specified power, voltage, or current, and to notify the charge station if the power, voltage or current from the charge station measured at the battery is different than the specified power, voltage or current.

11. The system of claim 10 wherein the at least one controller is further configured to permit the charge station to continue to provide energy to the battery if the power, voltage or current from the charge station measured at the battery is not different than the specified power, voltage or current.

12. The system of claim 10 wherein the at least one controller is further configured to command the charge station to provide energy to the battery for a specified period of time.

13. The system of claim 12 wherein the at least one controller is further configured to request information from the charge station about the power, voltage or current from the charge station during the specified period of time.
