Abstract

A server includes an interface configured to communicate with a vehicle and a charger, and a processor configured to responsive to receiving, from the vehicle, vehicle data indicative of an energy transfer amount from the vehicle to one or more receiving entities above a transfer threshold, impose a limitation on the charger to charge the vehicle by sending a message to the charger.

First claim

What is claimed is:

1 . A server, comprising:
an interface configured to communicate with a vehicle and a charger; and a processor configured to:
responsive to receiving, from the vehicle, vehicle data indicative of an energy transfer amount from the vehicle to one or more receiving entities above a transfer threshold, impose a limitation on the charger to charge the vehicle by sending a message to the charger.

2 . The server of claim 1 , wherein the limitation includes a reduction of charging amount to charge the vehicle using the charger.

3 . The server of claim 1 , wherein the limitation includes an increased price for charging the vehicle using the charger, and the processor is further configured to:
calculate the increased price using an amount of electricity transferred above the transfer threshold.

4 . The server of claim 1 , wherein the processor is further configured to:
responsive to receiving vehicle data indicative of the energy transfer amount from the vehicle to the one or more receiving entities exceeding the transfer threshold, impose a vehicle limitation on the vehicle to reduce the transfer threshold for a future timeframe.

5 . The server of claim 1 , wherein the processor is further configured to:
responsive to the one or more receiving entities include an authorized entity and an unauthorized entity, determine the energy transfer amount without taking into account an amount of energy transferred to the authorized entity.

6 . The server of claim 1 , wherein the vehicle data is further indicative of driving operations of the vehicle, and the processor is further configured to:
responsive to detecting an excessive driving, revise the limitation, wherein the excessive driving includes a driving distance above a distance threshold.

7 . The server of claim 6 , wherein the excessive driving further includes vehicle driving operations outside a geofence, or outside a predefined timeframe.

8 . The server of claim 1 , wherein the processor is further configured to:
responsive to detecting a replenishment of electric charge for an amount of energy transferred above the transfer threshold using an energy source other than the charge, remove the limitation.

9 . A charger comprising:
a connector configured to provide electric charge to a vehicle; and a controller, programmed to:
record a first mileage and a first energy amount of the vehicle at an end of a first charge event,
responsive to detecting the vehicle connecting to the connector to perform a second charge event, obtain a second milage and a second energy amount of the vehicle,
calculate a driving distance between the first charge event and the second charge event by comparing the second milage with the first mileage,
calculate an expected energy amount using the driving distance,
calculate an actual energy amount by comparing the first energy amount with the second energy amount, and
responsive to detecting the actual energy amount being higher than the expected energy amount by a predetermined threshold, impose a limitation to charge the vehicle during the second charge event.

10 . The charger of claim 9 , wherein the limitation includes a charging amount reduction to charge the vehicle during the second charge event.

11 . The charger of claim 9 , wherein the limitation includes an increased price for charging the vehicle, the controller is further programmed to:
calculate the increased price using a difference between the expected energy amount and the actual energy amount.

12 . The charger of claim 9 , wherein the controller is further programmed to:
determine a distance allowance of the vehicle by receiving vehicle data from the vehicle, wherein the vehicle data is indicative of an identification of a vehicle user determined via a biometric input.

13 . The charger of claim 9 , further comprising:
a wireless transceiver configured to communicate with the vehicle via a wireless connection.

14 . The charger of claim 9 , wherein the controller is further programmed to:
responsive to detecting the driving distance being above a distance allowance, increase the limitation to charge the vehicle during the second charge event.

15 . The charger of claim 9 , wherein the controller is further programmed to:
calculate an extra energy amount using a difference between the expected energy amount and the actual energy amount; and responsive to detecting a replenishment energy amount received by the vehicle using an energy source other than the charge and greater than the extra energy amount, remove the limitation.

16 . A method comprising:
receiving, from a vehicle, vehicle data indicative of driving operations of the vehicle and an energy transfer from the vehicle to one or more receiving entities; and responsive to the vehicle data being indicative of excessive driving and the energy transfer being above a transfer threshold, imposing a limitation on a charger to charge the vehicle.

17 . The method of claim 16 , wherein the excessive driving is indicative of a driving distance above a distance threshold during a predefined time period.

18 . The method of claim 17 , wherein the limitation includes an increased price for charging the vehicle using the charger, the method further comprising:
calculating a total extra energy amount based on the driving distance above the distance threshold and an amount of energy transfer above the transfer threshold; and calculating the increased price using the total extra energy amount of energy.

19 . The method of claim 18 , further comprising:
responsive to the one or more receiving entities include both an authorized entity and an unauthorized entity, determine the total extra energy amount without taking into account an amount of energy transferred to the authorized entity.

20 . The method of claim 16 , further comprising:
responsive to detecting a replenishment of electric charge on the vehicle using an energy source other than the charger, reduce the limitation.
