Abstract

This disclosure provides a method, performed in a payment unit 30,30′ in a vehicle having an energy storage, of controlling an amount available for payment. The method comprises: determining S1 a state of charge of the energy storage of the vehicle, and calculating S2 the amount to be available for payment based on the determined state of charge of the energy storage.

Claims

1. A method, performed in a payment unit in a vehicle having an energy storage, of controlling an amount to be available for payment, the method comprising:

determining a state of charge of the energy storage of the vehicle;

calculating the amount to be available for payment based on the determined state of charge of the energy storage.

2. The method according to claim 1, wherein the step of calculating the amount to be available for payment comprises estimating an amount required for fully replenishing the energy storage of the vehicle based on at least the determined state of charge of the energy storage.

3. The method according to claim 1, further comprising:

obtaining a maximum quantity of energy storable at the energy storage;

wherein the step of calculating the amount to be available for payment comprises calculating the amount based on a difference between the maximum quantity of energy and the determined state of charge of the energy storage.

4. The method according to claim 1, further comprising:

determining energy price information; and

wherein the step of calculating the amount to be available for payment is further based on the determined energy price information.

5. The method according to claim 4, wherein the step of determining energy price information comprises obtaining energy price information.

6. The method according to claim 1, further comprising:

transferring an amount between a first payment area and a second payment area, so that the calculated amount is available in the second payment area which comprises the amount to be available for payment.

7. The method according to claim 6, wherein the first payment area and the second payment area are comprised in a secure area.

8. The method according to claim 6, wherein a security level of the second payment area is lower than the security level of the first payment area.

9. The method according to claim 6, wherein at least one of the first payment area and the second payment area is a digital wallet.

10. The method according to claim 1, wherein the payment unit is embedded in the vehicle.

11. The method according to claim 6, wherein the first payment area comprises a first amount transferred from a remote user account, and the second payment area comprises a second amount, the second amount being adjusted using a transfer to or from the first payment area in order for the second amount to comprise the amount to be available for payment.

12. The method according to claim 5, further comprising:

charging energy on the energy storage at an energy provider;

receiving from the energy provider a request for payment of the energy charged on the energy storage, the request for payment comprising an amount to be paid corresponding to the energy charged on the energy storage;

authenticating the energy provider; and

if the energy provider is authenticated successfully, communicating to the energy provider information enabling the payment of the amount to be paid from the calculated payment amount available in the second payment area.

13. The method according to claim 1, wherein the step of calculating an amount to be available for payment is further based on contextual data stored in a remote database.

14. The method according to claim 13, wherein the contextual data comprises at least one of:

a distance, a time, a speed, location information, and a maximum quantity of energy storable on the energy storage.

15. The method according to claim 1, wherein calculating an amount to be available for payment is performed periodically or at a predetermined incremental event of depletion of the energy storage.

16. The method according to claim 1, wherein the amount to be available for payment is in a digital currency.

23. An integrated circuit card configured to perform the method of claim 1.

25. A computer program comprising a non-transitory computer readable medium comprising computer readable code which, when run on a controller of a payment unit, causes the payment unit to perform the method as claimed in claim 1.

17. A payment unit for controlling an amount available for payment in an vehicle having an energy storage, the payment unit comprising:

a controller configured to;

determine a state of charge of the energy storage of the vehicle; and

calculate the amount to be available for payment based on the determined state of charge of the energy storage.

18. The payment unit according to claim 17, wherein the controller is further configured to obtain a maximum quantity of energy storable at the energy storage;

wherein the controller is further configured to perform the step of calculating the amount to be available for payment based on the difference between the maximum quantity of energy and the determined state of charge of the energy storage.

19. The payment unit according to claim 17, wherein the controller is further configured to determine energy price information;

and wherein the controller is further configured to perform the step of calculating the amount to be available for payment based on the determined energy price information.

20. The payment unit according to claim 17, wherein the controller is further configured to transfer an amount between a first payment area and a second payment area so that the calculated amount is available in the second payment area which comprises the amount to be available for payment.

21. The payment unit according to claim 20, wherein the first payment area and the second payment area are comprised in a secure area.

22. The payment unit according to claim 17, further comprising:

a data storage configured to store the amount to be available for payment;

an interface configured to receive from the energy provider a request for payment of the energy charged on the energy storage, the request for payment comprising an amount to be paid corresponding to the energy charged on the energy storage;

the controller is further configured to authenticate the energy provider;

If the energy provider is authenticated successfully, the interface is further configured to communicate to the energy provider information enabling the payment of the amount to be paid from the calculated amount available in the second payment area.

24. A vehicle comprising a payment unit according claim 17.
