Method and Apparatus For a Vehicle and a Server

A computer-implemented method for communicating provisioning certificates between a vehicle and two servers, the method comprising:

• receiving a first signal at a first server, wherein the first signal indicates that a new primary user has logged onto the vehicle;
• and
• transmitting, on a basis of the first signal, at least one second signal to a second server, wherein the at least one second signal indicates that a provisioning certificate for charging contracts which is associated with the vehicle is to be deleted, and that a new provisioning certificate is to be added, wherein the new provisioning certificate is identical to the provisioning certificate which is to be deleted.

A computer-implemented method for determining charging contracts for a vehicle, which method comprises:

• acquisition of a user input, wherein the user input indicates that a new primary user has logged onto the vehicle;
• and
• invalidation of charging contracts which are associated with the vehicle by transmission, on a basis of the user input, of a signal to a server, wherein the signal indicates that a new primary user has logged onto the vehicle.
