Method for controlling the activation (41) of a service function (23) depending on the usage behavior of a user of an
electric vehicle (10), wherein a request (29) to activate (41) the service function (23) is received by a control interface (28) of a service facility (24) which provides the service function (23), wherein an identification feature (12) which is assigned to the
electric vehicle (10) and for which the activation (41) is to take place is specified, and if the requested service (23) is unlocked, the service function (23) is activated by the service facility (24), characterized by the fact that Prior to the request for activation (41) by a computing device (26) at least one
energy exchange (22) of electrical energy (14) between the
electric vehicle (10) and a respective electric
charging station (13), an energy class (21) and an energy quantity (18) of the exchanged energy (14) are recorded, wherein the energy class (21) indicates a technology of an
energy source (20) which was used to generate the exchanged energy, and the technology indicates at least one of the following energy classes (21):
nuclear power,
hydropower,
wind power,
renewable energy,
coal power, and an addition value (33) is assigned to the respective
energy exchange (22) according to a predetermined evaluation rule (32) depending on the recorded energy class (21) and the recorded energy quantity (18), and the addition value (33) is added to a meter reading (35) assigned to the identification feature (12) in a data storage device (34), wherein the user's usage behavior with regard to the
energy source used (20) is linked in such a way that the service function (23) is activated more easily the more often an
energy source (20) of a certain technology is used and this is quantified by the evaluation rule (32) by issuing different addition values (33) for the same value of energy quantity (18), depending on the energy class used (21), and the technical
coupling between an
energy exchange (22) at the at least one
charging station (13) on the one hand and a control of the activation (41) of the service function (23) at the control interface (28) of the service facility (24) on the other hand is established by the requirement (36) is described by corresponding request data generated by the user, and the requirement (36) identifies the service function (23) and specifies the identification feature (12), and the service facility (24) for activating the service function (23) requires a threshold value (37) dependent on the service function (23) with respect to the meter reading (35) of the identification feature (12) and for this purpose transmits a request with respect to the meter reading (35) as a booking request with corresponding booking data specifying the threshold value (37) to a
control system (25) which has the computing device (26) for recording the energy class (21) and the energy quantity (18) via the control interface (28), and The service function (23) is only activated if the meter reading (35) is greater than the threshold value (37) that depends on the service function (23).
