The charging station includes a charging control module to control a charging process between a charging point of the charging station and an electric vehicle connectable to the charging point at least based on a configuration data set comprising a charging configuration parameter. The backend system includes a multiplex module connectable to a configuration memory module. The configuration memory module stores a plurality of time dependent configuration data sets. The multiplex module determines a time dependent configuration data set upon receipt of a configuration request message emitted by the charging station based on a time specification of the configuration request message. The multiplexing module is configured to cause a transmitting of the determined configuration data set to the charging station. The charging control module configured to control the charging process based on the received configuration data set. ## Claims ### Claim 1 Charging system for electric vehicles, comprising: at least one backend system, at least one charging station comprising at least one charging control module configured to control a charging process between at least one charging point of the charging station and an electric vehicle connectable to the charging point at least based on a configuration data set comprising at least one charging configuration parameter, wherein the backend system comprises at least one multiplex module connectable to a configuration memory module, wherein the configuration memory module stores a plurality of time dependent configuration data sets, wherein the multiplex module is configured to determine a time dependent configuration data set upon receipt of a configuration request message emitted by the charging station based on at least one time specification of the configuration request message, wherein the multiplexing module is configured to cause a transmitting of the determined configuration data set to the charging station, and wherein the charging control module is configured to control the charging process based on the received configuration data set. ### Claim 2 (depends on 1) Charging system according to claim 1, wherein the charging station comprises a request module configured to cause an emitting of a configuration request message upon a detection of a trigger information, wherein the trigger information is a charging request received by the charging station from an electric vehicle to be charged. ### Claim 3 (depends on 1) Charging system according to claim 1, wherein the backend system comprises a first time module configured to provide an instantaneous time specification, wherein the time of receipt of the configuration request message is determined as the time specification by means of the first time module. ### Claim 4 (depends on 3) Charging system according to claim 3, wherein the charging system comprises at least one master device connectable to at least the backend system, wherein the master device is configured to synchronize the first time module with a master time module of the master device, wherein the master device is, in particular, configured to synchronize the first time module at predeterminable time points. ### Claim 5 (depends on 1) Charging system according to claim 1, wherein the charging station comprises at least one second time module, and the charging station comprises a request module configured to integrate the instantaneous time specification provided by the second time module into a configuration request message as a time specification of the configuration request message. ### Claim 6 (depends on 5) Charging system according to claim 5, wherein the charging system comprises at least one master device connectable to at least the charging station, wherein the master device is configured to synchronize the second time module with a master time module of the master device, wherein the master device is, in particular, configured to synchronize the second time module at predeterminable times. ### Claim 7 (depends on 1) Charging system according to claim 1, wherein the configuration memory module is configured to store a configuration assignment table, wherein a specific time range, in particular, a day time range, is assigned to each configuration data set in the configuration assignment table. ### Claim 8 (depends on 7) Charging system according to claim 7, wherein the multiplex module is configured to determine a configuration data set assigned with a specific time range by comparing the time specification with the time ranges provided in the configuration assignment table such that the configuration data set is determined which is assigned with the time range that corresponds to the time specification. ### Claim 9 (depends on 1) Charging system according to claim 1, wherein the backend system comprises at least one stamping module configured to integrate time lapse specification into a message containing the configuration data set, wherein the time lapse specification represents the validity period of the configuration data set. ### Claim 10 (depends on 1) A method for operating a charging system, in particular, a charging system according to claim 1, comprising at least one backend system and at least one charging station for charging electric vehicles, the method comprising: determining, by a multiplex module of the backend system, a time dependent configuration data set stored in a configuration memory module of the backend system upon receipt of a configuration request message emitted by the charging station based on at least one time specification of the configuration request message, causing, by the multiplexing module, a transmitting of the determined configuration data set to the charging station; and controlling, by a charging control module of the charging station, a charging process based on the received configuration data set.
