1. A method comprising:

  • receiving, from an electric vehicle charging station network server over a network, a first list that includes a first plurality of identifiers that identify a first plurality of electric vehicle operators respectively, wherein the first list is applicable to a first time period of a day;

    receiving, from the electric vehicle charging station network server over the network, a second list that includes a second plurality of identifiers that identify a second plurality of electric vehicle operators respectively, wherein the second list is applicable to a second time period of the day, wherein the first time period of the day and the second time period of the day are different;

    receiving, during the first time period of the day, a first charging session request that requests a first charging session between a first electric vehicle and the electric vehicle charging station, wherein the first charging session request includes a first identifier that identifies a first electric vehicle operator;

    determining to compare the first identifier against the received first list as a result of the first charging session request being received during the first time period of the day;

    comparing the first identifier against the received first list as a result of determining to compare the first identifier against the received first list;

    granting the first charging session based on the comparison of the first identifier against the received first list, wherein the comparison determines that the first identifier identifies an electric vehicle operator who is allowed use of the electric vehicle charging station, and wherein the granted first charging session allows the first electric vehicle to be charged via the electric vehicle charging station;

    receiving, during the first time period of the day, a second charging session request that requests a second charging session between a second electric vehicle and the electric vehicle charging station, wherein the second charging session request includes a second identifier that identifies a second electric vehicle operator;

    determining to compare the second identifier against the received first list as a result of the second charging session request being received during the first time period of the day;

    comparing the second identifier against the received first list as a result of determining to compare the second identifier against the received first list;

    rejecting the second charging session based on the comparison of the second identifier against the received first list, wherein the comparison determines that the second identifier identifies an electric vehicle operator who is not authorized to use the electric vehicle charging station;

    receiving, during the second time period of the day, a third charging session request that requests a third charging session between the second electric vehicle and the electric vehicle charging station, wherein the third charging session request includes the second identifier;

    determining to compare the second identifier against the received second list as a result of the third charging session request being received during the second time period of the day;

    comparing the second identifier against the received second list as a result of determining to compare the second identifier against the received second list; and

    granting the third charging session based on the comparison of the second identifier against the received second list, wherein the comparison determines that the second identifier identifies an electric vehicle operator who is authorized to use the electric vehicle charging station at a time when the third charging session request is received, and wherein the granted third charging session allows the second electric vehicle to be charged via the electric vehicle charging station.
