Abstract
Networked electric vehicle charging stations for charging electric vehicles are coupled with an electric vehicle charging station network server that performs authorization for charging session requests while the communication connection between the charging stations and the server are operating correctly. When the communication connection is not operating correctly, the networked electric vehicle charging stations enter into a local authorization mode to perform a local authorization process for incoming charging session requests.
Claims21
A non-transitory machine-readable storage medium that provides instructions that, if executed by a processor of an electric vehicle charging station, will cause said processor to perform operations 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;
- comparing the first identifier against the received first list, wherein determining to compare the first identifier against the first list is a result of the first charging session request being received during the first time period of the day;
- 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 that the first electric vehicle operator 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 second 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;
- comparing the second identifier against the received second list, wherein determining to compare the second identifier against the second list is a result of the second charging session request being received during the second time period of the day;
- determining that the comparison of the second identifier against the received second list does not indicate that the second electric vehicle operator is allowed use of the electric vehicle charging station;
- responsive to the determining that the comparison of the second identifier against the received second list does not indicate that the second electric vehicle operator is allowed use of the electric vehicle charging station, generating and transmitting a first charging session authorization request to the electric vehicle charging station network server, wherein the first charging session authorization request includes the second identifier;
- receiving a first charging session authorization reply from the electric vehicle charging station network server that indicates that the second electric vehicle operator is allowed use of the electric vehicle charging station;
- and
- granting the second charging session as indicated by the received first charging session authorization reply, wherein the granted second charging session allows the second electric vehicle to be charged via the electric vehicle charging station.

A method in an electric vehicle charging station, 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;
- comparing the first identifier against the received first list, wherein determining to compare the first identifier against the first list is a result of the first charging session request being received during the first time period of the day;
- 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 that the first electric vehicle operator 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 second 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;
- comparing the second identifier against the received second list, wherein determining to compare the second identifier against the second list is a result of the second charging session request being received during the second time period of the day;
- determining that the comparison of the second identifier against the received second list does not indicate that the second electric vehicle operator is allowed use of the electric vehicle charging station;
- responsive to the determining that the comparison of the second identifier against the received second list does not indicate that the second electric vehicle operator is allowed use of the electric vehicle charging station, generating and transmitting a first charging session authorization request to the electric vehicle charging station network server, wherein the first charging session authorization request includes the second identifier;
- receiving a first charging session authorization reply from the electric vehicle charging station network server that indicates that the second electric vehicle operator is allowed use of the electric vehicle charging station;
- and
- granting the second charging session as indicated by the received first charging session authorization reply, wherein the granted second charging session allows the second electric vehicle to be charged via the electric vehicle charging station.
