Abstract
A mobile device reads a near-field communication (NFC) tag of an electric vehicle supply equipment (EVSE). The NFC tag is encoded with an identifier of the EVSE. The mobile device transmits a charging session authorization request to a server to request authorization for a charging session at the EVSE, the request including the identifier of the EVSE and an access identifier of the electric vehicle operator. The server determines whether to grant authorization for the charging session. If granted, the server transmits a command to the EVSE to allow the charging session.
Claims30
A method, comprising:
- reading, by a mobile client device, a near-field communication (NFC) tag of an electric vehicle supply equipment (EVSE);
- decoding, by the mobile client device, the NFC tag to reveal an identifier of the EVSE;
- transmitting, by the mobile client device, a charging session authorization request to an electric vehicle charging network server to request authorization for a charging session at the EVSE, wherein the charging session authorization request includes:
- the identifier of the EVSE, and
- an access credential of an electric vehicle operator;
- and
- receiving, at the mobile client device, a message from the electric vehicle charging network server that indicates that the charging session has been authorized.
A method, comprising:
- encoding a unique identifier in a near-field communication (NFC) tag, wherein the unique identifier uniquely identifies an electric vehicle supply equipment (EVSE) to be connected to the NFC tag;
- receiving, from a mobile client device, a charging session authorization request that requests authorization to start a charging session at the EVSE, the charging session authorization request including an access credential of an electric vehicle operator and an identifier that identifies the EVSE;
- determining to authorize the charging session;
- responsive to the determining to authorize the charging session, transmitting a command to the EVSE to commence the charging session;
- and
- transmitting, to the mobile client device, a message that indicates that the charging session has been authorized.
A non-transitory machine-readable storage medium that provides instructions that, when executed by a processor, cause said processor to perform operations comprising:
- reading, by a mobile client device, a near-field communication (NFC) tag of an electric vehicle supply equipment (EVSE);
- decoding, by the mobile client device, the NFC tag to reveal an identifier of the EVSE;
- transmitting, by the mobile client device, a charging session authorization request to an electric vehicle charging network server to request authorization for a charging session at the EVSE, wherein the charging session authorization request includes:
- the identifier of the EVSE, and
- an access credential of an electric vehicle operator;
- and
- receiving, at the mobile client device, a message from the electric vehicle charging network server that indicates that the charging session has been authorized.

- receiving, from a mobile client device, a charging session authorization request that requests authorization to start a charging session at the EVSE, the charging session authorization request including an access credential of an electric vehicle operator and an identifier that identifies the EVSE;
- determining to authorize the charging session;
- responsive to the determining to authorize the charging session, transmitting a command to the EVSE to commence the charging session;
- and
- transmitting, to the mobile client device, a message that indicates that the charging session has been authorized.
