Addition of grid codes regarding subdivision region information to be added to iso 15118-20

A computer-implemented method comprising:

• comparing, by a device comprising at least one processor, a first location code with a set of location codes, wherein the device is located on an electric vehicle (EV) and the first location code is received from an electric vehicle supply equipment (EVSE) situated at a location identified by the first location code;
• and
• in response to determining, by the device, a second location code in the set of location codes matches the first location code, enabling, by the device, a bidirectional power transfer (BPT) operation between a battery located onboard the EV and an electrical grid coupled to the EVSE.

A computer program product stored on a non-transitory computer-readable medium and comprising machine-executable instructions, wherein, in response to being executed, the machine-executable instructions cause a system located on an electric vehicle (EV) to perform operations, comprising:

• comparing a first location code with a set of location codes, wherein the first location code is received in a communication received from an electric vehicle supply equipment (EVSE) situated at a location identified by the first location code, and the communication comprises a ServiceDetailResponse message configured in compliance with International Organization of Standardization (ISO) 15118-20, and the first location code is a SubDivision code generated in compliance with ISO 3166-2;
• and
• in response to determining a second location code in the set of location codes matches the first location code, enabling a bidirectional power transfer (BPT) operation between a battery located onboard the EV and an electrical grid coupled to the EVSE.
