AI Technical Summary

Technical Problem

Existing conventional chargers do not support the Supported Provider List (SPL) feature, making it impossible to provide value-added services to electric vehicles and thus preventing the provision of SPL information to electric vehicles while maintaining interoperability.

Method used

Dedicated Value-Added Services (VAS) are provided through communication methods between the Power Supply Equipment Communication Controller (SECC) and the Electric Vehicle Communication Controller (EVCC). These services include receiving and sending service lists and parameters, generating a list of supported providers, supporting PnC and Plug and Charge authorization, and implementing SPL functionality using the message format defined by the ISO 15118-2 standard.

Benefits of technology

Without modifying the traditional charger architecture, a list of support providers for electric vehicles was implemented, supporting value-added services, maintaining interoperability, simplifying the business selection process, and improving user convenience.

Abstract

The present invention provides a communication method for constructing a new VAS environment such that a legacy charger supporting a charging service in V2G communication can provide a support provider list (SPL) to an EV, and an apparatus using the same. The communication method performed by the SECC comprises the steps of: receiving a request message for a service list of a charging service from the EV; providing a service list to the EV, the service list including a first service identifier of a dedicated VAS for providing an SPL for the EMSP; receiving a request message for parameters of the dedicated VAS from the EV; and providing the EV with at least one set of service parameters for the SPL supporting the dedicated VAS.
