Abstract
The present disclosure provides a method for supporting installation of a contract certificate by a charging service providing device. As an example, the present disclosure may comprise the steps of: generating a first contract certificate for a first electric vehicle (EV); and transmitting the first contract certificate to a first external charging service providing device (CSP) with which a roaming contract has been made, so as to enable the first contract certificate to be installed in the first EV via the first external CSP in a roaming situation.
Claims20
A method of supporting an installation of a contract certificate in a charging service providing device (CSP), comprising:
- generating a first contract certificate for a first electric vehicle (EV);
- and
- transmitting the first contract certificate to a first external charging service providing device (CSP) in which a roaming contract has been established, so as to enable the first contract certificate to be installed in the first EV via the first external CSP in a roaming situation.
A charging service providing device, comprising:
- a processor;
- and
- a memory storing at least one program instruction to be executed by the processor,
- wherein the at least one program instruction, when executed by the processor, causes the processor to:
- generate a first contract certificate for a first electric vehicle (EV) and transmit the first contract certificate to a first external charging service providing device (CSP) so as to enable the first contract certificate to be installed in the first EV via the first external CSP;
- receive a second contract certificate for a second EV from a second external CSP and forward the second contract certificate to a certificate provisioning service device (CPS) to enable the CPS to store the second contract certificate;
- and
- when a contract certificate installation request is received from the second EV in a roaming situation where the second EV stays in a service network of the charging service providing device, make the second contract certificate stored in the CPS transmitted to and installed in the second EV.
A method of authorizing a charging of an electric vehicle (EV) for a PnC-based authorization in a roaming environment, comprising:
- generating a first contract certificate for a first electric vehicle (EV) to transmit the first contract certificate to a first external charging service providing device (CSP) so as to enable the first contract certificate to be installed in the first EV via the first external CSP;
- receiving a second contract certificate for a second EV from a second external CSP to forward the second contract certificate to a certificate provisioning service device (CPS) so as to enable the CPS to store the second contract certificate;
- and
- making the second contract certificate stored in the CPS to be transmitted to and installed in the second EV when a contract certificate installation request is received from the second EV in a roaming situation where the second EV stays in a service network of the charging service providing device, and authorizing a charging of the second EV based on a condition that the second contract certificate is installed in the second EV when the second EV makes an authorization request.
