Single SECC multiple EVSE support - is it implemented?

[thesems]

Hello, I'm interested in the use-case where there is a single SECC that talks with multiple EVSEs.
I'm interested in how this is supported in the ISO 15118-20 protocol (even though that this situation seems to be protocol-agnostic).

From a technical perspective, there is a single SECCHandler and a single EVSEController. However, there are multiple SECCCommunicationSession per IP address. Each of these sessions requires an evse_id, which is retrieved from the controller.
Given this, is it meant that there is a single EVSEController, that manages multiple EVSEs?

How exactly should one implement/use for iso15118-20 this use-case?

Thanks.
